The reunion with my patients: their journey and experience 30 years after their intervention for adolescent idiopathic scoliosis via CD instrumentation

PURPOSE

Our objective was to collect the experience and current attitude of those patients, now adults, operated on for adolescent idiopathic scoliosis (AIS) more than 25 years ago with CD instrumentation (CDI).

METHODS

Prospective qualitative cross-sectional study with interpretive phenomenological analysis approach of AIS patients operated in a single center with CDI between 1985 and 1995. Patients underwent a semi-structured interview with their original surgeon. Seven agreed themes were open for conversation, and several subthemes emerged related to their experience during their journey in life. Filed notes were recorded and transcribed verbatim. We used the method of content, semantic and pragmatic analysis.

RESULTS

We contacted 103 patients, 100 agreed to participate. Mean age was 47.5 ± 3.3, mean follow-up was 30.9 ± 2.7 years. Three fundamental concerns stood out: discomfort with self-image; low back pain with daily activities; and lack of spinal flexibility. 50% were engaged in continuous physical exercise, and only some referred limitations with load-bearing work. Patients commonly described negative memories of the conservative treatment, but positive memories of the surgical process. In general, there was a good adaptation to social life (occupation, social and family relationships). Two-thirds were married, and 65 women had offspring. A frequent concern was the excess of radiographs over the years, and three developed breast cancer.

CONCLUSIONS

Factors such as dissatisfaction with self-image, low back pain, and spine stiffness were relevant to patients throughout their journeys. Despite this, the great majority were satisfied with the treatment received, which allowed them to lead an integrated life in society.

What is the effect of preoperative depression on outcomes after minimally invasive surgery for adult spinal deformity? A prospective cohort analysis

OBJECTIVE

Depression has been implicated with worse immediate postoperative outcomes in adult spinal deformity (ASD) correction, yet the specific impact of depression on those patients undergoing minimally invasive surgery (MIS) requires further clarity. This study aimed to evaluate the role of depression in the recovery of patients with ASD after undergoing MIS.

METHODS

Patients who underwent MIS for ASD with a minimum postoperative follow-up of 1 year were included from a prospectively collected, multicenter registry. Two cohorts of patients were identified that consisted of either those affirming or denying depression on preoperative assessment. The patient-reported outcome measures (PROMs) compared included scores on the Oswestry Disability Index (ODI), numeric rating scale (NRS) for back and leg pain, Scoliosis Research Society Outcomes Questionnaire (SRS-22), SF-36 physical component summary, SF-36 mental component summary (MCS), EQ-5D, and EQ-5D visual analog scale.

RESULTS

Twenty-seven of 147 (18.4%) patients screened positive for preoperative depression. The nondepressed cohort had an average of 4.83 levels fused, and the depressed cohort had 5.56 levels fused per patient (p = 0.267). At 1-year follow-up, 10 patients still reported depression, representing a 63% decrease. Postoperatively, both cohorts demonstrated improvement in their PROMs; however, at 1-year follow-up, those without depression had statistically better outcomes based on the EQ-5D, MCS, and SRS-22 scores (p < 0.05). Patients with depression continued to experience higher NRS leg scores at 1-year follow-up (3.63 vs 2.22, p = 0.018). After controlling for covariates, the authors found that depression significantly impacted only 1-year follow-up MCS scores (β = 8.490, p < 0.05).

CONCLUSIONS

Depressed and nondepressed patients reported similar improvements after MIS surgery, except MCS scores were more likely to improve in nondepressed patients.

Heath-related quality of life and functional outcomes in patients with congenital or juvenile idiopathic scoliosis after an average follow-up of 25 years: a cohort study

BACKGROUND CONTEXT

Congenital and juvenile scoliosis are both early-onset deformities that develop before the age of 10. Children are treated to prevent curve progression and problems in adulthood such as back pain and a decreased quality of life but literature on long-term outcomes remains scarce.

PURPOSE

To evaluate the health-related quality of life (HRQoL) and potential disability of children with congenital scoliosis (CS) or juvenile idiopathic scoliosis (JIS) after a minimum of 20 years follow-up.

STUDY DESIGN

Comparative cohort study.

PATIENT SAMPLE

A consecutive cohort of CS and JIS patients were retrospectively identified from a single-center scoliosis database. Patients born between 1968 and 1981 and treated during skeletal growth were eligible for participation.

OUTCOME MEASURES

HRQoL (SF-36, SRS-22r, ODI).

METHODS

The primary aim was to evaluate the HRQoL of CS and JIS patients using the general SF-36 questionnaire. Both patient cohorts were compared with age-matched national norms. The secondary aim was to analyze the differences between conservatively and surgically treated patients using the scoliosis-specific Scoliosis Research Society-22r questionnaire (SRS-22r) and the Oswestry Disability Index (ODI). T-tests were used for statistical comparison.

RESULTS

In total, 114 patients (67% of the eligible patients) completed the questionnaire, with a mean follow-up of 25.5±5.5 years after their final clinical follow-up. Twenty-nine patients with CS were included with a mean age of 44.4±3.8 years (79.3% female), and 85 patients with JIS with a mean age of 43.7±4.2 years (89.4% female). Of the SF-36 domains, only the vitality score (60.6±18.0 for CS and 58.1±17.6 for JIS cohort) and mental health score (70.0±18.4 for CS and 72.1±18.1 for JIS cohort) were significantly lower compared with the general population (68.6±19.3 for vitality, and 76.8±17.4 for mental health). These decreased scores were larger than the determined minimum clinically important difference threshold of 4.37. Surgically treated JIS patients had a significantly lower score on the SRS-22r pain domain than their nonsurgically treated peers (3.6±0.9 vs 4.1±0.7l p=.019). Surgically treated CS patients had a significantly higher score on the SRS-22r mental health domain than their nonsurgically treated peers (4.3±0.5 vs 3.5±1.0; p=.023). No significant differences were found in the other domains.

CONCLUSIONS

Except for vitality and mental health domains, congenital and juvenile idiopathic scoliosis patients treated during skeletal growth had similar HRQoL on most SF-36 domains in adulthood compared with national norms. Surgical treated JIS patients experienced more pain compared with brace treated patients, while braced CS patients had a significantly lower mental scores compared with surgical treated patients. These long-term outcomes are essential to inform patients and can guide shared decision-making between clinicians and patients.

Adolescent idiopathic scoliosis: interdisciplinary creative art practice and nature connections

Scoliosis is an abnormal lateral curvature of the spine with the large majority of cases classed as idiopathic, meaning there is no known cause. Typically, most cases occur in children and young people affecting approximately three per cent of the adult populace with five out of six cases being female. The BackBone: Interdisciplinary Creative Practices and Body Positive Resilience pilot research study used arts and humanities methods to measure the impact of adolescent idiopathic scoliosis (AIS) on well-being and body perception. The research aimed to contribute to a better understanding of alternative treatments towards improving quality of life in young women diagnosed with AIS. In particular, concentrating on two highlighted priorities from the Scoliosis Priority Setting Partnership: (1) How is quality of life affected by scoliosis and its treatment? How can we measure this in ways that are meaningful to patients? (2) How are the psychological impacts (including on body image) of diagnosis and treatment best managed.Using established medical techniques, art-based workshops, and focus groups with postoperative participants with AIS and their families we gathered both quantitative and qualitative data. The workshops explored the aesthetics of imperfection through material investigations that focus on the body as both an object and how it is experienced using the metaphor of tree images. Drawing parallels between the growth patterns of trees that, for complex and often unknown reasons, have grown unexpectedly we explored questions around ideological notions of perfect growth through art-making in a non-clinical setting. Uniquely, the pilot project sought to draw on insights from four key disciplines (art, medicine, psychology and human geography), thinking across boundaries to evoke different ways of knowing and understanding the complexities of body perception through image-making.

Health-Related Quality of Life of Patients with Postural Kyphosis Compared to Spinal Deformities in Adolescence: A Cross-Sectional Study

AIM

To evaluate the quality of life of patients with postural kyphosis (PK) compared with those adolescent idiopathic scoliosis (AIS) and Scheuermann Kyphosis (SK).

