Abstract
OBJECTIVE To evaluate the efficacy and safety of patient-tailored 3D printed brace in the treatment of adolescent idiopathic scoliosis (AIS), and to compare the health-related quality of life (HRQoL) of patients treated with 2 different types of brace. MATERIALS AND METHODS From September 2017 to August 2020, 103 AIS patients requiring non-operative management were prospectively recruited in this study. All patients were followed up every 6 months, clinical and radiologic examination were assessed at each follow-up time. Full-length anteroposterior radiographs of the spine in the standing position were obtained. At the last follow-up, each patient completed a standardized HRQoL questionnaire. Compliance is defined as that the patient insists on wearing the brace for ≥23 hours every day (full-time wearing) and follow-up every 6 months until bone maturity. The rate of major curve Cobb progression was defined that maximum Cobb angle of major curve greater than 6° compared with that at the initial diagnosis, or aggravated to more than 45° so that orthopedic surgery was recommended during treatment, which was defined as the rate of conversion to surgery. The effects of these 2 types of braces on the rate of major curve Cobb progression and HRQoL were analyzed by independent sample t test and χ2 test. RESULTS The thickness was 4 mm for thoracolumbosacral orthosis (TLSO) and 3 mm for 3D-printed brace (3DPB). In addition, compared with the material used in TLSO, the weight (600-800 g) of the 3DPB materials with the same area is reduced by about 25% to 30%. In our sample, 55 patients (49.1%) and 48 patients (33.1%) were respectively included in the 3DPB cohort and the TLSO cohort. The maximum Cobb angle of major curve in the 3DPB cohort was significantly lower than those in the TLSO cohort at 6 months, 12 months, and the last follow-up (P < 0.01). The thoracic kyphosis (TK) and lumbar lordosis (LL) of the 2 cohorts at the last follow-up were lower than those before brace treatment, in addition, there was a significant difference in TK (P = 0.001) and LL (P = 0.004) between the 2 cohorts at the follow-up. The scores of physical function, pain, self-image, mental health, and treatment satisfaction in the Chinese version of the 22-item questionnaire of the Scoliosis Research Society in the 3DPB cohort were higher than those in the TLSO cohort (P < 0.01 and P < 0.05, respectively). The scores of the 3DPB cohort were significantly higher than those of the TLSO group in the 4 dimensions (P = 0.008, 0.013, 0.015, and 0.002, respectively) of the EuroQol-5D health description system except for mobility, and the overall health status of EuroQol-5D was higher for the 3DPB cohort (P < 0.001). At the last follow-up, 1 patient in the 3DPB cohort and 10 patients in the TLSO cohort had major curve Cobb progression of greater than 6°, and the rate of major curve Cobb progression in the 3DPB cohort was significantly lower than that in the TLSO cohort (OR 14.2, 95% CI 1.7∼115.8, P < 0.01). One patient in the 3DPB and 7 patients in the TLSO cohorts received subsequent surgery or were recommended for surgery, and the rate of conversion to surgery was significantly lower than in the 3DPB cohort (OR 9.2, 95% CI 1.1∼77.9, P < 0.05). CONCLUSIONS A patient-tailored 3D-printed brace is lighter, thinner, and more comfortable than conventional braces in the treatment of AIS. It can substantially improve the HRQoL of patients and can significantly reduce the progression of major curve Cobb progression and rate of conversion of surgery.

Determining the association between the radiographic parameters and the SRS-22 scores in Chinese female patients with adolescent idiopathic scoliosis: does curve pattern matter? Br J Neurosurg 2024; 38:349-355. [PMID: 33491493 DOI: 10.1080/02688697.2021.1875396] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2020] [Revised: 06/16/2020] [Accepted: 01/08/2021] [Indexed: 10/22/2022]
Abstract
Background: The Scoliosis Research Society (SRS)-22 outcomes have been shown to be correlated with radiographic parameter of adolescent idiopathic scoliosis (AIS). A recent study suggested that curve patterns might play a role in assessing the influence of deformity on patient's reported outcomes. The aim of this study was to examine the relationship between radiographic parameters and SRS-22 questionnaire outcomes in female patients with adolescent AIS among the Chinese population based on five curve patterns.Patients and Methods: The radiographic data and SRS-22 questionnaires of 259 female AIS patients were reviewed. Radiographic measurements included: Cobb angle of the major curve, T1 tilt angle, apical vertebral rotation, apical vertebral translation (AVT), thoracic kyphosis, and lumbar lordosis. Curve patterns included single thoracic (T), single thoracolumbar/lumbar (TL), double thoracic (DT), double major (DM), and triple major (TM). The correlation between radiographic measurements and each domain in SRS-22 was determined by Pearson's correlation coefficient.Results: The curve magnitude and AVT of the major curve were found to be significantly correlated with the self-image domain in all cases (Cobb angle: r = -0.426, p = 0.002; AVT: r = -0.281, p=0.006) and in all curve patterns except for TM. Compared to other groups, the TM group had a significantly larger major curve than the DT group and TL group (p ≤ 0.004). In TM group, the self-image scores were lower than TL group (p =0.018), and the function scores were lower than that in T, TL (p < 0.001) and DM groups (p =0.013). In the DT group, the T1 tilt was significantly correlated with the self-image domain (r = -0.376, p =0.004). In the T group, coronal curve magnitude was significantly correlated with function domain (r = -0.397, p < 0.001).Conclusion: Our findings suggested curve patterns should be considered in evaluating the correlations between radiographic parameters and SRS-22 outcomes in patients with AIS.

Abstract
STUDY DESIGN Retrospective Cohort Study. OBJECTIVES Few previous studies have examined the relationship between preoperative disability and patient outcomes after complex adult spinal deformity surgery. In this study, we hypothesized that patients with worse preoperative disability would be more likely achieve a clinically significant improvement in their symptoms after surgery. METHODS Demographics, comorbidities, surgical data, and health related survey results were analyzed from a consecutive series of adults (≥18 years old) who underwent spinal deformity correction, instrumentation, and fusion. Patients included had 6 or more levels fused and their surgery performed at single institution between 2015 and 2018 with minimum 2 year follow up. RESULTS A total of 108 patients met inclusion criteria. Bivariate analysis demonstrated the following as having a greater probability of reaching minimum clinically important difference (MCID) at 2 years postoperatively: >50th percentile Oswestry Disability Index (ODI) score (ODI >36), cardiac comorbidities, and use of pelvic fixation, pedicle subtraction osteotomy, and transforaminal lumbar interbody fusion. Conversely, baseline Scoliosis research society score (SRS) >50th percentile (SRS ≥62) and use of vertebral column resection (VCR) were significant predictors of not reaching MCID at 2 years. On logistic regression analysis, >50th percentile ODI score (ODI >36) was identified as the only independent predictor of achieving MCID. CONCLUSIONS Patients with greater disability, independent of other preoperative or surgical factors, are more likely to have clinically significant improvement in their daily functioning after complex deformity surgery. For patients who undergo surgical intervention for severe or progressive deformity, including VCR, MCID might be an ineffective outcome measure.

Abstract
PURPOSE To develop a questionnaire for adolescent idiopathic scoliosis (AIS) patients undergoing physiotherapeutic scoliosis-specific exercises (PSSE) and to evaluate its content validity, structural validity, and reliability. METHODOLOGY Seven PSSE treatment experts checked the content validity of the Patient's Perception of Scoliosis-Specific Physiotherapy Questionnaire (Physio-IS). For each Physio-IS item, the content validity indexes must be ≥ 90%. Regarding structural validity and reliability 52 adolescents (ages 10-17) with AIS completed the questionnaire. Structural validity was assessed through exploratory factor analysis. Reliability was verified through internal consistency. RESULTS Physio-IS content was validated in three evaluation rounds, obtaining 100% expert agreement. About structural validity we identified four domains (cumulative explained variance = 68.2%): (1) specific knowledge (seven questions on understanding their scoliosis condition); (2) social repercussion (five questions about social relationship implications); (3) pain (two questions about scoliosis-associated pain); and (4) associated concern (apprehension/expectations regarding the future). The Physio-IS demonstrated very good internal consistency (Cronbach's alpha = 0.76-0.92). CONCLUSION The Physio-IS is a valid and reliable tool for assessing AIS patients undergoing PSSE and helping physiotherapists identify aspects requiring more attention, thus facilitating intervention strategies, as knowing the patient's perception of their condition or treatment is fundamental to AIS treatment success.

Abstract
Objective Approximately 50% of adolescents who have undergone scoliosis surgery still experience severe pain one year postoperatively. We explored the postoperative pain trajectory and the potential value of preoperative Thermal Quantitative Sensory Testing (T-QST) as predictor of chronic postsurgical pain after scoliosis surgery. Design Single-center prospective cohort study in adolescents undergoing scoliosis surgery. Outcomes Prevalence of chronic postsurgical pain (CPSP) one year after scoliosis surgery and postsurgical pain course during this year. The need for rescue medication and the relationship between pre-operative T-QST, acute pain and CPSP. Results Thirty-nine patients (mean age 13.9 years; SD 1.9 years) completed the study. One year postoperatively, ten patients (26%) self-reported pain [numeric rating scale (NRS) score ≥ 4]) when moving and two (5%) when in rest. Four of these patients (10.3%) experienced neuropathic pain. The pre-operative cold pain threshold was lower (p = 0.002) in patients with CPSP at 12 months. Preoperative cold and heat pain thresholds were correlated with the number of moderate or severe pain reports (NRS ≥ 4) in the first week postoperatively (r -.426; p = 0.009 and r.392; p = 0.016, respectively). Conclusions One year after scoliosis surgery, a significant part of patients (26%) still reported pain, some with neuropathic characteristics. Better diagnosis and treatment is needed; our study suggests that T-QST could be further explored to better understand and treat children with this negative outcome.

Abstract
Many measurement designs produce domain factors with small variances and factor loadings. The current study investigates the cause, prevalence, and problematic consequences of such domain factors. We collected a meta-analytic sample of empirical applications, conducted a simulation study on statistical power and estimation precision, and provide a reanalysis of an empirical example. The meta-analysis shows that about a quarter of all standardized domain factor loadings is in the range of - .2 < λ < .2 and about a third of all domains is measured by five or fewer indicators, resulting in small factor variances. The simulation study examines the associated difficulties concerning statistical power, trait recovery, irregular estimates, and estimation precision for a range of such realistic cases. The empirical example illustrates the challenge to develop measures that produce clearly interpretable domain factors. Study planning and interpretation need to take the (expected) sum of squared factor loadings per domain factor into account. This is relevant even if influences of domain factors are desired to be small, and equally applies to different model variants. We propose several strategies for how researchers may better unlock the bifactor model's full potential and clarify its interpretation.