MATERIAL AND METHODS

Health-related quality of life (HRQoL) of adolescents with PK who were admitted to our clinic between January 2020 and June 2022 was compared with that of patients with AIS and SK who were admitted during the same period by using the Scoliosis Research Society-22 (SRS-22) questionnaire. All patients were asked to complete the SRS-22 questionnaire before the radiological evaluation. In the radiological evaluation, the sagittal and coronal deformities of the patients were measured.

RESULTS

In total, 126 patients with PK were compared with age and sex-matched AIS patients and 42 SK patients. The mean SRS-22 function score of the PK group was 4.72 ± 0.3 while it was 4.38 ± 0.6 (p=0.015) in SK patients and it was 4.34 ± 0.6 (p < 0.001) in AIS patients. The mean SRS-22 pain scores of PK patients was 4.18 ± 0.7. The mean pain score was 3.68 ± 0.8 (p=0.033) in the SK group and 3.6 ± 0.8 (p=0.010) in the AIS group. Adolescents with PK perceived less pain than those with AIS or SK. The scores for the other domains of SRS-22 revealed no differences.

CONCLUSION

HRQoL of patients with PK is reduced, similar to that of patients with common structural spine deformities. Recognizing the effects of PK on the HRQoL in adolescents can help physicians to treat these patients.

From PHQ-2 to SRS-22: how a depression screening tool relates to SRS scores in patients with adolescent idiopathic scoliosis

PURPOSE

The aim of our study was to determine the relationship between Patient Health Questionnaire (PHQ) scores-a simple, validated depression screening tool-and Scoliosis Research Society (SRS)-22 questionnaire scores in patients with idiopathic scoliosis (IS).

METHODS

IS patients screened for depression with the PHQ-2 who completed the SRS-22 over a 2-year period were reviewed. If PHQ-2 scores were positive (> 3), the more comprehensive PHQ-9 was administered. Median SRS-22 scores between positive and negative PHQ screens were compared. Nonparametric correlation between PHQ and SRS-22 Mental Health (MH) domain was performed. The ability of the MH domain to discriminate between patients with positive versus negative screens and patients with moderate-severe depression risk versus no-mild risk was evaluated with ROC analysis.

RESULTS

521 patients were included. Patients with + PHQ-2 screens had significantly lower total and individual domain SRS scores, especially within the MH domain (4.0 vs. 3.2). For those with moderate-severe depression risk, total and individual domain scores were also significantly lower (MH domain, 4.0 vs. 3.0, p < 0.05). A weak, but significant correlation was observed between the PHQ and MH domain scores (rho = 0.32, p < 0.001). A cut-off of ≥ 3.6 on the MH domain demonstrated sensitivity of 0.75 and specificity of 0.86 for identifying patients at no-mild risk for depression.

CONCLUSION

Recognizing mental health conditions is critical to successful IS treatment as psychosocial conditions can negatively affect treatment outcomes. IS patients scoring < 3.6 on the SRS-22 MH domain should be considered for depression screening due to an increased risk of moderate-severe depression.

Psychosocial Effect of Brace Treatment in Adolescent Idiopathic Scoliosis: A Study Using EQ-5D

STUDY DESIGN

Retrospective cohort study.

OBJECTIVE

To evaluate psychosocial effect of brace treatment in adolescent idiopathic scoliosis (AIS) using EuroQoL 5-dimension (EQ-5D) depression and anxiety category.

BACKGROUND

AIS is a structural abnormality of the spine often affecting patients during the puberty, a critical period of developing psychosocial problems. Many questionnaires had been adapted to evaluate mental health and health-related quality of life of AIS patients. However, these questionnaires are often time consuming and difficult to obtain. Therefore, a simpler substitute-EQ-5D-was evaluated.

METHODS

This is a single-center retrospective cohort analysis of adult idiopathic scoliosis patients aged between 8 and 19, visiting outpatient's clinic. Beck's depression inventory, EQ-5D and EuroQoL visual assessment scale, and Objectified Body Consciousness Scale for Youth were compared between brace group and non-brace group of AIS patients. Furthermore, difference between male and female were evaluated within brace group.

RESULTS

None of the questionnaire showed significant difference between brace and non-brace group. However, when male and female patients were compared within brace group, female patients were significantly more susceptible to depression and anxiety based on EQ-5D and body consciousness. Furthermore, depression and anxiety according to both BDI and EQ-5D were significantly correlated to health-related quality of life.

CONCLUSION

During brace treatment of female AIS patients, psychosocial status played a significant role in health-related quality of life. EQ-5D is a simple way to monitor the mental health status.

SRS-22r Self-Image After Surgery for Adolescent Idiopathic Scoliosis at 10-year Follow-up

STUDY DESIGN

Retrospective cohort.

OBJECTIVE

To examine SRS-Self Image scores at up to 10 years after surgery for adolescent idiopathic scoliosis (AIS).

SUMMARY OF BACKGROUND DATA

Self-image is complex with implications for surgical and patient-reported outcomes after AIS surgery. Surgically modifiable factors that impact self-image are inconsistently reported in the literature with few longer-term reports. We examined the rate and durability of self-image improvement.

MATERIALS AND METHODS

An AIS registry was queried for patients with up to 10 years of follow-up after AIS surgery. A mixed effects model estimated change in SRS-22 Self Image from baseline to 6 weeks, 1 year, 2 years, 5 years, and 10 years. All enrolled patients contributed data to the mixed effects models. A sub-analysis of patients with 1-year and 10-year follow-up evaluated worsening/static/improved SRS-22 Self Image scores examined stability of scores over that timeline. Baseline demographic data and 1-year deformity magnitude data were compared between groups using parametric and nonparametric tests as appropriate.

RESULTS

Data from 4608 patients contributed data to the longitudinal model; 162 had 1-year and 10-year data. Mean SRS-Self Image improvement at 10-year follow-up was 1.0 (95% CI: 0.9-1.1) point. No significant changes in Self-Image domain scores were estimated from 1-year to 10-year (all P >0.05) postoperative. Forty (25%) patients had SRS-Self Image worsening from 1 year to 10 years, 36 (22%) improved, and 86 (53%) were unchanged. Patients who worsened over 10 years had lower SRS-Self Image at baseline than those unchanged at enrollment (3.3 vs. 3.7, P =0.007). Neither radiographic parameters nor SRS-Mental Health were different at baseline for the enrolled patients.

CONCLUSION

Ten years after surgery, 75% of patients reported similar or better SRS-Self Image scores than one year after surgery. Nearly 25% of patients reported worsening self-image at 10 years. Patients who worsened had lower baseline SRS-Self Image scores, without radiographic or mental health differences at baseline or follow-up.

Adolescent idiopathic scoliosis patients treated with bracing, surgery, or observation showed no difference in behavioral and emotional function over a 2-year period

The purpose of this study was to assess if behavior and emotional function, as measured by the Pearson Behavioral Assessment Survey for Children, Second Edition (BASC-2) in patients and parents, changes with differing treatment protocols in patients with adolescent idiopathic scoliosis (AIS). One previous study showed abnormal BASC-2 scores in a substantial number of patients diagnosed with AIS; however, no study has assessed how these scores change over the course of treatment. AIS patients aged 12 to 21 years completed the BASC-2. The 176-item questionnaire was administered to subjects at enrollment, assessing behavioral and emotional problems across 16 subscales of 5 domains: school problems, internalizing problems, inattention/hyperactivity, emotional symptoms index, and personal adjustment. Parents were given an equivalent assessment survey. Surveys were administered again after 2 years. Subject treatment groups (bracing, surgery, and observation) were established at enrollment. Patients were excluded if they did not complete the BASC-2 at both time points. Forty-six patients met the inclusion criteria, with 13 patients in the surgical, 20 in the bracing, and 13 in the observation treatment groups. At enrollment, 26% (12/46) of subjects with AIS had a clinically significant score in 1 or more subscales, and after 2 years 24% (11/46) of subjects reported a clinically significant score in at least 1 subscale (P = .8). There were no significant differences in scores between enrollment and follow-up in any treatment group. Similar to what was reported in a previous study, only 36% (4/11) of patients had clinically significant scores reported by both patient and parent, conversely 64% (7/11) of parents were unaware of their child's clinically significant behavioral and emotional problems. Common patient-reported subscales for clinically significant and at-risk scores at enrollment included anxiety (24%; 11/46), hyperactivity (24%; 11/46), attention problems (17%; 8/46), and self-esteem (17%; 8/46). At 2-year follow-up, the most commonly reported subscales were anxiety (28%; 13/46), somatization (20%; 9/46), and self-esteem (30%; 14/46). Patients with AIS, whether observed, braced or treated surgically, showed no significant change in behavior and emotional distress over the course of their treatment, or compared with each other at 2-year follow-up.

Greek Adaptation and Validation of the Bad Sobernheim Stress Questionnaire-Brace and the Bad Sobernheim Stress Questionnaire-Deformity

Adolescent idiopathic scoliosis (AIS) is a progressive condition responsible for spinal deformity in all three planes. Spinal deformity and how the rib hump affects the aesthetics, and the functionality of the trunk can be a cause of psychological distress as well. Bracing as a treatment can have a negative impact on QoL, cause pain, affect participation levels in physical activities, and cause isolation and depression. Brace-induced stress may affect the patient's compliance with the treatment which may lead to scoliosis progression. The purpose of this study was to adapt and validate in the Greek language two instruments that can evaluate stress levels induced by bracing treatment and by deformity. The process of cross-cultural adaptation and validation of the Bad Sobernheim Stress Questionnaire-Brace (ΒSSQ-Brace) and the Bad Sobernheim Stress Questionnaire-Deformity (BSSQ-Deformity) followed the International Quality of Life Assessment Project (IQOLA) guidelines. Forty-seven AIS patients with a mean age of 14.4 ± 1.51 years, mean Cobb angle of 30.08 ± 9.25, and mean duration of the bracing treatment at 20.5 ± 12.2 months participated. The mean score for GR-BSSQ Brace was 14.04 ± 6.42, which is interpreted as medium stress, whereas the mean score for GR-BSSQ Deformity was 20.34 ± 3.78, which is interpreted as low stress. GR-BSSQ Brace demonstrated good internal consistency with Cronbach's α = 0.87. GR-BSSQ Deformity demonstrated acceptable internal consistency with Cronbach's α = 0.73. Both GR-BSSQ Brace and GR-BSSQ Deformity exhibited excellent test-retest reliability with ICC values of 0.94 (95% CI 0.89-0.97) and 0.92 (95% CI 0.86-0.95), respectively. BSSQ Brace and BSSQ Deformity questionnaires have been cross-culturally adapted into the Greek language and have been proven to be valid and reliable instruments measuring brace and deformity-induced stress. Both questionnaires can be used for clinical and research purposes in Greek-speaking population.

Is higher compliance to brace therapy associated with poorer quality of life and self-image? A 36-months follow-up study

BACKGROUND

Brace treatment is the most effective tool for avoiding curve progression in moderate adolescent idiopathic scoliosis and high adherence is required to achieve therapeutic success. Despite this, the compliance often is impaired by the concern about the psychological well-being of adolescents.

OBJECTIVE

This 36-month follow-up study investigated if the patients most adherent to brace treatment could report a stronger impairment in the quality of life and body image.

METHODS

64 adolescents with idiopathic scoliosis responded to the Scoliosis Research Society-22 revised Patient Questionnaire at 12, 24, and 36 months after prescription of a TLSO rigid brace. Retrospectively, participants who wore a brace for more than 75% of the prescribed time were assigned to the good-compliance group (GC); the others formed the poor-compliance group (PC).

RESULTS

At 12 months the GC group showed higher scores in treatment satisfaction and at 36 months they did not differ from the PC group in the overall SRS-22r score. Moreover, they achieved a statistically significant improvement in the scoliosis severity, although they showed lower scores in the self-image domain.

CONCLUSION

In our patient's cohort, increased brace adherence does not compromise QoL and provides better treatment outcomes. However, more attention is needed to maintain good self-perception.

Cross-cultural adaptation and validation of the Italian Spine Youth Quality of Life (ISYQOL) questionnaire's Arabic version

Health-related quality of life (HRQOL) assessment is considered among the most relevant outcome measures following conservative and surgical interventions for various spinal conditions. Several questions are available to evaluate HRQOL in these conditions. A more recent Italian Spine Youth Quality of Life (ISYQOL) questionnaire was developed for this purpose and showed high validity in measuring HRQOL.To translate and adapt the ISYQOL questionnaire into Arabic language (ISYQOL-Ar) and evaluate its validity and reliability, and to correlate it with the validated revised Scoliosis Research Society (SRS-22r)'s Arabic questionnaire in a cross-sectional multicenter study.The ISYQOL was translated, back-translated, and reviewed by an expert committee. Reliability assessment for the questionnaire domains was performed using Cronbach's alpha. For construct validation, the Pearson's correlation coefficient was used.A total of 115 patients were enrolled in the study and completed the ISYQOL-Ar and Arabic SRS-22r questionnaires. A total of 72 patients (63%) completed the first set of questionnaires, and 2 weeks later, 63 patients (55%) completed both sets of questionnaires, with 15.8 a mean age, 39.5° mean Cobb angle of 88.9% females. ISYQOL-Ar showed excellent validity, good reliability, and internal consistency for spine health and brace wear, with Cronbach's alpha > 0.6, similar to SRS-22r in the same cohort. The correlation was significant between ISYQOL-Ar and Arabic SRS-22r (Pearson's coefficient = 0.708, P < .001).The ISYQOL-Ar questionnaire is a reliable and valid outcome measure for the assessment of young patients with spinal deformity among the Arabic-speaking population.

Reliability and validity of Chinese version of brace questionnaire for adolescent idiopathic scoliosis: A cross-sectional study

There is an increasing concern about the impact of bracing on the quality of life (QoL) of patients with adolescent idiopathic scoliosis (AIS). However, up to now, few multidimensional questionnaires on this impact are available in China. This study aimed to evaluate the reliability and validity of the Chinese version of Brace Questionnaire (C-BrQ).The BrQ was translated from Greek into Chinese with proper cross-cultural adaptation.An observational, cross-sectional study in Chinese patients with AIS was conducted to measure the temporal stability of C-BrQ using the intraclass correlation coefficient (ICC). The effects of ceiling and floor were evaluated and the reliability was verified by examining the internal consistency. The C-BrQ domains were compared with the domains in Chinese version of Scoliosis Research Society-22 Outcomes Questionnaire (C-SRS-22) using Pearson correlation coefficient to assess the concurrent validity.A total of 208 patients were included in the study. The results of test-retest reliability for each dimension of C-BrQ were desirable. The floor or ceiling effects were not demonstrated in the C-BrQ and C-SRS-22. Satisfactory internal consistency was found in all the C-BrQ domains. Most C-BrQ and C-SRS-22 domains showed satisfactory correlation coefficients, except when vitality and school activity in C-BrQ were compared with self-image, mental health, and management satisfaction in C-SRS -22, respectively.C-BrQ is reliable in evaluating the QoL of AIS patients receiving brace treatment.

Is There an Association Between Psychiatric Disorders and Adolescent Idiopathic Scoliosis? A Large-database Study

BACKGROUND

Children with adolescent idiopathic scoliosis (AIS) have reduced quality of life related to poor self-image, perhaps because of cosmetic concerns. However, there has not been a large-database epidemiologic study on the association between psychiatric disorders and scoliosis.

QUESTIONS/PURPOSES

Using the Korean National Health Insurance database, we asked: (1) How common are psychiatric disorders among children with AIS? (2) After controlling for gender, age, insurance type, and residential district, are psychiatric disorders more common among children with AIS than among age-matched controls?

METHODS

A retrospective analysis was conducted using sample datasets from the Health Insurance Review and Assessment Service from 2012 to 2016, which is a 10% randomly extracted sample of total inpatients and outpatients each year. The mean number of total patients in each dataset was 1,047,603 ± 34,534. The mean number of children with AIS was 7409 ± 158 for each year. The age criteria was 10 to 19 years for the matching. Mood disorders, anxiety disorders, and behavioral disorders were selected as disorders possibly associated with AIS. We identified children with AIS who had any of the disorders above, and we obtained the prevalence of these disorders based on diagnostic codes. As an exploratory analysis, clinically meaningful variables were selected among the available codes in the dataset, and a univariable logistic regression test was performed for each variable. A multivariable logistic regression test with advanced variables was performed to identify the adjusted odds ratios of psychiatric disorders in children with AIS.