Abstract
BACKGROUND The Scoliosis Research Society SRS-22 questionnaire is a standard tool to assess the Health-Related Quality of Life (HRQoL) in scoliosis patients but, because of cultural differences limited use among Arabic patients. The aim is to perform a cross-cultural adaptation and validation of Arabic version of Scoliosis Japanese Questionnaire-27 and test it on Saudi patients with adolescent idiopathic scoliosis (AIS). METHODS This a cross sectional study run between July 2021 and December 2022 recruited 194 patients. The cross-cultural adaptation process was performed using the American Association of Orthopedic Surgeons (AAOS) Outcomes Committee method. All patients had completed the Arabic version of Scoliosis Japanese Questionnaire-27 and SF-12 preoperatively and 3-month postoperatively. The validity and internal consistency were tested using the Intraclass correlation coefficient (ICC), Cronbach alpha, Pearson correlation coefficient, and confidence interval (CI). RESULTS We analyzed the result of 194 female adolescent patients. The average age is 14 ± 2.4 years (range from 10 to 21 years). The majority of patients have a Lenke type 1 curve (54 %). The overall Cronbach alpha (CA) of all domains of Scoliosis Japanese Questionnaire-27 is 0.92. However, the Cronbach alpha for the mental health (Q17,18,20,21,23,24) and, self-image (Q12-14,22,25,26) are 0.93 and 0.84 respectively. CONCLUSION The Arabic version of Scoliosis Japanese Questionnaire-27 is a reliable and valid instrument and can be applied to evaluate the quality of life in patients with AIS.

Abstract
Patient-reported outcome measures (PROMs) provide structured information on the patient's health experience and facilitate shared clinical decision-making. Registries that collect PROMs generate essential information about the clinical course and efficacy of interventions. Whilst PROMs are increasingly being used in adult orthopaedic registries, their use in paediatric orthopaedic registries is not well known. The purpose of this systematic review was to identify the frequency and scope of registries that collect PROMs in paediatric orthopaedic patient groups. In July 2023, six databases were systematically searched to identify studies that collected PROMs using a registry amongst patients aged under 18 years with orthopaedic diagnoses. Of 3190 identified articles, 128 unique registries were identified. Three were exclusively paediatric, 27 were majority paediatric, and the remainder included a minority of paediatric patients. One hundred and twenty-eight registries collected 72 different PROMs, and 58% of these PROMs were not validated for a paediatric population. The largest group of orthopaedic registries collected PROMs on knee ligament injuries (21%). There are few reported dedicated orthopaedic registries collecting PROMs in paediatric populations. The majority of PROMs collected amongst paediatric populations by orthopaedic registries are not validated for patients under the age of 18 years. The use of non-validated PROMs by registries greatly impedes their utility and impact. Dedicated orthopaedic registries collecting paediatric-validated PROMs are needed to increase health knowledge, improve decision-making between patients and healthcare providers, and optimise orthopaedic management.

Do Adolescent Idiopathic Scoliosis Patients With Vitamin D Deficiency Have Worse Spine Fusion Outcomes? J Pediatr Orthop 2023; 43:e209-e214.

Abstract
BACKGROUND Prior research has shown that patients with adolescent idiopathic scoliosis (AIS) have a higher prevalence of vitamin D deficiency compared with healthy peers. In adult orthopaedic populations, vitamin D deficiency has been shown to be a risk factor for higher reported pain and lower function. We investigated whether there was an association between vitamin D levels and AIS patient-reported outcomes, as measured by the Scoliosis Research Society (SRS-30) questionnaire. METHODS This was a single-center, cross-sectional study. Postoperative AIS patients were prospectively recruited during routine follow-up visits, 2 to 10 years after spine fusion. Vitamin D levels were measured by serum 25-hydroxyvitamin D (ng/mL). Patients were categorized based on vitamin D level: deficient (<20 ng/mL), insufficient (20 to 29 ng/mL), or sufficient (≥30 ng/mL). The correlation between vitamin D levels and SRS-30 scores was analyzed using multivariable analysis and pair-wise comparisons using Tukey method. RESULTS Eighty-seven AIS patients (83% female) were enrolled who presented at median 3 years (interquartile range: 2 to 5 y; range: 2 to 10 y) after spine fusion. Age at time of surgery was mean 15 (SD±2) years. Major coronal curves were a mean of 57 (SD±8) degrees preoperatively and 18 (SD±7) degrees postoperatively. It was found that 30 (34%) of patients were vitamin D sufficient, 33 (38%) were insufficient, and 24 (28%) were deficient. Although there was no correlation between vitamin D level and Pain, Mental Health, or Satisfaction domains ( P >0.05), vitamin D-deficient patients were found to be younger ( P <0.001) and had lower SRS-30 function ( P =0.002), Self-image ( P <0.001), and total scores ( P =0.003). CONCLUSIONS AIS patients with vitamin D deficiency (<20 ng/mL) are more likely to be younger age at time of surgery, and report lower Function, Self-image, and Total SRS-30 scores postoperatively. Further work is needed to determine whether vitamin D supplementation alters curve progression and patient outcomes. LEVEL OF EVIDENCE Level II-prognostic study.

Abstract
INTRODUCTION Scoliosis Research Society-22 revised (SRS-22r) is the common questionnaire used to evaluate health related quality of life (HRQOL) for young people with adolescent idiopathic scoliosis (AIS). The aim of this study is to evaluate its content validity for this population. METHODS In-depth semi-structured interviews were conducted with a purposive sample of young people with AIS (Cobb angle ≥25˚, aged 10-18 years). Concept elicitation was used to evaluate the influence of AIS on participants' HRQOL. Participant information sheets and consent/assent forms were age relevant. Topic guide was informed by the SRS-22r and existing evidence. Interviews were audio and video recorded, transcribed verbatim, coded, and analysed using thematic analysis. Derived themes/codes were compared with SRS-22r contents (domains/items). RESULTS Eleven participants (mean age 14.9 years [SD = 1.8]; 8 female) were recruited. The mean curve size was 47.5° [SD = 18°] and participants had been managed via different approaches. Four main themes emerged with associated subthemes: 1) Physical effects related to physical symptoms (back hurt, stiffness) and body asymmetry (uneven shoulders), 2) Activity-related effects showed impact on mobility (sitting for long periods), self-care (dressing), and school activities (focus during lessons), 3) Psychological effects revealed emotional (feel worried), mental (sleep quality), and body image effects (hide back from others), 4) Social effects (participation in school and leisure activities), and school, friends and mental health support. A weak association was found between items of the SRS-22r and the identified codes. CONCLUSION The SRS-22r does not adequately capture important concepts that relate to HRQOL of adolescents with AIS. These findings support revision of the SRS-22r, or the development of a new patient reported outcome measure to evaluate HRQOL of adolescents with AIS.

Abstract
PURPOSE Adolescent idiopathic scoliosis (AIS) affects up to 3% of otherwise healthy adolescents. The extreme long-term outcomes of nonoperative treatment are underreported. This study aimed to investigate the long-term outcome of nonoperative-treated AIS patients. Comparison between a bracing and an observation approach were performed. METHODS In a retrospective cohort study, 20 nonoperatively treated AIS patients were observed concerning patient-related outcome measures (PROM) (visual analog scale (VAS), Short Form Health Survey 36 item (SF 36), Scoliosis Research Society (SRS 24), Oswestry Low Back Pain Disability Index (ODI), Psychological General Well-Being Index (PGWBI)), radiological curve progression and health-related quality of life (HRQoL). Baseline characteristics and radiological imaging were collected. At follow-up, anteroposterior and lateral X-rays as well as questionnaires were analyzed. RESULTS Twenty patients (16 females, mean age: 14.6 ± 3.2 years) with a follow-up time of 42 ± 9 years were included. Nine patients (initial Cobb 35° ± 19°) were treated with bracing for a mean time of 26 ± 9 months, while the other 11 patients (initial Cobb 29° ± 11°) were observed. The primary curve progressed from 32° ± 15° to 52° ± 25° in average with no significant difference between the cohorts (p = 0.371). At final follow-up, a mean ODI score of 7 ± 7.9 points with no difference depending on the treatment (p = 0.668) was seen. No significant differences were observed for PROMs. Curve magnitude correlated neither at diagnosis (p = 0.617) nor at follow-up (p = 0.535) with the ODI score at final follow-up. CONCLUSION After a mean of 42 years, patients with nonoperative treatment of moderate AIS demonstrated a good clinical outcome despite progression of the deformity. LEVEL OF EVIDENCE Level IV, therapeutic study.

Abstract
PURPOSE In patients with adult spinal deformity, it was previously shown that 16 of the non-management items of the SRS-instrument showed a better fit to the theoretical four-factor model (pain, function, self-image, mental health) than did all 20 items. Whether the same phenomenon is observed in data from younger (< 20y) patients, for whom the questionnaire was originally designed, is not currently known. METHODS Confirmatory factor analysis was used to evaluate the factor structure of the 20 non-management items of the SRS-instrument completed by 3618 young patients with spinal deformity (75.5% female; mean age, 15.0 ± 2.0 years) and of its equivalence across language versions (2713 English-speaking, 270 Spanish, 264 German, 223 Italian, and 148 French). The root mean square error of approximation (RMSEA) and comparative fit index (CFI) indicated model fit. RESULTS Compared with the 20-item version, the 16-item solution significantly increased the fit (p < 0.001) across all language versions, to achieve good model fit (CFI = 0.96, RMSEA = 0.06). For both 16-item and 20-item models, equivalence across languages was not reached, with some items showing weaker item-loading for some languages, in particular German and French. CONCLUSION In patients with adolescent idiopathic scoliosis, the shorter 16-item version showed a better fit to the intended 4-factor structure of the SRS-instrument. The wording of some of the items, and/or their equivalence across language versions, may need to be addressed. Questionnaire completion can be a burden for patients; if a shorter, more structurally valid version is available, its use should be encouraged.

Abstract
PURPOSE To systematically review and synthesise the evidence on the measurement properties of patient-reported outcome measure (PROMs) used to assess the quality of life in patients with adult scoliosis. METHOD Based on the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) guidelines and a published protocol, a two-stage search was conducted and reported in line with the Preferred Reporting Items for Systematic review and Meta-analysis (PRISMA). Stage one identified all studies of patients with adult scoliosis which included PROMs of health-related quality of life (HR-QOL). Databases including AMED, CINAHL, EMBASE, Medline, PsychINFO and Pubmed were searched from inception until 31st December 2020. This derived list of PROMs, was then utilised for a stage 2 search to identify studies which evaluated the measurement properties of the PROMs. Two reviewers independently performed the searches, study screening, selection and risk of bias assessment using the COSMIN tool. The overall quality of the evidence was assessed using a modified Grading of Recommendations Assessment, Development and Evaluation approach. RESULTS Stage one yielded 16 PROMs of HR-QOL with the Oswestry Disability Index (ODI) and Scoliosis Research Society-22 (SRS-22) the most used. Stage two identified three stage one PROMs that fulfilled eligibility criteria: SRS-22, ODI and SRS-22r; with five studies investigating measurement properties in an adult scoliosis population. The SRS-22 was the most comprehensively evaluated PROM in this cohort with very low-quality evidence indicating indeterminate reliability, sufficient construct validity and sufficient responsiveness of the SRS-22. There is very low-quality evidence indicating sufficient responsiveness of the ODI. There is very low-quality evidence indicating indeterminate cross-cultural validity for the SRS-22r. All other measurement properties in the SRS-22, ODI and SRS-22r have not been evaluated. CONCLUSION A large number of PROMs are being utilised in the adult scoliosis population and of these, the most commonly utilised are the ODI and SRS-22. The SRS-22, ODI and SRS-22r are the only PROMs to have had their measurement properties evaluated in the adult scoliosis population. The findings of this systematic review are that there currently is not sufficient evidence on the measurement properties of any PROMs in adult scoliosis. Further research is now urgently required to assess the measurement properties of these PROMs.