RESULTS

The median (range) prevalence of psychiatric disorders in children with AIS from 2012 to 2016 was 7% (6% to 7%). Compared with children who did not have AIS, and after controlling for gender, age, insurance type, and residential district, children with AIS were more likely to have psychiatric disorders in all 5 years. The adjusted ORs of psychiatric disorders in children with AIS compared with children who did not have AIS ranged from 1.47 to 1.74 (2012: OR 1.60 [95% CI 1.46 to 1.75]; p < 0.001; 2013: OR 1.73 [95% CI 1.58 to 1.89]; p < 0.001; 2014: OR 1.74 [95% CI 1.59 to 1.91]; p < 0.001; 2015: OR 1.71 [95% CI 1.56 to 1.88]; p < 0.001; 2016: OR 1.47 [95% CI 1.33 to 1.62]; p < 0.001).

CONCLUSION

Considering the higher prevalence of psychiatric disorders in children with AIS compared with children who did not have AIS, children with AIS and their parents should be counseled about the increased risk of deteriorating mental health of the patients, and surgeons should provide early referral to pediatric psychiatrists. Further studies should investigate the effect of the factors related to AIS, such as curve type, Cobb angle, and treatment modality.

Improvement in SRS-22R Self-Image Correlate Most with Patient Satisfaction after 3-Column Osteotomy

STUDY DESIGN

Longitudinal cohort.

OBJECTIVES

The aim of this study was to examine the relationship between patient satisfaction, patient-reported outcome measures (PROMs) and radiographic parameters in adult spine deformity (ASD) patients undergoing three-column osteotomies (3CO).

SUMMARY OF BACKGROUND DATA

Identifying factors that influence patient satisfaction in ASD is important. Evidence suggests Scoliosis Research Society-22R (SRS-22R) Self-Image domain correlates with patient satisfaction in patients with ASD.

METHODS

This is a retrospective review of ASD patients enrolled in a prospective, multicenter database undergoing a 3CO with complete SRS-22R pre-op and minimum 2-years postop. Spearman correlations were used to evaluate associations between the 2-year SRS Satisfaction score and changes in SRS-22R domain scores, Oswestry Disability Index (ODI), and radiographic parameters.

RESULTS

Of 135 patients eligible for 2-year follow-up, 98 patients (73%) had complete pre- and 2-year postop data. The cohort was mostly female (69%) with mean BMI of 29.7 kg/m2 and age of 61.0 years. Mean levels fused was 12.9 with estimated blood loss of 2695 cc and OR time of 407 minutes; 27% were revision surgeries. There was a statistically significant improvement between pre- and 2-year post-op PROMs and all radiographic parameters except Coronal Vertical Axis. The majority of patients had an SRS Satisfaction score of ≥3.0 (90%) or ≥4.0 (68%), consistent with a moderate ceiling effect. Correlations of patient satisfaction was significant for Pain (0.43, P < 0.001), Activity (0.39, P < 0.001), Mental (0.38, P = 0.001) Self-Image (0.52, P < 0.001). ODI and Short-Form-36 Physical component summary had a moderate correlation as well, with mental component summary being weak. There was no statistically significant correlation between any radiographic or operative parameters and patient satisfaction.

CONCLUSION

There was statistically significant improvement in all PROMs and radiographic parameters, except coronal vertical axis at 2 years in ASD patients undergoing 3CO. Improvement in SRS Self-Image domain has the strongest correlation with patient satisfaction.Level of Evidence: 3.

Long-term Patient Perception Following Surgery for Adolescent Idiopathic Scoliosis if Dissatisfied at 2-year Follow-up

STUDY DESIGN

Longitudinal.

OBJECTIVES

To evaluate whether the rate of patients who report low health-related quality of life (HRQOL) scores at 2 years following surgical correction of adolescent idiopathic scoliosis (AIS) improves by 5 years postoperatively.

SUMMARY OF BACKGROUND DATA

HRQOL scores are dependent upon a number of factors and even in instances of good surgical correction of a spinal deformity, are not guaranteed to be high postoperatively. Understanding how a low HRQOL score varies over the postoperative period can help surgeons more effectively counsel patients and temper expectations.

METHODS

A multicenter database was reviewed for patients with both 2 and 5-year follow-up after spinal fusion and instrumentation for AIS. From a cohort of 916 patients, 52 patients with low HRQOL scores at their 2-year follow-up were identified and reevaluated at 5-year follow-up. A low HRQOL outcome was defined as having SRS-22 domain or total scores less than 2 standard deviations below the mean score. Reoperations were also evaluated to determine if they were associated with HRQOL scores.

RESULTS

Of those patients with low SRS-22 HRQOL scores at 2 years postoperatively, improvements were seen in all SRS-22 domains and total scores at the 5-year time point. The greatest change was seen in the satisfaction category where 41 patients showed improvement. The rate of reoperations during this period did not significantly impact patient-reported outcomes.

CONCLUSIONS

Having a low HRQOL score 2 years after surgery for AIS does not guarantee a low score 5 years after surgery. Promisingly, most patients demonstrate some improvement in all domains for patient-reported SRS-22 scores at 5-year compared to 2-year follow-up. Understanding the longer term postoperative evolution in patient-reported outcomes may help surgeons to effectively manage and counsel patients who are dissatisfied in the short term.Level of Evidence: 3.

Depression Symptoms Are Associated with Poor Functional Status Among Operative Spinal Deformity Patients

STUDY DESIGN

Retrospective review of prospective multicenter database.

OBJECTIVE

The aim of this study was to investigate how preoperative mental status affects preoperative and postoperative disability and health scores in adult spinal deformity (ASD) patients.

SUMMARY OF BACKGROUND DATA

The relationship between health-related quality of life (HRQOL) and depression has previously been documented. However, the influence of depression on clinical outcomes among ASD patients is not well understood.

METHODS

ASD patients with minimum 2-year follow-up were stratified based on preoperative mental health measured by Short Form 36 (SF-36) mental component score (MCS). Patients with MCS in the 25th and 75th percentile of the cohort were designated as having low and high MCS, respectively. After matching by preoperative demographics and deformity, pre- and post-HRQOL were compared between the two groups. Further analysis was performed to identify individualized questions on the SF-36 that could potentially screen for patients with low MCS.

RESULTS

Five hundred thirteen patients were assessed (58.4 years' old, 79% women, mean MCS 45.5). Thresholds for low and high MCS cohorts were 35.0 and 57.3, respectively. After matching by preoperative alignment, low MCS patients had worse Oswestry Disability Index (ODI) (52.3 ± 17.0 vs. 35.7 ± 14.6, P < 0.001) and Scoliosis Research Society-22R scores for all domains (all P < 0.001) compared to high MCS patients. Similar results were maintained at 2-year postop, with low MCS patients having a worse ODI (35.2 ± 20.2 vs. 19.7 ± 18.6, P < 0.001) and MCS (42.4 ± 13.5 vs. 58.6 ± 7.1, P < 0.001). Despite similar preoperative Physical Component Score (PCS), low MCS patients were less likely to reach MCID for PCS (46.1% vs. 70.6%, P < 0.01) and had a lower satisfaction at 2-year follow-up (3.88 ± 1.07 vs. 4.39 ± 0.94, P < 0.001). Questions 5a, 9d, and 9f on the SF-36 were found to be independent predictors of low MCS.

CONCLUSION

ASD patients with low MCS are more likely to experience functional limitations before and after surgery and are less likely to be satisfied postoperatively, even when similar clinical goals are achieved. Incorporating psychological factors may assist in decision making.Level of Evidence: 3.

Quality of life of adolescent idiopathic scoliosis patients under brace treatment: a brief communication of literature review

PURPOSE

To identify the life domains that are most frequently reported to be affected in scoliosis patients undergoing brace treatment.

METHODS

A search within the PubMed database was conducted and a total of 60 publications were selected. We classified the studies based on the methods used to measure patients' quality of life (QoL) and categorized the life domains reported to be affected.

RESULTS

Self-image/body configuration was the most reported affected domain of patients' QoL, identified in 32 papers, whilst mental health/stress was the second most reported affected domain. Mental health was identified in 11 papers, and 11 papers using the BSSQ questionnaire reported medium stress amongst their participants. Vitality was the third most reported affected domain, identified in 12 papers.

CONCLUSIONS

Our review indicates that scoliotic adolescents treated with bracing suffer in their quality of life most from psychological burdens. To improve these patients' life quality, more attention should be focussed on supporting their mental health.

Improvement of Pulmonary Function Measured by Patient-reported Outcomes in Patients With Spinal Muscular Atrophy After Growth-friendly Instrumentation

BACKGROUND

Children with spinal muscular atrophy (SMA) sustain a progressive reduction in pulmonary function (PF) related to both muscular weakness and the concomitant effects of spinal deformity on the thorax. Growth-friendly instrumentation is commonly utilized for younger patients with scoliosis and SMA to halt the progression of spinal curvature, but its effect on PF in these patients has not previously been investigated. Using the change in Early Onset Scoliosis 24-Item Questionnaire (EOSQ-24) PF subdomain scores, the authors will investigate whether PF improves in patients with SMA after a growth-friendly intervention.

METHODS

This was a multicenter retrospective cohort study from 2 international registries of patients with SMA undergoing spinal deformity surgery from 2005 to 2015. Data collected were age, sex, degree of major coronal curve, type of growth-friendly construct, forced vital capacity (FVC), and EOSQ-24 scores at the patient's preoperative, 1-year postoperative, and 2-year postoperative visits. Differences in EOSQ-24 PF scores and FVC between baseline and postoperative assessment were examined by paired tests.

RESULTS

A total of 74 patients were identified (mean age, 7.6±2.3 y, major curve 68.1±22.4 degrees, 51.4% female individuals). The mean EOSQ-24 PF scores improved significantly from 70.6 preoperatively to 83.6 at 1 year (P=0.092) and 86.5 at 2 years postoperatively (P=0.020). The scores in patients with rib-based constructs showed steeper increases at 1-year assessments than those in patients with spine-based constructs. The mean paired FVC value decreased from 63.9% predicted preoperatively, to 57.6% predicted at 1 year postoperatively (P=0.035), and 61.9% predicted preoperatively, to 56.3% predicted at 2 years postoperatively (P=0.178).

CONCLUSIONS

Patients with SMA who received growth-friendly instrumentation did experience improvements in PF as measured by EOSQ-24 assessing the caregivers' perception. Given the uncertain reliability of PFTs in this young population, EOSQ-24 is an important tool for measuring improvements in health-related quality of life.

Reliability and validity of a cross-culturally adapted Hindi version of the SRS-22r questionnaire in Indian patients

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.

Scoliosis-specific exercises: A state of the Art Review

Scoliosis-specific exercises are prescribed and used by many centers either primarily or as an adjunct to other treatment methods for adolescent idiopathic scoliosis of mild to moderate severity. These methods are often used in Europe and are being used in the United States with increasing frequency. There are few publications about these methods in the spine or orthopedic literature. We have performed a review of the relevant literature from the PubMed database to evaluate the evidence for effectiveness of these treatments. We found no studies that provide valid evidence that an exercise method prevents progression of AIS (adolescent idiopathic scoliosis) in patients during their peak growth period. We report our review of selected relevant efforts and provide a description of many of the available treatment programs.

Body Image Disturbance Improvement After Operative Correction of Adolescent Idiopathic Scoliosis

HYPOTHESIS

Body Image Disturbance Questionnaire-Scoliosis version (BIDQ-S) is a sensitive outcomes instrument to evaluate improvements in body image-related psychosocial effects with surgical correction.

DESIGN

Prospective observational study.

INTRODUCTION

The BIDQ-S was previously validated (convergent validity, internal consistency) as a tool to assess body image-related distress and psychosocial impairment in adolescent idiopathic scoliosis (AIS). This study was conducted to evaluate responsiveness to change in the BIDQ-S associated with surgical treatment of AIS two years postoperatively to complete the validation of this questionnaire.

METHODS

Seventy-five consecutive operative AIS patients were enrolled and completed BIDQ-S and Scoliosis Research Society-22 (SRS-22) at preoperative and two-year postoperative visits. Demographic and radiographic data were collected. Preoperative and two-year postoperative BIDQ-S (1 = best, 5 = worst) and SRS-22 scores (1 = worst, 5 = best) were compared using paired t test. Correlations between BIDQ-S and SRS-22 scores were evaluated by linear regression.

RESULTS

Eighty-four percent of the subjects were females, with average age at surgery of 14.4 ± 1.6 years. The mean follow-up was 2.26 years (range 2.0-4.5). The major Cobb was corrected from 50.0° ± 7.2° to 14.2° ± 5.8° (Δ = 71.3% ± 12.1%; p < .0001). There was a significant improvement in BIDQ-S scores after surgery (1.64 ± 0.51 to 1.21 ± 0.38, p < .0001). BIDQ-S improvements were correlated with change in SRS self-image (p = .0055), activity (p = .0057), mental (p = .0018), and overall mean (p = .0007) domains. Preoperative, two-year postoperative, and Δ BIDQ-S score were not associated with major Cobb magnitude, truncal rotation, or Lenke curve type. Patients who reached SRS-22r minimal clinically important difference (MCID) in activity and self-image domains had worse preoperative BIDQ scores than those who did not reach MCID (activity 1.91 vs. 1.54 [1 = best, 5 = worst], p = .0099; self-image 2.08 vs. 1.51, p < .0001). Greater improvement in BIDQ-S was noted in patients who reached MCID in SRS-22 self-image than those who did not (Δ = 0.77 vs. 0.38, p = .0052).

CONCLUSION

BIDQ-S is responsive to surgical correction of AIS. The BIDQ-S is a valuable clinical outcome tool to assess the psychosocial effects of scoliosis in adolescents augmenting existing outcome instruments.

A head-to-head comparison of five-level (EQ-5D-5L-Y) and three-level EQ-5D-Y questionnaires in paediatric patients

PURPOSE

The aim of this study was to assess the psychometric properties of a youth version of the EQ-5D five-level questionnaire (5LY) and its three-level version (3LY) in a sample of Chinese paediatric patients.

METHODS

A consecutive sample of idiopathic scoliosis patients were recruited from a referral outpatient scoliosis center at Hong Kong, China in October 2017 and completed the two versions of EQ-5D-Y. Redistribution properties in each dimension of EQ-5D-Y were analyzed between 5LY and 3LY by logistics regressions. Absolute reduction and relative reduction in ceiling effects from the 3LY to the 5LY were calculated. Test-retest reliability was assessed by examining the Gwet's agreement coefficient (Gwet's AC) for five individual dimension responses over the 2-week period.

RESULTS

A total of 129 idiopathic scoliosis patients completed the two versions of EQ-5D-Y at baseline assessment, among which 70 patients completed the test-retest interview in 2-3 weeks after baseline assessment. For redistribution properties, the proportion of inconsistency was low in all the dimensions, ranging from 0.0% ("Usual activities") to 3.9% ("Pain/discomfort"). Ceiling effects were reduced in four dimensions. "Usual activities" dimension showed significant reduction (absolute and relative reductions: 3.9% and 4.3%; p = 0.025) and the "worried/sad/unhappy" dimension showed the largest significant reduction in ceiling effects (absolute and relative reductions: 7.8% and 9.8%; p = 0.012). The 3LY and 5LY showed very good agreement (> 80%) of individual dimension responses between two assessments, except for the "worried/sad/unhappy" dimension in 3LY.

CONCLUSION

Through this head-to-head comparison, the 5LY had significant improvements in ceiling effects in two dimensions when compared to 3LY but other measurement properties of 3LY and 5LY performed similar in the idiopathic scoliosis patient group.

The Effect of an Innovative Biofeedback SKOL-AS® Treatment on the Body Posture and Trunk Rotation in Children with Idiopathic Scoliosis—Preliminary Study

Background and Objectives: The deformity in idiopathic scoliosis (IS) is three dimensional and effective correction involves all three planes. Recently, the biofeedback method has been implemented in the treatment of scoliosis. The aim of this study was to evaluate the effectiveness of an innovative biofeedback SKOL-AS^® postural training among children with scoliosis. Materials and Methods: The target population for this study was 28 patients (25 girls and 3 boys) aged between 5 and 16 years old diagnosed and treated with progressing low-grade scoliosis. The postural diagnosis consisted of anthropometric measurements, posterior–anterior X-ray imaging, SpinalMeter^® postural assessment and the angle of trunk rotation (ATR) assessment. The SKOL-AS^® treatment comprised of 24 sessions conducted in lying and sitting positions, two times a week. Results: It has been shown that the postural training resulted in the decrease in the ATR value (pre- vs. post-exercise in younger: 5.55 vs. 3.0 and older patients: 5.2 vs. 3.0). The increase in height of the subjects seemed to confirm a positive effect of SKOL-AS^® elongation treatment. In the posterior view, a statistically significant decrease in shoulder asymmetry in the sitting position in younger children has been observed. In the anterior view, the changes in the head position (based on mouth and eye symmetry) have been observed. The statistically significant increase in acromion–heel, acromion–iliac crest and posterior superior iliac spine (PSIS)–heel length values has been shown in younger children on the left side of the body. After treatment, older subjects had higher acromion–iliac crest and PSIS–heel values on the left side of the body. On the right side only PSIS–heel length was higher. In a sitting position, only a small increase in acromion–iliac crest length value has been observed. Conclusions: The SKOL-AS^® biofeedback method could teach good postural habits and teach patients the auto-correction of the spine.