Abstract
Adolescent idiopathic scoliosis (AIS) is a progressive deformity of the spine. Scoliotic curves progress until skeletal maturity leading, in rare cases, to a severe deformity. While the Cobb angle is a straightforward tool in initial curve magnitude measurement, assessing the risk of curve progression at the time of diagnosis may be more challenging. Epigenetic and genetic markers are potential prognostic tools to predict curve progression. The aim of this study is to review the available literature regarding the epigenetic and genetic factors associated with the risk of AIS curve progression. This review was carried out in accordance with Preferential Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. The search was carried out in January 2022. Only peer-reviewed articles were considered for inclusion. Forty studies were included; fifteen genes were reported as having SNPs with significant association with progressive AIS, but none showed sufficient power to sustain clinical applications. In contrast, nine studies reporting epigenetic modifications showed promising results in terms of reliable markers. Prognostic testing for AIS has the potential to significantly modify disease management. Most recent evidence suggests epigenetics as a more promising field for the identification of factors associated with AIS progression, offering a rationale for further investigation in this field.

Abstract
OBJECTIVE Although the health impact of adult symptomatic lumbar scoliosis (ASLS) is substantial, these patients often have other orthopedic problems that have not been previously quantified. The objective of this study was to assess disease burden of other orthopedic conditions in patients with ASLS based on a retrospective review of a prospective multicenter cohort. METHODS The ASLS-1 study is an NIH-sponsored prospective multicenter study designed to assess operative versus nonoperative treatment for ASLS. Patients were 40-80 years old with ASLS, defined as a lumbar coronal Cobb angle ≥ 30° and Oswestry Disability Index ≥ 20, or Scoliosis Research Society-22 questionnaire score ≤ 4.0 in pain, function, and/or self-image domains. Nonthoracolumbar orthopedic events, defined as fractures and other orthopedic conditions receiving surgical treatment, were assessed from enrollment to the 4-year follow-up. RESULTS Two hundred eighty-six patients (mean age 60.3 years, 90% women) were enrolled, with 173 operative and 113 nonoperative patients, and 81% with 4-year follow-up data. At a mean (± SD) follow-up of 3.8 ± 0.9 years, 104 nonthoracolumbar orthopedic events were reported, affecting 69 patients (24.1%). The most common events were arthroplasty (n = 38), fracture (n = 25), joint ligament/cartilage repair (n = 13), and cervical decompression/fusion (n = 7). Based on the final adjusted model, patients with a nonthoracolumbar orthopedic event were older (HR 1.44 per decade, 95% CI 1.07-1.94), more likely to have a history of tobacco use (HR 1.63, 95% CI 1.00-2.66), and had worse baseline leg pain scores (HR 1.10, 95% CI 1.01-1.19). CONCLUSIONS Patients with ASLS have high orthopedic disease burden, with almost 25% having a fracture or nonthoracolumbar orthopedic condition requiring surgical treatment during the mean 3.8 years following enrollment. Comparisons with previous studies suggest that the rate of total knee arthroplasty was considerably greater and the rates of total hip arthroplasty were at least as high in the ASLS-1 cohort compared with the similarly aged general US population. These conditions may further impact health-related quality of life and outcomes assessments of both nonoperative and operative treatment approaches in patients with ASLS.

Abstract
PURPOSE Idiopathic scoliosis (IS) patients can have body dissatisfaction which can affect their perception of health. Two body image measures, the Spinal Appearance Questionnaire (SAQ) and the Body Image Disturbance Questionnaire-Scoliosis (BIDQ-S), have been used in pediatric IS with variable correlation to the SRS-22r and radiographs, but have not been compared to each other. As patient reported outcomes (PROs) continue to be highlighted in large database studies and national hospital ranking system scoring, we should narrow use to the best and most efficient. We aim to determine which of two better correlates to pediatric IS patients' radiographs and quality of life (QoL) scores. METHODS Consecutive IS patients aged 10-19 years old without surgery prospectively completed BIDQ-S, SAQ, SRS-22r, and PedsQL self-reported outcome measures. BIDQ-S and SAQ were compared in correlation to the two QoL surveys, as well as to radiographic major curve, shoulder asymmetry, lateral upright ribcage offset at apex, and coronal/sagittal balance. Spearman's r was used for correlations. RESULTS 104 surveys with mean age 14.4 years and mean major curve 42° (14°-74°) were included. BIDQ-S and SAQ scores strongly correlated to each other (r = 0.76), but BIDQ-S had a stronger correlation to total SRS-22r (- 0.75 vs - 0.61 SAQ), PedsQL total (- 0.76 vs - 0.55) and better or no difference in each SRS-22r and PedsQL domain. Both poorly correlated to radiographs (main curve: r = 0.32 BIDQ-S, 0.31 SAQ). CONCLUSION The BIDQ-S correlates better to SRS-22r and PedsQL for pediatric IS patients than the SAQ. Neither correlate well to radiographs. LEVEL OF EVIDENCE III.

Abstract
STUDY DESIGN Methodological. OBJECTIVE Turkish validity and reliability study of Scoliosis Research Society-30 (SRS-30) questionnaire. SUMMARY OF BACKGROUND DATA SRS-30 is the most current questionnaire of SRS, which is widely used in the evaluation of the treatment of patients with idiopathic scoliosis. There is no validity and reliability study for the Turkish language. METHODS All translation and cross-cultural adaptation stages of the SRS-30 English version to Turkish were implemented. SRS-30 Turkish and Short Form-36 questionnaires were administered to 96 patients with adolescent idiopathic scoliosis simultaneously. Two weeks later, the SRS-30-Turkish version was applied again. Internal validity was examined using the Rasch model, and external construct validity (convergent validity) was evaluated with the Spearman rho correlation test. Person Separation Index was used for reliability. The internal consistency was analyzed with Cronbach alpha. For test re-test reliability, intraclass correlation coefficient between the two measurements was calculated. RESULTS As a result of the Rasch analysis, it was observed that the Turkish version of SRS-30 has a multidimensional structure and the disordered threshold problem was observed in some items. Overall fit is provided for each of the four sub-dimensions of SRS-30 Turkish. There was no difference in the functioning of the items in terms of gender and age groups. The lowest Person Separation Index value was obtained with 0.539 in the satisfaction of the treatment sub-dimension. Cronbach alpha values were over 0.70 for all domains. The intraclass correlation coefficient value was found in satisfaction with management dimension (0.463) and above 0.60 in other dimensions. CONCLUSION It was concluded that the SRS-30 Turkish questionnaire was valid and reliable in evaluating the treatment of patients with adolescent idiopathic scoliosis. Considering the studies related to SRS scales in the literature, especially those applied Rasch analysis, it is seen that the reply categories of the items should be reviewed.Level of Evidence: 2.

Abstract
BACKGROUND Adult scoliosis represents a distinct subgroup of scoliosis patients for whom the diagnosis can have a large impact on their health-related quality of life (HR-QOL). Therefore, HR-QOL patient-reported outcome measures (PROMs) are essential to assess disease progression and the impact of interventions. The objective of this systematic review is to evaluate the measurement properties of HR-QOL PROMs in adult scoliosis patients. METHODS We will conduct a literature search, from their inception onwards, of multiple electronic databases including AMED, CINAHL, EMBASE, Medline, PsychINFO and PubMed. The searches will be performed in two stages. For both stages of the search, participants will be aged 18 and over with a diagnosis of scoliosis. The primary outcome of interest in the stage one searches will be studies which use PROMs to investigate HR-QOL as defined by the Core Outcome Measures in Effectiveness Trials (COMET) taxonomy, the secondary outcome will be to assess the frequency of use of the various PROMs. In stage two, the primary outcome of interest will be studies which assess the measurement properties of the HR-QOL PROMs identified in stage one. No specific measurement property will be given priority. No planned secondary outcomes have been identified but will be reported if discovered. In stage one, the only restriction on study design will be the exclusion of systematic reviews. In Stage two the only restriction on study design will be the exclusion of full-text articles not available in the English language. Two reviewers will independently screen all citations and abstract data. Potential conflicts will be resolved through discussion. The study methodological quality (or risk of bias) will be appraised using the Consensus-based Standards for the selection of Health Measurement Instruments (COSMIN) checklist. The overall strength of the body of evidence will then be assessed using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach. A narrative synthesis will be provided with information presented in the main text and tables to summarise and explain the characteristics and findings of the included studies. The narrative synthesis will explore the evidence for currently used PROMs in adult scoliosis patients and any areas that require further study. DISCUSSION The review will help clinicians and researchers identify a HR-QOL PROM for use in patients with adult scoliosis. Findings from the review will be published and disseminated through a peer-reviewed journal and conference presentations.

Physical Functioning in Adolescents with Idiopathic Scoliosis: A Systematic Review of Outcome Measures and Their Measurement Properties. Spine (Phila Pa 1976) 2021; 46:E985-E997. [PMID: 33496543 DOI: 10.1097/brs.0000000000003969] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 02/01/2023]
Abstract
STUDY DESIGN A systematic review. OBJECTIVE To summarize evidence on measurement properties of Outcome Measures (OM) used to assess physical functioning in adolescents with idiopathic scoliosis (AIS). SUMMARY OF BACKGROUND DATA The AIS is a common spine deformity in those aged 10 to 18 years old. Associated health problems (e.g., back pain) significantly impact the quality of life (QoL). One important domain in QoL is physical functioning, which can be measured with patient-reported outcome measures (PROM), performance-based outcome measures (PBOM), and body structure and function OM. Adequate measurement properties of OM are important for precision in research and practice. METHODS A two-staged search strategy was performed on electronic databases up to December 2019. Search one revealed a list of OM was used for physical functioning assessment in AIS. Search two identified studies that evaluated the measurement properties of OM in AIS; using the list identified in search one. Two independent reviewers determined study eligibility, risk of bias assessment (COnsensus-based Standards for the selection of health Measurement INstruments [COSMIN] checklist), and performed data extraction. The level of evidence was established using a modified GRADE approach. RESULTS Search one yielded: 28 PROM, 20 PBOM, and 10 body structure and function OM. Search two revealed: 16 measurement properties studies for PROM, one for PBOM, and three for body structure and function measures. Construct validity, reliability, and responsiveness of most PROM has been established in AIS, but not content validity or internal consistency (moderate evidence). Construct validity was sufficient for the Timed Up and Go test and body structure and function measures (very low to low evidence). CONCLUSION Currently, physical functioning is evaluated with a variety of measures in AIS. The majority of measurement properties studies evaluated PROM with a paucity of information on measurement properties of PBOM and body structure and function OM. Based on COSMIN methodology, none of the OM identified in this review can be recommended with confidence in individuals with AIS.Level of Evidence: 2.

Abstract
We aimed to evaluate the reliability and validity of the adapted Korean version of the Italian Spine Youth Quality of Life (ISYQOL) questionnaire. Translation/retranslation of the English version of ISYQOL was conducted, and all steps of the cross-cultural adaptation process were performed. The Korean version of the ISYQOL and the previously validated Scoliosis Research Society-22 (SRS-22) questionnaire were mailed to 120 consecutive idiopathic scoliosis patients wearing brace. Factor analysis and reliability assessment by kappa statistics of agreement for each item, the intraclass correlation coefficient (ICC) and Cronbach's α were conducted. Construct validity was also evaluated by comparing the responses of ISYQOL with the responses of SRS-22 by using Pearson's correlation coefficient. Factor analysis extracted 2 factors. All items had a kappa statistics of agreement greater than 0.6. The ISYQOL showed good test/re-test reliability (ICC = 0.812). Internal consistency of Cronbach's α was found to be very good (α = 0.873). The Korean version of ISYQOL showed good significant correlation with SRS-22 total score and with single SRS-22 domains scores. The adapted Korean version of the ISYQOL was successfully translated and showed acceptable measurement properties, and as such, is considered suitable for outcome assessments in the Korean speaking patients with idiopathic scoliosis.

Abstract
OBJECTIVE Obstructive sleep apnea (OSA) is highly prevalent in children and requires an expensive and relatively unavailable sleep study for diagnosis. This study was undertaken to translate the previously validated pediatric OSA screening tool (POSAST) to the Thai language and assess its accuracy and test-retest reliability in at-risk symptomatic children. STUDY DESIGN Prospective cross-sectional cohort study. METHODS Pediatric patients clinically referred for suspected OSA who underwent overnight polysomnography (PSG) were recruited, and caregivers completed the Thai version of the POSAST. The same questionnaire was completed again after 2-4 weeks. The reliability of the questionnaire was determined by internal consistency and test-retest reliability. The validity of the questionnaire was assessed by constructing receiver operating characteristic (ROC) curves to identify the equation-derived score and total additive score cutoff points that identify high risk for moderate and severe OSA (AHI of ≥ 5 events/h). RESULTS One hundred and ten subjects completed the study. The mean age was 8.4 ± 2.9 years. The mean apnea-hypopnea index (AHI) was 10.9 ± 11.9 events/h. Test-retest reliability (Pearson correlation coefficient = 0.96, p < .001) and internal consistency between each question (Cronbach's alpha coefficient = 0.82, p < .001) were excellent. An equation-derived score cut-off of 1.9 yielded 78.4% sensitivity, 50.0% specificity, 76.3% positive predictive value (PPV), and 52.9% negative predictive value (NPV), while a total additive score cut-off of 8 corresponded to 81.1% sensitivity, 52.8% specificity, 77.9% PPV, and 57.6% NPV for diagnosing moderate and severe OSA (AHI ≥ 5 events/h). CONCLUSION The internal consistency and reproducibility of the Thai version of the POSAST are satisfactory, display acceptable validity, and the instrument can be used for screening symptomatic Thai children for OSA.

Spine Deform 2021; 9:1247-1251. [PMID: 33759111 PMCID: PMC8363544 DOI: 10.1007/s43390-021-00330-6] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/22/2021] [Accepted: 03/14/2021] [Indexed: 12/25/2022]
Abstract
BACKGROUND Adolescent idiopathic scoliosis (AIS) is a frequent disorder. Since patients with AIS are typically as active as age-matched controls and post-operative reduction in physical activity has detrimental effects on their well-being, return to sport (RTS) is an important perioperative concern. Aim of the present study is to review the literature concerning return to sport after spinal fusion for AIS. METHODS This work was carried out in accordance with Preferential Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. The search was carried out in December 2020. Only peer-reviewed randomized controlled trials (RCTs), retrospective studies (RS), retrospective case series (RCS) and perspective cohort studies (PCS) were considered for inclusion. RESULTS Six studies were included; only one of them was prospective. All the authors reported a time to RTS ranging between 6 and 18 months. Between 28 and 36.6% of all patients changed sport, choosing lower impact activities, mostly due to loss of flexibility of the spine. No complications due to return to play were noted. CONCLUSION According to current evidence, patients who received spinal arthrodesis for AIS can safely return to any sport, even those that require extreme levels of spinal and pelvic movements such as gymnastics and golf. As there is little evidence, however, of the spinal loading that occurs during such movements, there is a lack of scientific evidence-based recommendations or guidelines surgeons and other health care providers can follow. Prospective comparative studies are needed to investigate these biomechanical and clinical issues. LEVEL OF EVIDENCE Level III.

Abstract
BACKGROUND AND PURPOSE Treatments that prevent worsening kyphosis are important due to the progressive nature of kyphosis with aging. We assessed long-term efficacy of treatment effects after a short-term kyphosis exercise and posture training intervention in a cohort study among older adults with hyperkyphosis, and investigated whether long-term treatment effects differ among males and females. METHODS In the original kyphosis intervention, 112 older adults enrolled in a waitlist design randomized controlled trial. One hundred three participants, mean age 70.0 (5.7) years and kyphosis 52.0° (7.4°), completed a twice weekly, 3-month, group exercise and posture training intervention, and were eligible to enroll in the follow-up study. We compared (1) change in outcomes pre-/postintervention to change postintervention over the follow-up period, (2) change in outcomes pre-/postintervention and postintervention to follow-up, stratified by sex, and (3) long-term change postintervention to follow-up in males and females. Primary outcome was change in kyphometer-measured thoracic kyphosis. Secondary outcomes were change in lumbar lordosis, objective measures of physical function, self-reported measures of physical activity, and health-related quality of life (HRQoL). RESULTS AND DISCUSSION Forty-three participants, 42% of the eligible cohort, returned for follow-up, a mean 3.0 (0.7) years after completing the original intervention. Participants (27 females and 16 males) were 73.8 (6.1) years old, with mean kyphosis 48.9° (11.9°) at follow-up. Kyphosis declined -1.5° (95% confidence interval [CI]: -3.9° to 1.0°) postintervention to follow-up and this was no different than change pre-/postintervention, P = .173. Lordosis improved 8.9° (95% CI: 6.2° to 11.6°), more than change pre-/postintervention, P < .001. Gait speed measure of physical function increased 0.08 (95% CI: 0.02 to 0.14) m/s, Physical Activity Scale for the Elderly (PASE) measure of physical activity increased 4 (95% CI: -16 to 24) points, and Patient-Reported Outcomes Measurement Information System (PROMIS) mental health T-score measure of HRQoL increased 1.1 (95% CI: -1.0 to 3.1) points, but these improvements were not significantly more than change pre-/postintervention, P > .050. Other measures of physical function (modified Physical Performance Test [PPT], Timed Up and Go, and 6-minute walk) and HRQoL (Scoliosis Research Society [SRS-30] self-image and PROMIS physical function and physical health) declined at follow-up, significantly more than change pre/postintervention, P ≤ .050. Comparing change in outcomes pre-/postintervention and postintervention to follow-up, stratified by sex, both males and females increased lordosis, and decreased modified PPT and 6-minute walk measures of physical function, P < .050. Males and females differed in long-term change postintervention to follow-up. Time loaded standing and PASE improved in females compared with males, P = .008 and P = .092, respectively, and PROMIS mental health, physical health, and physical function declined in females compared with males, P = .073, P = .025, and P = .005, respectively. CONCLUSIONS In our follow-up study, a mean of 3.0 (0.07) years after a 3-month kyphosis exercise and posture training intervention, kyphosis maintained and did not progress as expected with age. There was long-term improvement in lordosis. Compared with treatment effects from the short-term intervention, gait speed maintained equally well in males and females, while trunk endurance improved in females. Further investigation of long-term benefits of a short-term kyphosis exercise and posture training intervention is warranted.

Effect of Etiology, Radiographic Severity, and Comorbidities on Baseline Parent-Reported Health Measures for Children with Early-Onset Scoliosis. J Bone Joint Surg Am 2021; 103:803-811.

Abstract
BACKGROUND The Classification of Early-Onset Scoliosis (C-EOS) allows providers to differentiate patients, for clinical and research purposes, on the basis of the etiology of their disease as well as radiographic parameters. The Early Onset Scoliosis Questionnaire (EOSQ) is the first disease-specific, parent-reported HRQOL (health-related quality-of-life) outcome measure for this condition. We sought to determine the influence of the C-EOS etiology designation, radiographic parameters, and medical comorbidities on EOSQ scores to differentiate quality of life in this heterogeneous patient population. We hypothesized that baseline EOSQ scores for patients with EOS would be strongly affected by the C-EOS etiology designation. METHODS The analysis included prospectively enrolled patients with EOSQ scores recorded in a multicenter EOS database prior to intervention for the EOS. EOSQ scores were compared across C-EOS etiologies, severity of disease based on radiographic measurements, and patient comorbidities prior to scoliosis intervention. RESULTS Six hundred and ten patients with EOS were available for analysis; 119 had congenital, 201 had idiopathic, 156 had neuromuscular, and 134 had syndromic EOS. In multivariate analysis, neuromuscular and syndromic etiologies were associated with lower scores than congenital and idiopathic etiologies in many EOSQ domains including general health, transfer, daily living, fatigue/energy level, and emotion. Patients with neuromuscular EOS had the lowest EOSQ scores in general. Congenital and idiopathic EOS did not differ from each other in any EOSQ domain. Coronal Cobb and kyphosis angles had significant inverse but generally weak correlations with EOSQ domains. Individual medical comorbidities had a minor effect on certain domains while American Society of Anesthesiologists (ASA) class and total number of comorbidities had inverse correlations with most domains. CONCLUSIONS The underlying etiology of EOS appears to have a significant influence on the parent-reported HRQOL outcomes of the disease. Specifically, syndromic and neuromuscular C-EOS diagnoses are associated with lower EOSQ scores before treatment compared with congenital and idiopathic diagnoses. Radiographic measurements of severity have a relatively small influence on EOSQ scores. These baseline differences in C-EOS-designated etiology should be accounted for in studies comparing outcomes of treatment for this heterogeneous patient population.

Abstract
AIMS The aim of this retrospective study was to compare the correction achieved using a convex pedicle screw technique and a low implant density achieved using periapical concave-sided screws and a high implant density. We hypothesized that there would be no difference in outcome between the two techniques. METHODS We retrospectively analyzed a series of 51 patients with a thoracic adolescent idiopathic scoliosis. There were 26 patients in the convex pedicle screw group who had screws implanted periapically (Group 2) and a control group of 25 patients with bilateral pedicle screws (Group 1). The patients' charts were reviewed and pre- and postoperative radiographs evaluated. Postoperative patient-reported outcome measures (PROMs) were recorded. RESULTS The number of implants (14.5 vs 17.1) and the implant density (1.5 vs 1.9) were significantly lower in Group 2 (p < 0.001). Operating time was 27 minutes shorter in Group 2 than in Group 1, with a mean of 217 minutes (SD 50.5; 120 to 346). The duration of surgery per instrumented vertebra was reduced by 19% in Group 2 (p = 0.011). No statistical difference was found in the postoperative Cobb angle, vertebral rotation, the relative correction achieved, or postoperative PROMs. CONCLUSION Despite a lower implant density and achieving correction through a convex rod, surgical correction of the Cobb angle and vertebral body rotation was similar in both groups. Periapical pedicle screws and primary correction on the concave side do not seem to be mandatory in order to achieve good surgical results in idiopathic thoracic scoliosis. The operating time was shorter in the group with lower implant density. In conclusion, the technique provided good results and has the potential to reduce complications and costs.