Patients With Idiopathic Scoliosis Run an Increased Risk of Schizophrenia

STUDY DESIGN

Retrospective cohort study.

OBJECTIVES

To investigate a possible linkage between idiopathic scoliosis (IS) and schizophrenia in an adolescent population.

SUMMARY OF BACKGROUND DATA

There is an interesting link between schizophrenia and idiopathic scoliosis: schizophrenia is a disturbance of mental equilibrium, and scoliosis of physical equilibrium, both are multifactorial, genetically determined, start at a young age, and brain development is thought to play a role. Furthermore, both may be presenting symptoms of the genetic disorder 22q11 deletion syndrome. This study poses the question whether these two poorly understood disorders are related.

METHODS

A retrospective cohort study was conducted and consisted of 3,702 Swedish adolescents, collected from the National Patient Register, that underwent inpatient care for IS during 1997-2015. These were matched by age, sex, and date of diagnosis to 370,200 controls, collected from Swedish population data, and then followed up in the National Patient Register to identify in- and outpatient care for schizophrenia diagnosis. Follow-up time was calculated from first IS diagnosis date until date of schizophrenia diagnosis or end of follow-up. Cox proportional regression analysis was performed to estimate hazard ratios (HRs) with 95% confidence intervals (CIs) for being diagnosed with schizophrenia.

RESULTS

Over a median follow-up time of 9.5 years, 0.7% of patients with IS developed schizophrenia versus 0.5% of controls (p = .04). The risk of schizophrenia was significantly higher in patients with IS (HR, 1.52; 95% CI, 1.03-2.23). Using only hospitalized schizophrenia as event, the prevalence for schizophrenia was 0.5% versus 0.3% (p ≤.01; HR, 1.83; 95% CI, 1.17-2.84).

CONCLUSION

This study suggests that patients with IS have increased risk of schizophrenia. Dissatisfaction with one's physical appearance might lead to psychological distress and provoke mental illness in predisposed persons. Alternatively, these two disorders may share a common genetic background.

Psychological Effects of the SRS-22 on Girls With Adolescent Idiopathic Scoliosis

STUDY DESIGN

Prospective, randomized control study.

OBJECTIVES

To determine whether the SRS-22r (SRS-22) has a negative effect on the body image of females with adolescent idiopathic scoliosis (AIS) using the Body Appreciation Scale (BAS).

SUMMARY

The SRS-22 is a validated questionnaire designed by the Scoliosis Research Society (SRS) to assess outcomes of scoliosis patients. Parents and nursing staff have expressed concern that the questionnaire may incite body image concerns when administered to teenagers with AIS.

METHODS

Female AIS patients were prospectively enrolled and randomly assigned to the study or control group. Patients were being observed, braced, or planning operative intervention. Patients in the study group were administered the SRS-22, followed by the BAS. Patients in the control group were administered only the BAS. The BAS is scored from 13 to 65, with higher scores indicating a more positive body image.

RESULTS

45 females were enrolled and assigned to study group (n = 24, SRS-22+BAS) or control group (n = 21, BAS only). There were no differences between the groups in age (p = .55) or Cobb angle (p = .21). There were no differences in overall BAS scores between study (mean = 55.9, range 31-65) and control group participants (mean = 54.2, range 42-64, p = .56). SRS-22 questions and BAS scores had multiple correlations. A higher BAS score is associated with the following SRS-22 questions: being a happy person in the last 6 months, feeling calm and peaceful during the past 6 months, and feeling attractive with one's current back condition. A lower BAS score is associated with the following SRS-22 questions: being down in the dumps, feeling downhearted and blue, and feeling that one's back condition affects personal relationships.

CONCLUSION

Similar BAS scores were observed between the study and control group. Despite concerns regarding the potential negative impact of the SRS-22, taking the questionnaire was not observed to negatively affect patients' body image.

Health-related quality of life in children and adolescent with different types of scoliosis: A cross-sectional study

BACKGROUND

The health-related quality of life (HRQoL) was affected in children and adolescents with scoliosis. However, there was lack of study to compare the HRQoL among patients with different types of scoliosis. We aimed to investigate whether the HRQoL differs among patients with idiopathic, congenital, neuromuscular, and syndromic scoliosis.

METHODS

Children and adolescents with scoliosis were recruited from a single tertiary hospital. The HRQoL, as assessed by the child health questionnaire 50-item parent form, was compared with a reference health sample group using the effect size (ES). Intergroup differences related to scoliosis subtype and severity were explored.

RESULTS

A total of 67 participants with scoliosis (24 idiopathic, 15 congenital, 15 neuromuscular, and 13 syndromic) were analyzed. The HRQoL in patients with neuromuscular scoliosis was affected the most, in both physical (ES range: 0.97-2.4) and psychosocial domains (ES range: 0.92-2.58). To a lesser extent, the physical (ES range: 0.99-1.13) and psychosocial (ES range: 0.8-1.18) domains were also affected in patients with syndromic scoliosis. The domains of family activities (ES = 1.1), role/social-emotional/behavioral (ES = 0.99), general health perception (ES = 0.94), and self-esteem (ES = 0.87) were affected in patients with idiopathic scoliosis. In contrast, only the general health perception domain (ES = 1.27) was affected in patients with congenital scoliosis. Scoliosis severity correlated with scores in the physical domains and some psychosocial domains, while treatment type correlated with scores in the physical domains only. Scoliosis subtype and severity both affected the physical and psychosocial domains, with a stronger impact for subtype.

CONCLUSION

Differences in the HRQoL exist among scoliosis subtypes, with neuromuscular scoliosis being most affected. Although the scoliosis subtype and severity both affect the HRQoL, the subtype is more influential than severity.

Measures of Health-Related Quality of Life Outcomes in Pediatric Neurosurgery: Literature Review

BACKGROUND

Improving value in healthcare means optimizing outcomes and minimizing costs. The emerging pay-for-performance era requires understanding of the effect of healthcare services on health-related quality of life (HRQoL). Pediatric and surgical subspecialties have yet to fully integrate HRQoL measures into practice. The present study reviewed and characterized the HRQoL outcome measures across various pediatric neurosurgical diagnoses.

METHODS

A literature review was performed by searching PubMed and Google Scholar with search terms such as "health-related quality of life" and "pediatric neurosurgery" and then including the specific pathologies for which a HRQoL instrument was found (e.g., "health-related quality of life" plus "epilepsy"). Each measurement was evaluated by content and purpose, relative strengths and weaknesses, and validity.

RESULTS

We reviewed 68 reports. Epilepsy, brain tumor, cerebral palsy, spina bifida, hydrocephalus, and scoliosis were diagnoses found in reported studies that had used disease-specific HRQoL instruments. Information using general HRQoL instruments was also reported. Internal, test-retest, and/or interrater reliability varied across the instruments, as did face, content, concurrent, and/or construct validity. Few instruments were tested enough for robust reliability and validity. Significant variability was found in the usage of these instruments in clinical studies within pediatric neurosurgery.

CONCLUSIONS

The HRQoL instruments used in pediatric neurosurgery are currently without standardized guidelines and thus exhibit high variability in use. Clinicians should support the development and application of these methods to optimize these instruments, promote standardization of research, improve performance measures to reflect clinically modifiable and meaningful outcomes, and, ultimately, lead the national discussion in healthcare quality and patient-centered care.