Abstract
STUDY DESIGN Validation study. BACKGROUND Scoliosis Research Society-30 (SRS-30), Milwaukee-USA, questionnaire is a useful and valid instrument for evaluation of health-related quality of life (HRQOL) including pain in idiopathic scoliosis. There has not been a single validation or translation attempt of any of the SRS questionnaires in Indian languages until now. OBJECTIVES The objective of this study was to translate and cross culturally adapt SRS-30 questionnaire in one of the widely spoken south Indian language, Kannada for its accuracy. METHODS The permission for the cross cultural adaptation and validation of SRS-30 questionnaire into Kannada language was taken from the Scoliosis Research Society, Milwaukee, USA. The American Association of Orthopaedic Surgery and the international quality of life assessment (IQOLA) guidelines were used for this adaptation. The translated version of SRS-30 questionnaire was tested on twenty nine girls with idiopathic scoliosis before and after scientific exercise approach to scoliosis (SEAS). The average age of the girls was 11.3 years. Internal consistency of the instrument was determined with Cronbach α. RESULTS The Kannada version of SRS-30 questionnaire showed an overall internal consistency of 0.845 and 0.905 for pre and post SEAS, respectively. CONCLUSION The south Indian language, Kannada, version of SRS-30 showed high internal consistency for all domains and for the overall score, proving its validity and reliability for analysing HRQOL in idiopathic scoliosis patients.

Abstract
BACKGROUND Hyperkyphosis is common in older adults and associated with low physical function and reduced health related quality of life (HrQol). Improved kyphosis has been previously established in kyphosis-targeted interventions in randomized controlled trials in older adults with hyperkyphosis; however, evidence for improved physical function is conflicting. Few studies have investigated change in physical function after a targeted kyphosis intervention in older adults with low physical function. The primary aim in this descriptive study was to explore change in physical function after a progressive high-intensity 3-month targeted kyphosis exercise and posture training intervention in older adults with low physical function and hyperkyphosis. Secondary aims were to explore change in HrQol, spinal strength and spinal curvature, and adherence and safety of the intervention. METHODS In this secondary analysis of the Specialized Center of Research (SCOR) Kyphosis randomized trial, 101 community dwelling older men and women with hyperkyphosis who completed the intervention were divided into a low function group (LFG) and high function group (HFG). Baseline characteristics were compared between LFG and HFG. Physical function, HrQol, spinal strength and spinal curvature (kyphosis and lordosis) pre/post intervention change scores were explored within and between groups. Adherence and adverse events were examined in the LFG and HFG. RESULTS Twenty-six (26%) older adults were LFG, mean Short Phyiscal Performance Battery (SPPB) 9.62 (SD = 1.17) points. At baseline, the LFG was older than HFG (p = 0.005), experienced more pain, (p = 0.060), had worse physical function and HrQol (p ≤ 0.001), and comparable kyphosis (p = 0.640). SPPB changed 0.62 (95% CI: - 0.20 to 1.44) points in the LFG and - 0.04 (95%CI: - 0.28 to 0.19) points in the HFG, p = 0.020. Gait speed changed 0.04 (95% CI: - 0.02 to 0.10) m/s in the LFG. Kyphosis improved equally in both groups. Adherence to the intervention was 83% in the LFG and 79% in the HFG. There were no adverse events in either group. CONCLUSIONS Older adults with low physical function and hyperkyphosis may improve physical function after a kyphosis targeted intervention. Older adults with low physical function may safely participate in targeted high-intensity kyphosis exercise and posture training. This observation needs to be confirmed in larger adequately powered studies. TRIAL REGISTRATION Clinicaltrials.gov identifier: NCT01766674 .

Abstract
Adult spinal deformity (ASD) is a diagnosis that encompasses heterogeneous disorders with an increasing prevalence. This increasing prevalence may be due to greater patient longevity or greater awareness of available treatments. Outcome assessment in ASD has evolved over the last 3 decades from physician-based assessments to a patient-centered perception of improvement. Outcome assessment that is reliable, accurate and responsive to change is especially important in ASD, as surgical treatment is known to carry a high cost and complication rate Glassman (Spine Deform 3:199-203, 2015); Glassman (Spine (Phila Pa 1976) 32: 2764-2770, 2007); Smith (J Neurosurg Spine 25:1-14, 2016). In an era of value-based care, diagnosis associated with such heterogeneity and high cost must provide sound evidence to support the cost versus outcome ratio. Numerous general health and disease specific patient-reported outcome measures (PROMs) have been utilized in ASD. We discuss these instruments in detail in the following state-of-the-art review.

Preoperative patient-reported outcome score thresholds predict the likelihood of reaching MCID with surgical correction of adult spinal deformity. Spine Deform 2021; 9:207-219. [PMID: 32779122 DOI: 10.1007/s43390-020-00171-9] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/23/2020] [Accepted: 07/20/2020] [Indexed: 10/23/2022]
Abstract
BACKGROUND CONTEXT Preoperative (pre-op) identification of patients likely to achieve a clinically meaningful improvement following surgery for adult spinal deformity (ASD) is critical, especially given the substantial cost and comorbidity associated with surgery. Even though pain is a known indication for surgical ASD correction, we are not aware of established thresholds for baseline pain and function to guide which patients have a higher likelihood of improvement with corrective surgery. PURPOSE We aimed to establish pre-op patient-reported outcome measure (PROM) thresholds to identify patients likely to improve by at least one minimum clinically important difference (MCID) with surgery for ASD. STUDY DESIGN This is a retrospective cohort study using prospectively collected data. PATIENT SAMPLE We reviewed 172 adult patients' charts who underwent corrective surgery for spinal deformity. OUTCOME MEASURES Included measures were the Visual Analog Scale for pain (VAS), Oswestry Disability Index (ODI), and Scoliosis Research Society-22 (SRS-22). Our primary outcome of interest was improvement by at least one MCID on the ODI and SRS-22 at 2 years after surgery. METHODS As part of usual care, the VAS, ODI, and SRS-22 were collected pre-op and re-administered at 1, 2, and 5 years after surgery. MCIDs were calculated using a distribution-based method. Determining significant predictors of MCID at two years was accomplished by Firth bias corrected logistic regression models. Significance of predictors was determined by Profile Likelihood Chi-square. We performed a Youden analysis to determine thresholds for the strongest pre-op predictors. RESULTS At year two, 118 patients (83%) reached MCID for the SRS and 127 (75%) for the ODI. Lower pre-op SRS overall, lower pre-op SRS pain, and higher pre-op SRS function predicted a higher likelihood of reaching MCID on the overall SRS (p < 0.05). Higher pre-op ODI, lower SRS pain and self-image, and higher SRS overall predicted a higher likelihood of reaching MCID on the ODI (p < 0.05). An ODI threshold of 29 predicted reaching MCID with a sensitivity of 0.89 and a specificity of 0.64 (AUC = 0.7813). An SRS threshold of 3.89 predicted reaching MCID with a sensitivity of 0.93 and specificity of 0.68 (AUC = 0.8024). CONCLUSIONS We identified useful thresholds for ODI and SRS-22 with acceptable predictive ability for improvement with surgery for ASD. Pre-op ODI, SRS, and multiple SRS subscores are predictive of meaningful improvement on the ODI and/or SRS at 2 years following corrective surgery for spinal deformity. These results highlight the usefulness of PROMs in pre-op shared decision-making.

Abstract
INTRODUCTION Adolescent idiopathic scoliosis (AIS) is a three-dimensional deformity of the spine. Brace treatment is effective for eligible patients with AIS and the effectiveness is significantly correlated with the average brace-wear time per day. Three-dimensional (3D) printing technology is a recent advancement that offers unique opportunities for biomedical applications, and customisation of scoliosis braces might lead to greater patient satisfaction and improved compliance. We present here the design of a randomised controlled trial on the clinical effectiveness of 3D-printed braces versus thoracolumbosacral orthoses (TLSO) for patients with AIS. METHODS AND ANALYSIS Patients with AIS (age 10-16 years) with Risser sign 0-II, Cobb angle of main curve of 20°-40°, premenarchal or no more than 1-year postmenarchal (for women), and no history of treatment are eligible, unless they are unable to tolerate the treatment or refuse participation. A total of 88 patients will be randomised into either the 3D group or TLSO group on a 1:1 basis. Participants in the 3D group will choose between a 3D-printed brace and TLSO, according to the Zelen's design of the trial. Primary outcome measures will include the average brace-wear time per day, health-related quality of life and Cobb angle progression of the primary curve. Secondary outcome measures will include immediate in-brace correction of Cobb angle of the primary curve, rate of conversion to surgery and incidence of any adverse events. This study is designed as a single-centre, two-arm, superiority and open-label randomised controlled trial. The sample size is calculated with reference to the preliminary study and based on the sample size calculation formula. ETHICS AND DISSEMINATION This study was approved by the Peking University Third Hospital Medicine Science Research Ethics Committee (No: 2019-017-02). Results of the trial will be submitted for publication in a peer-reviewed journal and as conference presentations. TRIAL REGISTRATION NUMBER ChiCTR1900027379, pre-results.

Abstract
STUDY DESIGN Cross-sectional, observational. OBJECTIVES (i) To develop a cross-culturally adapted Hindi translation of the Scoliosis Research Society (SRS)-22r (refined) questionnaire and (ii) validate it in Hindi-speaking Indian patients with adolescent idiopathic scoliosis (AIS). BACKGROUND DATA Health-related quality of life (HRQoL)-based questionnaires have superseded objective clinical and radiological measurements as tools to assess the outcome of health-related interventions. The SRS-22r is an extensively validated HRQoL-based questionnaire for AIS patients and has been adapted and translated in other languages. METHODOLOGY A Hindi version of SRS-22r was developed in accordance with standard guidelines for cross-cultural adaptation. The final Hindi version was administered to 108 AIS patients. Subsequently, 58/108 patients answered the Hindi version again after 10-14 days. Another 50/108 bilingual patients answered the original English version after 10-14 days. In addition, 52/108 patients answered a previously validated Hindi version of Short Form (SF)-36 health survey. Content analysis, floor/ceiling effects, internal consistency, test/retest reproducibility and concurrent validity with the English version and the SF-36 questionnaire were determined for the Hindi version of SRS-22r. RESULTS High ceiling effect was noted for the pain and satisfaction with management domains of Hindi version of SRS-22r. Overall internal consistency was good (Cronbach α = 0.77)-all domains, except the function domain (α = 0.61) had good or excellent internal consistency. The test/retest reliability for all domains was excellent (intraclass coefficient/ICC > 0.80). The concurrent validity with the English version showed an excellent correlation for all domains (ICC > 0.80). Concurrent validity with SF-36 showed good correlation between relevant domains of SRS-22r and SF-36, except for the self-image and satisfaction with management domains of SRS-22r. CONCLUSION Based on the results proving its reliability and validity, the adapted Hindi version of SRS-22r can be effectively used in Hindi-speaking, Indian AIS patients. LEVEL OF EVIDENCE 3.