Long-term effects of conservative treatment of Milwaukee brace on body image and mental health of patients with idiopathic scoliosis

We aimed to provide a complex assessment of adult females with adolescent idiopathic scoliosis (AIS) after a minimum of 23 years after completed Milwaukee brace treatment. In the present study, a comparison between healthy female and AIS patients’ perception of trunk disfigurement, self-image, mental health, pain level and everyday activity was made. Thirty AIS patients with a mean of 27.77 yrs (SD 3.30) after the treatment were included in the study. The control group consisted of 42 females, matching the age profile of the patient group. Study participants from both groups were examined using the same protocol, except for the radiological evaluation. Patients and healthy controls completed the Polish versions of the Scoliosis Research Society (SRS-22) and Spinal Appearance Questionnaire (SAQ). Patients additionally filled the Bad Sobberheim Stress Questionnaire-Deformity (BSSQ-Deformity) and Bad Sobberheim Stress Questionnaire-Brace (BSSQ-Brace). The study group’s SAQ results differ significantly in regard to the total score and all individual domains, indicating better functioning among healthy controls. Except for the General domain (p = 0.002), among the remaining subscales the study group’s results differed significantly at p<0.001. Considering SRS-22 results, it was revealed that the patient group scored higher, signaling better functioning with reference to pain level (p = 0.016), function/activity (p<0.001) and the total score (p<0.001). The findings add to the complexity of long-term effect evaluations of AIS, particularly amongst females treated with a Milwaukee brace. Long-term results were not conclusive in terms of nonverbal assessment of body image and emotional tension regarding the experiences of brace-wearing. Future patients can be reassured that scoliosis treated conservatively does not negatively affect everyday activity, pain level, childbearing and mental health. Subjects who declared to have psychological problems due to scoliosis had a bigger curve size after treatment and in this study than the other AIS patients.

Health-Related Quality of Life Scores Underestimate the Impact of Major Complications in Lumbar Degenerative Scoliosis Surgery

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.

Validation of the Korean version of the Spinal Appearance Questionnaire

OBJECTIVE

To evaluate the reliability and validity of an adapted Korean version of the Spinal Appearance Questionnaire (SAQ).

METHODS

Translation/retranslation of the English version of the SAQ was conducted, and all steps of the cross-cultural adaptation process were performed. The Korean version of the SAQ (K-SAQ) and the previously validated appearance domain of the Korean version of the Scoliosis Research Society-22 Outcomes questionnaire (K-SRS-22) were mailed to 160 patients with adolescent idiopathic scoliosis (AIS). Reliability assessments were conducted using kappa statistics to assess item agreements, and intraclass correlation coefficients (ICC) and Cronbach's α values were calculated. Convergent validity was evaluated by comparing K-SAQ and K-SRS-22 appearance domain scores and discriminant validity by analyzing relationships between K-SAQ scores and patient characteristics.

RESULTS

All items of the K-SAQ had kappa values of agreement of > 0.6. The K-SAQ showed excellent test/re-test reliability with an intraclass correlation coefficient of 0.922. Internal consistency of the K-SAQ was found to be very good (α= 0.883). Convergent validity testing demonstrated a moderate correlation between the K-SAQ and K-SRS-22 (r=-451). The correlation between the K-SAQ and major curve magnitude was significant (r= 0.812). Discriminant validity was confirmed by significant differences in K-SAQ scores and individual K-SAQ domain scores among patients requiring observation, bracing, or surgery.

CONCLUSIONS

The adapted Korean version of the SAQ showed satisfactory reliability and validity, and thus, is considered suitable for the evaluation of spinal deformity appearance in Korean speaking patients with adolescent idiopathic scoliosis.

Social Media and Pediatric Scoliosis: An Analysis of Patient and Surgeon Use

INTRODUCTION

The purpose of this observational study was to investigate and analyze the social media presence of both patients and surgeons in relation to pediatric scoliosis. First, patient Instagram (Instagram, Inc., San Francisco, California) posts were evaluated for 1) media format; 2) timing in relation to surgery; 3) tone; 4) perspective; 5) content; and 6) subject reference. To analyze reciprocal engagement, the presence and activity of pediatric scoliosis surgeons at five major academic centers were subsequently analyzed on Instagram, Twitter (Twitter Inc., San Francisco, California), and LinkedIn (LinkedIn Corporation, Sunnyvale, California).

MATERIALS AND METHODS

A search of public Instagram profiles was performed over a one-year period from February 2016 to February 2017. Posts related to pediatric scoliosis were selected for analysis using a hashtag search with 30 related terms. A total of 982 posts were retrieved, with 669 posts meeting the inclusion criteria. Each post was then evaluated for timing, tone, perspective, and content using a categorical scoring system. An additional analysis was performed using academic orthopaedic hospitals' websites, in which the names of scoliosis surgeons were found and searched for on Instagram, Twitter, and LinkedIn. Their profiles were analyzed for level and length of activity, number of followers or connections, and references to clinical practice.

RESULTS

A total of 669 posts related to scoliosis were analyzed, the majority of which were temporally related to non-operative (74.7%) or post-operative (21.8%) settings. Patients (33.3%), friends and family (34.4%), and professional organizations (23.8%) were the most active contributors. The vast majority of posts were positive in nature (88.9 %) and highlighted the patient experience (79.2%), specifically related to bracing (33.1%), activities of daily living (31.7%), and surgical site or x-rays (25.5%). Of the social media sites analyzed, surgeons were found to have the highest presence on LinkedIn (55% have accounts with a mean of 175 connections) compared to Instagram (8%, 57 followers) and Twitter (33%, 61 followers). Surgeons were also noted to have more information regarding their practice, training, and clinical skills on LinkedIn.

CONCLUSIONS

An analysis of Instagram posts related to scoliosis showed that the majority were shared by patients in the non-operative period and overwhelmingly had a positive tone. The content of the posts focused mainly on brace wear, activities of daily living, and post-operative appearance or x-rays. This information provides further insight into what patients deem important regarding pediatric scoliosis care. Analysis of the social media presence of scoliosis surgeons showed that they have an underwhelming presence on Instagram and Twitter, but are more active on LinkedIn, a site geared more toward professional development and networking than other social media options.

Scoliosis brace design: influence of visual aesthetics on user acceptance and compliance

Adolescent idiopathic scoliosis is a common condition found in adolescents. A rigid brace is often prescribed as the treatment for this spinal deformity, which negatively affects user compliance due to the discomfort caused by the brace, and the psychological distress resulting from its appearance. However, the latter, which is the impact of visual aesthetics, has not been thoroughly studied for scoliosis braces. Therefore, a qualitative study with in-depth interviews has been carried out with 10 participants who have a Cobb angle of 20°-30° to determine the impact of visual aesthetics on user acceptance and compliance towards the brace. It is found that co-designing with patients on the aesthetic aspects of the surface design of the brace increases the level of user compliance and induces positive user perception. Therefore, aesthetic preferences need to be taken into consideration in the design process of braces. Practitioner Summary: The impact of visual aesthetics on user acceptance and compliance towards a rigid brace for scoliosis is investigated. The findings indicate that an aesthetically pleasing brace and the involvement of patients in the design process of the brace are important for increasing user compliance and addressing psychological issues during treatment.

Quality of life in adolescent patients with idiopathic scoliosis after brace treatment: A meta-analysis

BACKGROUND

Whether brace-treated adolescents with idiopathic scoliosis (AIS) have improved quality of life (QoL) is still unknown. Thus, we conducted a meta-analysis to compare the QoL of brace-treated AIS patients with untreated AIS patients. The pain, self-image/appearance, mental health, function/activity, satisfaction with management, total score without satisfaction, and total score of patients were used to measure the QoL after the intervention.

METHODS

Multiple electronic databases including PubMed, Web of Science, and Embase were searched for all years up to June 30, 2016. Articles in English that used the Scoliosis Research Society-22 (SRS-22) or a modified version of the SRS-22 questionnaire to evaluate the QoL differences between brace-treated AIS patients and untreated AIS patients were included in the meta-analysis. The Newcastle-Ottawa Scale was used in the quality of literature evaluation. The pooled standardized mean difference (SMD) with its corresponding 95% confidence interval (CI) for each parameter was computed. Egger test and Begg test were used to test for publication bias.