Abstract
OBJECTIVE Although it is well known that major curve severity in adolescent idiopathic scoliosis (AIS) is inversely related to self-image, surgeons often encounter patients who complain of low self-image with preoperatively mild curves or postoperatively well-corrected main curves, suggesting the presence of other factors. This study examined factors contributing to self-image in AIS. METHODS A total of 86 consecutive patients who underwent posterior spinal fusion for AIS Lenke 1 or 2 curves and were followed for a minimum of 2 years were included in this study of patient self-image based on data that included scores reported on the Scoliosis Research Society survey (SRS-22r). The authors evaluated sex, BMI, Risser grade, age, angle of trunk rotation, Cobb angle of the main thoracic (MT) curve, Cobb angle of the thoracolumbar/lumbar (TL/L) curve, apical vertebral translation (AVT), T5-12 kyphotic angle, and clavicular angle. Univariate and multivariate general linear models were employed to identify preoperative and 2-year postoperative factors that impact self-image. RESULTS Univariate analysis revealed no significant correlation between preoperative MT curve Cobb angle and SRS-22r self-image score (p = 0.51), although patients with a higher MT curve AVT had a significantly worse preoperative self-image (p < 0.01). Two years postoperatively, larger Cobb angle of the TL/L curve (p = 0.01) and higher Risser grade (p = 0.03) resulted in significantly lower self-image scores. In multivariate testing, preoperative MT curve AVT remained significantly related to diminished self-image (p < 0.01). Two years later, higher TL/L curve (p < 0.01), Risser grade (p = 0.03), and MT curve AVT (p = 0.03) had significant associations with lower self-image scores. CONCLUSIONS Preoperative MT curve AVT appears more strongly related to self-image than does Cobb angle. Two years postoperatively, persistent TL/L region curvature and high Risser grade may also be associated with diminished patient self-image.

Abstract
INTRODUCTION Physical functioning (PF) is the ability to carry out the physical activity of daily living. It is an important outcome that provides a meaningful evaluation of individuals' life. PF can be assessed using patient-reported outcome measures, performance-based outcome measures or body structure and function measure. Measures need to be valid, reliable and responsive to change to evaluate the effects of an intervention. Adolescent idiopathic scoliosis (AIS) is the most common deformity among the paediatric population and impacts on individuals' lives. This systematic review will appraise evidence on the measurement properties of PF tools in individuals with AIS. METHODS/ANALYSIS A protocol for systematic review and meta-analysis informed by Cochrane guidelines is reported in line with Preferred Reporting Items for Systematic Reviews and Meta-Analysis-P. MEDLINE, PsycINFO, EMBASE, CINAHL, SPORTdiscus, Web of Science and PubMed will be searched in two stages, from inception until December 2019. Search 1 will inventory all studies that assessed PF in participants with AIS, without any limitations. The search terms will be scoliosis, adolescent and PF-related terms. Search 2 will include studies which investigated instrument measurement properties in the same population for measures identified in search one. Two reviewers will independently perform study selection, data extraction, risk of bias and overall quality assessment. The COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) risk of bias and a modified Grading of Recommendations, Assessment, Development and Evaluation (GRADE) guidelines will be used. A meta-analysis will be conducted if possible, or the evidence will be synthesised and summarised per measurement property per outcome measure per measurement type. ETHICS AND DISSEMINATION This review will provide recommendations for practice and future research, considering psychometric properties of outcome measures of PF in AIS. The results of this study will be disseminated through a peer-reviewed publication and conference presentation. PROSPERO REGISTRATION NUMBER CRD42019142335.

Abstract
BACKGROUND Aesthetics is recognized as a main outcome in idiopathic scoliosis (IS) treatment, but to date, there is no criterion standard for physicians' evaluation. Trunk Aesthetic Clinical Evaluation (TRACE) is a simple 12-point ordinal scale to quantify symmetry as a proxy of aesthetics. TRACE is already diffused worldwide and has been used in clinical research. OBJECTIVE We aimed to validate TRACE and improve it with Rasch analysis. MATERIAL AND METHODS This study involved an observational Rasch analysis validation of an evaluation tool in outpatient rehabilitation centres. From a clinical database, we randomly selected patients who had IS, were age 10 to 18, had brace prescription at first evaluation, and had at least 2 consultations. Rasch analysis (partial credit model) was used. Differential item functioning (DIF) was assessed for age, sex, disease severity, bracing and treatment. The median was chosen to dichotomize disease severity and bracing. We removed 64 outlier participants (4%). RESULTS We included 1553 participants (1334 females; mean [SD] age 13 [1.7] years old). TRACE items showed ordered thresholds and proper fit to the Rasch model. The score-to-measure conversion table showed proper length (range -4.55 to 4.79 logit) with a mean (SE) measure of -0.52 (0.04) logit. The principal component analysis supported the TRACE unidimensionality. The TRACE was free from DIF for age, sex and bracing. CONCLUSIONS The TRACE ordinal scale has been converted into a Rasch-consistent, interval-level measure of trunk aesthetics in IS patients and can be used to compare different populations. Its main flaw is low reliability, likely because of the small number of items. TRACE can be used as an outcome measure and in everyday clinical evaluation of IS, even if new developments of the scale are advised.

Abstract
STUDY DESIGN This was a correlational study. OBJECTIVE Determine the range of pediatric Patient-Reported Outcomes Measurement Information System (PROMIS) scores for patients treated for adolescent idiopathic scoliosis (AIS) and assess correlation with Scoliosis Research Society-22 (SRS-22) domain scores. SUMMARY OF BACKGROUND DATA Patient reported outcome (PRO) measures are important metrics for measuring health status in diverse patient populations. PROMIS is increasingly being used in orthopedic practice. Existing literature compares PROMIS measures favorably to legacy measures in numerous adult orthopedic conditions. This study sought to define the range of PROMIS mobility, pain interference, and peer relationships scores for adolescents treated for AIS. Furthermore, correlations between these domains and equivalent domains in the legacy PRO, SRS-22, were determined. METHODS Pediatric PROMIS and SRS-22 were obtained at routine clinical visits for AIS at a tertiary care children's hospital from January 2017 to October 2017. Spearman correlations were performed to examine the associations between three pediatric PROMIS domains and the SRS-22 domains. Only patients who completed both PRO measures were included in the analyses. Radiographic measurements were performed at each visit assessing sagittal and coronal deformity and overall spinal balance. RESULTS One hundred thirteen patients with a mean age of 14.4 (standard deviation [SD] = 2.1) years completed the assessments. The mean pediatric PROMIS domain scores included: mobility 50.9 (interquartile range [IQR] 36.2-65.6); pain interference 45.9 (IQR 28.9-62.9); peer relations 52.6 (IQR 38.3-64.9).PROMIS mobility was strongly correlated with SRS-22 function (r = 0.65; P < 0.001). PROMIS pain interference was strongly correlated with SRS-22 pain (r = 0.70; P < 0.001). PROMIS peer relations was moderately correlated with SRS-22 Mental Health (r = 0.41; P < 0.001) and self-image (r = 0.34; P < 0.001). CONCLUSION In AIS patients pediatric PROMIS pain interference and mobility correlate strongly with SRS-22 pain and function domains, while PROMIS peer relationships demonstrates moderate correlations with SRS-22 mental health and self-image.

Abstract
BACKGROUND Adult spinal deformity (ASD) is a complex entity that has had emerging significance for spine surgeons in the last decade. Sagittal and/or coronary deformities can have a high impact (disability, pain) on the quality of patients' life. Radiologic diagnostics determine the common spinopelvic parameters as the basis for classification of ASD. TREATMENT Conservative treatment options may be sufficient in mild cases. The deformity's complexity frequently demands the entire spectrum of methods and techniques in spinal surgery. This article gives an overview on the development of the ASD, the correct classification as well as the indication for surgical therapy.

Abstract
BACKGROUNDS Adolescent idiopathic scoliosis (AIS) is an adolescent onset spinal deformity, which can negatively affect the mental health of these patients. But no studies about their parental mental health have been reported so far. In this study, the parental mental health of AIS patients and the associated risk factors were evaluated by a cross-sectional survey. METHODS 64 AIS patients who underwent conservative or surgical treatments in our hospital from April 2017 to March 2018, and their parents were enrolled in the AIS group. 85 parents of healthy children were enrolled in the control group. Depression and anxiety were separately assessed using the Patient Health Questionnaire (PHQ-9) and the Generalized Anxiety Disorder 7-item scale (GAD-7). Spearman correlation coefficients were first estimated to investigate the relationships among the parental PHQ-9/GAD-7 scores and the patient's PHQ-9/GAD-7 scores in the AIS group. Then, the morbidities of the parental probable major depressive disorder (pMDD, PHQ score ≥ 10) and probable general anxiety disorder (pGAD, GAD-7 score ≥ 10) were compared between the AIS and control groups. Third, the potential risk factors for parental pMDD or pGAD in the AIS group were compared using the chi-squared test or Student's t-test, respectively. Finally, the uneven distributive variates were analyzed using the binary logistic regression model. RESULTS Both parental depression and anxiety were moderately associated with those of the patients (r = 0.448~0.515, p < 0.01) in the AIS group, respectively. The morbidities of parental pMDD and pGAD in the AIS group were 14.1%, significantly higher than those in the control group (pMDD = 4.7%, p = 0.045; pGAD = 3.5%, p = 0.019). A Cobb angle of the major curve ≥50° (p = 0.034, odds ratio [OR] = 8.264), patients with pMDD (p = 0.018, OR = 17.576), and low education level of the parents (p = 0.026, OR = 0.122) were the risk factors of parental pMDD. Household income < 8000 rmb/month was the risk factor for parental pGAD (p = 0.021). CONCLUSIONS The morbidities of pMDD and pGAD in parents of AIS patients were higher than those in parents of healthy children. Parental depression and anxiety were closely associated with their children's depression and anxiety. Therefore, the parental mental health of AIS patients should be paid attention to, especially for those parents with risk factors.

Abstract
Background Hyperkyphosis is common among older adults and is associated with multiple adverse health outcomes. Kyphosis-specific exercise and posture training programs improve hyperkyphosis, but in-person programs are expensive to implement and maintain over long periods. It is unclear if a technology-based posture training program disseminated through a mobile phone is a feasible or acceptable alternative to in-person training among older adults with hyperkyphosis. Objective The primary purpose was to assess the feasibility of subject recruitment, short-term retention and adherence, and acceptability of a technology-based exercise and posture training program disseminated as video clip links and text messaging prompts via a mobile phone. The secondary purpose was to explore the potential efficacy of this program for kyphosis, physical function, and health-related quality of life in older adults with hyperkyphosis. Methods In this 6-week pre-post design pilot trial, we recruited community-dwelling adults aged ≥65 years with hyperkyphosis ≥40° (±5°) and access to a mobile phone. The intervention had two parts: (1) exercise and posture training via video clips sent to participants daily via text messaging, including 6 weekly video clip links to be viewed on the participant’s mobile phone, and (2) text messaging prompts to practice good posture. We analyzed the subject recruitment, adherence, retention, and acceptability of the intervention. Outcomes included change in kyphometer-measured kyphosis, occiput-to-wall (OTW) distance, Short Physical Performance Battery score, Scoliosis Research Society (SRS-30) score, Center for Epidemiological Studies Depression score, and Physical Activity Scale for the Elderly (PASE) score. Results A total of 64 potential participants were recruited, 17 were enrolled, and 12 completed postintervention testing at 6 weeks. The average age was 71.6 (SD 4.9) years, and 50% were women. The median adherence to daily video viewing was 100% (range, 14%-100%) and to practicing good posture at least three times per day was 71% (range, 0%-100%). Qualitative evaluation of intervention acceptability revealed that the mobile phone screen was too small for participants to view the videos well and daily prompts to practice posture were too frequent. Kyphosis, OTW distance, and physical activity significantly improved after the 6-week intervention. Kyphosis decreased by 8° (95% CI –12 to –5; P<.001), OTW decreased by 1.9 cm (95% CI –3.3 to –0.7; P=.007), and physical activity measured by PASE increased by 29 points (95% CI 3 to 54; P=.03). The health-related quality of life SRS-30 score increased by 0.11 point (SD 0.19), but this increase was not statistically significant (P=.09). Conclusions Technology-based exercise and posture training using video clip viewing and text messaging reminders is feasible and acceptable for a small cohort of older adults with hyperkyphosis. Technology-based exercise and posture training warrants further study as a potential self-management program for age-related hyperkyphosis, which may be more easily disseminated than in-person training.

Abstract
STUDY DESIGN A cross-cultural adaptation and reliability study. OBJECTIVE To perform cross-cultural adaptation and evaluate the reliability and validity of the Hebrew version of the Scoliosis Research Society-22 (SRS-22) questionnaire. SUMMARY OF BACKGROUND DATA The SRS-22 validated in different languages is used in assessing health-related quality of life of patients with scoliosis. METHODS The English SRS-22 was translated/retranslated and a cross-cultural adaptation was performed. The Hebrew SRS-22 was administered twice, a week apart, to 45 patients with idiopathic scoliosis and 15 with Scheuermann kyphosis. The Cobb angle of the thoracic curvature, the numeric rating scale (NRS) of pain and of the self-perceived cosmetic defect, were evaluated. Internal consistency was determined by the Cronbach α coefficient. Intraclass correlation was used for test-retest reliability. Concurrent validity of the SRS-22 domains with the Cobb angle, NRS pain, and NRS cosmetic defect was evaluated by Pearson correlation. RESULTS The mean age of the subjects was 17.3 ± 7.42 years. The Cobb angle was 39.43 ± 17.52, NRS pain during the last 24 hours was 4.35 ± 3.42, and the NRS cosmetic defect was 3.80 ± 3.57. The mean overall Cronbach α of the Hebrew SRS-22 was 0.75. Two domains, function/activity (α = 0.63) and satisfaction (α = 0.66), showed a questionable internal consistency, self-image (α = 0.72) showed acceptable, pain (α = 0.80) good, and mental health (α = 0.92) excellent internal consistency. The intraclass correlation for five domains ranged from 0.71 to 0.95, demonstrating good test-retest reproducibility. The concurrent validity of the SRS-22 in scoliosis subjects with the Cobb angle was moderate (r = 0.37), and with NRS pain (r = 0.62) and NRS cosmetic defect (r = 0.54) good. In kyphosis subjects, the only significant high correlation was found between the self-image domain of SRS-22 and the NRS cosmetic defect (r = 0.84). CONCLUSION The Hebrew version of the SRS-22 can be used to assess the outcome of treatment among Hebrew-speaking patients with idiopathic scoliosis and Scheuermann disease. LEVEL OF EVIDENCE Level 2.

Abstract
STUDY DESIGN Retrospective review of prospectively collected data. OBJECTIVE To determine whether adolescent idiopathic scoliosis (AIS) patients with active complications at two-year follow-up demonstrate lower Scoliosis Research Society (SRS-22) questionnaire scores. SUMMARY OF BACKGROUND DATA There is limited evidence as to whether the SRS-22 is sensitive to complications in postoperative AIS patients. METHODS Surgical patients with SRS-22 scores completed at two-year follow-up were included. Five groups were created: no complication, minor complication resolved by 2 years, major complication resolved by 2 years, minor complication active, and major complication active at 2 years. Likelihood of reaching a minimal clinically important difference (MCID) for pain (0.20) and self-image (0.98) was evaluated. RESULTS 1,481 patients were identified. Major complications active at two years existed in 2.2% of patients. These patients had the lowest score in all domains and total scores (p < .05). If a minor complication was active, scores were impacted for pain, self-image, satisfaction, and total (p < .05). No differences were found between no complication and resolved complications. Patients with active major complications were more likely to have a pain score that worsened from pre- to two years reaching MCID (52%) compared to the other four groups (range 18%-29%, odds ratio [OR] 3.6, p < .001). They also had a nonsignificant decreased rate of improvement of self-image score at an MCID level (42% vs. range 51%-66%, OR 0.56, p = .10). CONCLUSIONS When timing is considered, the SRS-22 demonstrates the ability to discriminate between patients with and without a complication. Active experience of a major complication impacted SRS-22 scores, in particular, the rate of worsening scores for pain, self-image, function, and total score. LEVEL OF EVIDENCE Level III.

Abstract
BACKGROUND Idiopathic scoliosis is the most common type of spinal deformity. Scoliosis is defined as a lateral curvature of the spine greater than 10° accompanied by rotation of the vertebrae. The treatment available for adolescent idiopathic scoliosis is observation, orthosis, and surgery. The surgical options include open anterior release and instrumentation, posterior instrumentation, and thoracoscopic approaches. The Scoliosis Research Society Questionnaire (SRS-30) is a specific instrument to measure health-related quality of life in patients with scoliosis, who had or had not undergone surgery. The purpose was to assess the post-operative functional outcome using SRS-30 in children who underwent anterior release, instrumentation, and fusion using autogenous rib graft for adolescent idiopathic scoliosis (AIS). METHODS In a retrospective cohort study, 25 patients between the ages of 11 and 17 years, who underwent anterior release, instrumentation, and fusion using autogenous rib graft for adolescent idiopathic scoliosis (AIS) between 2008 and 2014, were included in the study. RESULTS The total average score was 4.26 with a SD of 0.014 and had maximum average score 4.5 (for pain) and minimum average score 3.8 (for self-image). CONCLUSION Anterior release, instrumentation, and fusion using autogenous rib graft is having good functional outcome in all domains.

Abstract
STUDY DESIGN Retrospective review of North American and Japanese adult spinal deformity (ASD) database. OBJECTIVE To investigate the ethnical differences in radiographic parameters and Scoliosis Research Society (SRS)-22 between North American and Japanese ASD. SUMMARY OF BACKGROUND DATA Previous comparison study between North American and Japanese ASD patients has revealed Japanese patients had marked pelvic tilt deformity and had lower Oswestry Disability Index scores corresponding to established thresholds of radiographic deformity. However, the subjects of the previous study included relatively younger ASD patients (above 18 y) of idiopathic origin. MATERIALS AND METHODS Total 282 ASD patients older than 50 years, 211 patients from North America (United States) and 71 patients from Japan (JP), with minimum 2-year follow-up postoperatively were included in the study. Radiologic parameters were compared at the baseline and at 2-year follow-up. SRS-22 score was used for the comparison of clinical outcome. RESULTS At baseline, Japan showed significantly worse sagittal alignment such as smaller lumbar lordosis (LL), larger pelvic incidence (PI), and larger sagittal vertical axis than United States. However, Japan had significantly fewer levels fused than United States (US, 12.66±4.6; JP, 8.49±2.7). At 2 years after the surgery, Japan still had significantly worse residual sagittal deformity. Comparison of SRS-22 scores revealed Japan had better pain but worse functional domain scores at baseline which improved to comparable levels to the United States at 2 years. Self-image and mental health scores in Japan were significantly worse both at baseline and at 2 years. Analysis of factors affecting SRS-22 satisfaction score at 2 years revealed that previous spinal fusion surgery in the United States and LL, PI-LL, and sagittal vertical axis at 2 years in Japan had significant correlation. CONCLUSIONS These similarities and discrepancies may be influenced by the cultural or lifestyle differences between both nations and should be considered when interpreting the results of ASD studies among different ethnicities.

Abstract
STUDY DESIGN Retrospective cohort. OBJECTIVE To examine Charlson Comorbidity Index (CCMI) as a marker for deterioration in health status not reflected in standard Health Related Quality of Life (HRQOL) measures. SUMMARY OF BACKGROUND DATA HRQOL has become a primary metric for assessing outcomes following spinal deformity surgery. However, studies have reported limited impact of complications on postoperative HRQOL outcomes. METHODS We examined serial CCMI, complications, and HRQOL outcomes for 138 adult lumbar deformity patients treated surgically with a minimum two-year follow-up that included 126 females (91%) with a mean age of 59.8 years (range, 40.2-78.5). Patients with no, minor, or major complications were compared at baseline and at one and two years postoperation. RESULTS Minor complications were observed in 26 patients (19%) and major complications in 15 (11%). Major complications included motor deficit (7), deep vein thrombosis (4), and respiratory failure (3). There was no difference in preoperative SF-36 Physical Component Summary or Scoliosis Research Society-22R (SRS-22R) scores among the groups at baseline. Preoperative CCMI was lowest in the No Complication group (3.52 ± 1.70) followed by the Major (4.00 ± 1.13) and Minor Complication groups (4.15 ± 1.71, p = .165). At one year, there was a significantly greater CCMI deterioration in the Major Complication group (0.80 ± 1.01) compared to both the Minor (0.08 ± 0.27) and No Complication groups (0.27 ± 0.47, p < .001). There was no significant difference in SF-36 Physical Component Summary or SRS-22R scores among the three groups. Similar findings were observed at two years. CONCLUSIONS Despite similar one- and two-year HRQOL improvement, patients with major complications had greater deterioration in CCMI. As CCMI is predictive of medical and surgical risk, patients who sustained a major complication now carry a greater likelihood of adverse outcomes with future interventions, including any subsequent spinal surgery. Although this increased risk may not alter the patient's perception of his or her current health status, it may be important, and should be recognized as part of the shared decision-making process. LEVEL OF EVIDENCE Level II, high-quality prognostic study.

Abstract
BACKGROUND Hyperkyphosis, an excessive anterior curvature in the thoracic spine, is associated with reduced health status in older adults. Hyperkyphosis is highly prevalent, more common in older women than men. There is no standard intervention to reduce age-related hyperkyphosis. Sex differences in response to a kyphosis-specific exercise intervention are not known. METHODS We conducted a randomized controlled trial of a targeted kyphosis-specific exercise and postural training program on the primary outcome Cobb angle of kyphosis, and investigated whether the magnitude of change differed between men and women. One hundred twelve participants aged ≥60 years with kyphosis ≥40° were enrolled and randomized to exercise or waitlist control, and 101 participants had analyzable baseline and follow-up radiographs for Cobb angle measurements. A group intervention including 10 participants per group was delivered by a physical therapist, 1-h, twice a week for 3-months. Controls were placed on a waitlist for 3 months before receiving a delayed intervention. Primary outcome was change from baseline to 3-months in Cobb angle measured from standing lateral spine radiographs. Secondary outcomes included change over 3-months in kyphometer-measured kyphosis, physical function and quality of life. Groups were combined for analysis after both received the intervention, and sex differences in response to the intervention were tested with ANOVA. RESULTS Participants (60 women, 41 men) were 70.0 (SD = 5.7) years old with mean Cobb angle 55.9 (SD = 12.2) degrees at baseline. The active group had higher baseline modified Physical Performance Test scores than control, p = 0.03. Men had greater baseline kyphometer-measured kyphosis, p = 0.09, and higher bone mineral density (BMD), spine strength, more vertebral fractures and diffuse idiopathic skeletal hyperostosis (DISH) than women, p ≤ 0.01. There was no statistically significant difference between groups in change in Cobb at 3-months, p = 0.09, however change in kyphometer-measured kyphosis differed by 4.8 (95% CI:-6.8,-2.7) degrees, p < 0.001, favoring the active group. There were no differences between men and women in change in either kyphosis measurement after intervention, p > 0.1. CONCLUSIONS A 3-month targeted spine strengthening exercise and posture training program reduced kyphometer-measured, but not radiographic-measured kyphosis. Despite sex differences in baseline kyphosis, BMD, spine strength, fractures and DISH, sex did not affect treatment response. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT01766674.

Abstract
OBJECTIVEThe subtraction of lumbar lordosis (LL) from the pelvic incidence (PI) offers an estimate of the LL required for a given PI value. Relative LL (RLL) and the lordosis distribution index (LDI) are PI-based individualized measures. RLL quantifies the magnitude of lordosis relative to the ideal lordosis as defined by the magnitude of PI. LDI defines the magnitude of lower arc lordosis in proportion to total lordosis. The aim of this study was to compare RLL and PI − LL for their ability to predict postoperative complications and their correlations with health-related quality of life (HRQOL) scores.METHODSInclusion criteria were ≥ 4 levels of fusion and ≥ 2 years of follow-up. Mechanical complications were proximal junctional kyphosis/proximal junctional failure, distal junctional kyphosis/distal junctional failure, rod breakage, and implant-related complications. Correlations between PI − LL, RLL, PI, and HRQOL were analyzed using the Pearson correlation coefficient. Mechanical complication rates in PI − LL, RLL, LDI, RLL, and LDI interpreted together, and RLL subgroups for each PI − LL category were compared using chi-square tests and the exact test. Predictive models for mechanical complications with RLL and PI − LL were analyzed using binomial logistic regressions.RESULTSTwo hundred twenty-two patients (168 women, 54 men) were included. The mean age was 52.2 ± 19.3 years (range 18–84 years). The mean follow-up was 28.8 ± 8.2 months (range 24–62 months). There was a significant correlation between PI − LL and PI (r = 0.441, p < 0.001), threatening the use of PI − LL to quantify spinopelvic mismatch for different PI values. RLL was not correlated with PI (r = −0.093, p > 0.05); therefore, it was able to quantify divergence from ideal lordosis for all PI values. Compared with PI − LL, RLL had stronger correlations with HRQOL scores (p < 0.05). Discrimination performance was better for the model with RLL than for PI − LL. The agreement between RLL and PI − LL was high (κ = 0.943, p < 0.001), moderate (κ = 0.455, p < 0.001), and poor (κ = −0.154, p = 0.343), respectively, for large, average, and small PI sizes. When analyzed by RLL, each PI − LL category was further divided into distinct groups of patients who had different mechanical complication rates (p < 0.001).CONCLUSIONSUsing the formula of PI − LL may be insufficient to quantify normolordosis for the whole spectrum of PI values when applied as an absolute numeric value in conjunction with previously reported population-based average thresholds of 10° and 20°. Schwab PI − LL groups were found to constitute an inhomogeneous group of patients. RLL offers an individualized quantification of LL for all PI sizes. Compared with PI − LL, RLL showed a greater association with both mechanical complications and HRQOL. The use of RLL and LDI together, instead of PI − LL, for surgical planning may result in lower mechanical complication rates and better long-term HRQOL.

Adolescent Idiopathic Scoliosis Surgery by a Neurosurgeon: Learning Curve for Neurosurgeons. World Neurosurg 2017; 110:e129-e134. [PMID: 29107722 DOI: 10.1016/j.wneu.2017.10.109] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2017] [Revised: 10/18/2017] [Accepted: 10/20/2017] [Indexed: 11/24/2022]
Abstract
OBJECTIVE To determine a neurosurgeon's learning curve of surgical treatment for adolescent idiopathic scoliosis (AIS) patients. METHODS This study is a retrospective analysis. Forty-six patients were treated by a single neurosurgeon between 2011 and 2017 using posterior segmental instrumentation and fusion. According to the time period, the former and latter 23 patients were divided into group 1 and group 2, respectively. Patients' demographic data, curve magnitude, number of levels treated, amount of correction achieved, radiographic/clinical outcomes, and complications were compared between the groups. RESULTS The majority were females (34 vs. 12) with average ages of 15.0 versus 15.6, respectively. The mean follow-up period was 24.6 months. The average number of fusion levels was similar with 10.3 and 11.5 vertebral bodies in groups 1 and 2, respectively. The average Cobb angle of major curvature was 59.8° and 58.5° in groups 1 and 2, respectively. There observed significant reductions of operative time (324.4 vs. 224.7 minutes, P = 0.007) and estimated blood loss (648.3 vs. 438.0 mL, P = 0.027) in group 2. The correction rate of the major structural curve was greater in group 2 (70.7% vs. 81.0%, P = 0.001). There was no case of neurologic deficit, infection, and revision for screw malposition. One patient of group 1 underwent fusion extension surgery for shoulder asymmetry. CONCLUSION Radiographic and clinical outcomes of AIS patients treated by a neurosurgeon were acceptable. AIS surgery may be performed with an acceptable rate of complications after about 20 surgeries. With acquisition of surgical experiences, neurosurgeons could perform deformity surgery for AIS effectively and safely.

Targeted spine strengthening exercise and posture training program to reduce hyperkyphosis in older adults: results from the study of hyperkyphosis, exercise, and function (SHEAF) randomized controlled trial. Osteoporos Int 2017; 28:2831-2841. [PMID: 28689306 PMCID: PMC5873977 DOI: 10.1007/s00198-017-4109-x] [Citation(s) in RCA: 62] [Impact Index Per Article: 8.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/10/2017] [Accepted: 05/31/2017] [Indexed: 01/01/2023]
Abstract
A 6-month randomized controlled trial of spine-strengthening exercise and posture training reduced both radiographic and clinical measures of kyphosis. Participants receiving the intervention improved self-image and satisfaction with their appearance. Results suggest that spine-strengthening exercise and postural training may be an effective treatment option for older adults with hyperkyphosis. INTRODUCTION The purpose of the present study is to determine in a randomized controlled trial whether spine-strengthening exercises improve Cobb angle of kyphosis in community-dwelling older adults. METHODS We recruited adults ≥60 years with kyphosis ≥40° and enrolled 99 participants (71 women, 28 men), mean age 70.6 ± 0.6 years, range 60-88, with baseline Cobb angle 57.4 ± 12.5°. The intervention included group spine-strengthening exercise and postural training, delivered by a physical therapist, 1-h, three times weekly for 6 months. Controls received four group health education meetings. The primary outcome was change in the gold standard Cobb angle of kyphosis measured from standing lateral spine radiographs. Secondary outcomes included change in kyphometer-measured kyphosis, physical function (modified Physical Performance Test, gait speed, Timed Up and Go, Timed Loaded Standing, 6-Min Walk), and health-related quality of life (HRQoL) (PROMIS global health and physical function indexes, SRS-30 self-image domain). ANCOVA was used to assess treatment effects on change from baseline to 6 months in all outcomes. RESULTS There was a -3.0° (95% CI -5.2, -0.8) between-group difference in change in Cobb angle, p = 0.009, favoring the intervention and approximating the magnitude of change from an incident vertebral fracture. Kyphometer-measured kyphosis (p = 0.03) and SRS-30 self-esteem (p < 0.001) showed favorable between-group differences in change, with no group differences in physical function or additional HRQoL outcomes, p > 0.05. CONCLUSIONS Spine-strengthening exercise and posture training over 6 months reduced kyphosis compared to control. Our randomized controlled trial results suggest that a targeted kyphosis-specific exercise program may be an effective treatment option for older adults with hyperkyphosis.

Factor analysis of the SRS-22 outcome assessment instrument in patients with adult spinal deformity. EUROPEAN SPINE JOURNAL : OFFICIAL PUBLICATION OF THE EUROPEAN SPINE SOCIETY, THE EUROPEAN SPINAL DEFORMITY SOCIETY, AND THE EUROPEAN SECTION OF THE CERVICAL SPINE RESEARCH SOCIETY 2017; 27:685-699.

Abstract
PURPOSE Designed for patients with adolescent idiopathic scoliosis, the SRS-22 is now widely used as an outcome instrument in patients with adult spinal deformity (ASD). No studies have confirmed the four-factor structure (pain, function, self-image, mental health) of the SRS-22 in ASD and under different contexts. Factorial invariance of an instrument over time and in different languages is essential to allow for precise interpretations of treatment success and comparisons across studies. This study sought to evaluate the invariance of the SRS-22 structure across different languages and sub-groups of ASD patients. METHODS Confirmatory factor analysis was performed on the 20 non-management items of the SRS-22 with data from 245 American English-, 428 Spanish-, 229 Turkish-, 95 French-, and 195 German-speaking patients. Item loading invariance was compared across languages, age groups, etiologies, treatment groups, and assessment times. A separate sample of SRS-22 data from 772 American surgical patients with ASD was used for cross-validation. RESULTS The factor structure fitted significantly better to the proposed four-factor solution than to a unifactorial solution. However, items 14 (personal relationships), 15 (financial difficulties), and 17 (days off work) consistently showed weak item loading within their factors across all language versions and in both baseline and follow-up datasets. A trimmed SRS (16 non-management items) that used the four least problematic items in each of the four domains yielded better-fitting models across all languages, but equivalence was still not reached. With this shorter version there was equivalence of item loading with respect to treatment (surgery vs conservative), time of assessment (baseline vs 12 months follow-up), and etiology (degenerative vs idiopathic), but not age (< vs ≥50 years). All findings were confirmed in the cross-validation sample. CONCLUSION We recommend removal of the worst-fitting items from each of the four domains of the SRS-instrument (items 3, 14, 15, 17), together with adaptation and standardization of other items across language versions, to provide an improved version of the instrument with just 16 non-management items.

Abstract
STUDY DESIGN Prospective validation of the Scoliosis Research Society Outcomes Questionnaire French-Canadian version (SRS-22fv) in adolescent patients with spondylolisthesis. OBJECTIVE To determine the measurement properties of the SRS-22fv. SUMMARY OF BACKGROUND DATA The SRS-22 is widely used for the assessment of health-related quality of life in adolescent idiopathic scoliosis (AIS) and other spinal deformities. Spondylolisthesis has an important effect on quality of life. The instrument was previously used in this population, although its measurement properties remained unknown. We aim to determine its reliability, factorial, concurrent validity, and its discriminant capacity in an adolescent spondylolisthesis population. METHODS The SRS-22fv was tested in 479 subjects (272 patients with spondylolisthesis, 143 with AIS, and 64 controls) at a single institution. Its reliability was measured using the coefficient of internal consistency, concurrent validity by the short form-12 (SF-12v2 French version) and discriminant validity using multivariate analysis of variance, analysis of covariance, and multivariate linear regression. RESULTS The SRS-22fv showed a good global internal consistency (spondylolisthesis: Cronbach α = 0.91, AIS: 0.86, and controls: 0.78) in all its domains for spondylolisthesis patients. It showed a factorial structure consistent with the original questionnaire, with 60% of explained variance under four factors. Moderate to high correlation coefficients were found for specifically corresponding domains between SRS-22fv and SF-12v2. Boys had higher scores than do girls, scores worsened with increasing age and body mass index. Analysis of covariance showed statistically significant differences between patients with spondylolisthesis, patients with AIS, and controls when controlling for age, sex, body mass index, pain, function, and self-image scores. In the spondylolisthesis group, scores on all domains and mean total scores were significantly lower in surgical candidates and in patients with high-grade spondylolisthesis. Low to moderate ceiling effects were shown in function (1.1%), self-image (10.7%), and pain (13.6%). CONCLUSION The SRS-22fv can discriminate between healthy and spondylolisthesis subjects. It can be used in spondylolisthesis patients to assess health-related quality of life. LEVEL OF EVIDENCE 4.