RESULTS

The SRS-22 or a modified SRS-22 questionnaire was used to evaluate the QoL after surgery. There was no significant difference in pain (SMD = 0.123, 95% CI: -0.101 to 0.347, P = .282), self-image/appearance (SMD = 0.108, 95% CI: -0.116 to 0.332, P = .334), mental health (SMD = 0.031, 95% CI: -0.130 to 0.201, P = .365), function/activity (SMD = 0.202, 95% CI: -0.022 to 0.425, P = .077), and total score without satisfaction (SMD = 0.123, 95% CI: -0.232 to 0.478, P = .497) between the untreated (observation) and brace-treated AIS patients, whereas a significant difference was observed in satisfaction with management (SMD = 0.393, 95% CI: 0.127-0.659, P = .004) and total score (SMD = 0.312, 95% CI: 0.054-0.571, P = .018) between the 2 groups.

CONCLUSION

Our meta-analysis indicated that brace-treated AIS patients had a higher QoL. However, further analysis could not be performed because of insufficient data, such that we were unable to make subgroup analysis of QoL for different types of AIS and the therapeutic methods chosen by brace-treated AIS patients.

Mapping the SRS-22r questionnaire onto the EQ-5D-5L utility score in patients with adolescent idiopathic scoliosis

This is a prospective study to establish prediction models that map the refined Scoliosis Research Society 22-item (SRS-22r) onto EuroQoL-5 dimension 5-level (EQ-5D-5L) utility scores in adolescent idiopathic scoliosis (AIS) patients. Comparison of treatment outcomes in AIS can be determined by cost-utility analysis. However, the mainstay spine-specific health-related quality of life outcome measure, the SRS-22r questionnaire does not provide utility assessment. In this study, AIS patients were prospectively recruited to complete both the EQ-5D-5L and SRS-22r questionnaires by trained interviewers. Ordinary least squares regression was undertaken to develop mapping models, which the validity and robustness were assessed by using the 10-fold cross-validation procedure. EQ-5D-5L utility scores were regressed on demographics, Cobb angle, curve types, treatment modalities, and five domains of the SRS-22r questionnaire. Three models were developed using stepwise selection method. EQ-5D-5L scores were regressed on 1) main effects of SRS-22r subscale scores, 2) as per 1 plus squared and interaction terms, and 3) as per 2 plus demographic and clinical characteristics. Model goodness-of-fit was assessed using R-square, adjusted R-square, and information criteria; whereas the predictive performance was evaluated using root mean square error (RMSE), mean absolute error (MAE), and the proportion of absolute error within the threshold of 0.05 and 0.10. A total of 227 AIS patients with mean age of 15.6 years were recruited. The EQ-5D-5L scores were predicted by four domains of SRS-22r (main effects of ‘Function’, ‘Pain’, ‘Appearance’ and ‘Mental Health’, and squared term of ‘Function’ and ‘Pain’), and Cobb angle in Model 3 with the best goodness-of-fit (R-square/adjusted R-square: 62.1%/60.9%). Three models demonstrated an acceptance predictive performance in error analysis applying 10-fold cross-validation to three models where RMSE and MAE were between 0.063–0.065 and between 0.039–0.044, respectively. Model 3 was therefore recommended out of three mapping models established in this paper. To our knowledge, this is the first study to map a spine-specific health-related quality of life measure onto EQ-5D-5L for AIS patients. With the consideration and incorporation of demographic and clinical characteristics, over 60% variance explained by mapping model 3 enabled the satisfactory prediction of EQ-5D-5L utility scores from existing SRS-22r data for health economic appraisal of different treatment options.

The influence of body image on surgical decisions in adolescent idiopathic scoliosis patients

OBJECTIVES:

The objective of this study was to evaluate whether the severity of deformities in patients with adolescent idiopathic scoliosis contributes to patients' decision regarding whether to undergo an operation.

METHODS:

We evaluated body image factors in adolescent idiopathic scoliosis patients. We evaluated the magnitude of the main scoliotic curve, gibbosity (magnitude and location), shoulder height asymmetry and patient's age. We analyzed the correlation of these data with the number of years the patient was willing to trade for surgery, as measured by the time-trade-off method.

RESULTS:

A total of 52 patients were studied. We did not find a correlation between any of the parameters that were studied and the number of years that the patient would trade for the surgery.

CONCLUSIONS:

The magnitude of body deformities in patients with adolescent idiopathic scoliosis does not interfere with the decision to undertake surgical treatment.

Correlation between the degree of correction of neuromuscular scoliosis and patient quality of life

OBJECTIVE:

There are few data on patient satisfaction with surgery for the correction of neuromuscular scoliosis or on the correlation between patient satisfaction and the degree of curve correction achieved by surgery. Our aim was to determine the correlations between both patient satisfaction and perception of quality of life and the degree of curve correction.

METHODS:

We interviewed 18 patients and administered a questionnaire that collected social and economic data and information about functional ability, comorbidities and satisfaction. Statistical analysis was performed using chi-square tests, Pearson correlation and paired t-tests.

RESULTS:

The mean correction achieved was 42.8%, i.e., 34.17 degrees. Early and late complication rates were low (11.1% each). Almost all of the patients (94.4%) were satisfied with the surgery, and expectations were met for 61.1% of them. Quality of life and aesthetics were improved in 83.4% and 94.4% of cases, respectively. No correlation was found between satisfaction and degree of correction.

CONCLUSION:

Our surgical results are similar to those of other studies with respect to the degree of correction and patient satisfaction. The disparity between satisfaction and fulfillment of expectations may be due to unrealistic initial expectations or misunderstanding of the objective of surgery. Our findings corroborate the hypothesis that satisfaction is multifactorial and not restricted to a quantitative goal. The satisfaction of patients who undergo operation for neuromuscular scoliosis does not depend directly on the degree of deformity correction. The relationship between satisfaction and the success of the correction procedure is complex and multifactorial.

Idiopathic Scoliosis from Psychopathological and Mind-Body Medicine Perspectives

Idiopathic scoliosis, defined as a three-dimensional spine and trunk deformity, which appears in otherwise healthy subjects, exhibits complex relations with various forms of personal well-being and psychopathology. Most research studies have documented a higher proportion of psychological disturbances (e.g., self-criticism, negative body image, low self-esteem) and mental disorders (e.g., anxiety and depressive disorders, personality disorders) among idiopathc scoliosis patients compared to healthy controls. In addition, there are some reports, although more systematic research is warranted, on the role of mental health and personality traits in relation to the adherence to conservative treatment. Given the increasing role of surgical treatment in the management of scoliosis, as well as several reports on negative psychological outcomes of such interventions, there is a growing need for ongoing screening and mental health care in this population. It seems this also holds true for non-operative treatments, particularly bracing therapy. One should keep in mind that these scoliosis-psychopathology relations are deduced from a limited number of empirical studies, usually conducted on small sample sizes, suggesting the need for further large-scale investigations, preferrably those with longitudinal research designs. Understanding the complex interplay between personality/psychopathology and spinal deformities within the framework of personalized mind-body medicine, should help clinicians tailor more individualized and specific treatments and predict therapeutic outcomes in this clinical population.

German validation of the BIDQ-S questionnaire on body image disturbance in idiopathic scoliosis

PURPOSE

The Body Image Disturbance Questionnaire-Scoliosis (BIDQ-S) is a seven-item questionnaire inquiring into patients' worries about back shape and associated problems at school, at work, with friends or family, and whether the patients are avoiding certain activities. The aim of this study was to translate the BIDQ-S into German (G-BIDQ-S), test its reliability, and establish its convergent, divergent, concurrent, and discriminant validity.

METHODS

In a prospective cohort study, 259 patients with idiopathic scoliosis (mean age 30.2; 221 female; mean Cobb angle 43.8°) completed the G-BIDQ-S; Scoliosis Research Society 22-r (SRS 22-r); Patient Health Questionnaire (PHQ-9); Positive and Negative Affect Schedule (PANAS); Questionnaire on Body Dysmorphic Symptoms (FKS); and WHO-5 Well-Being Index. Healthy control individuals matched by age, sex and BMI (n = 149; mean age 36.1; 133 female; BMI = 23.0) answered the same questions to establish discriminant validity. Discriminant statistics, and Pearson and Spearman correlations were calculated.

RESULTS

The G-BIDQ-S proved to be one-factorial, internally consistent (Cronbach alpha = 0.87), and stable over time (total score 2.22 vs. 2.21 during retest; retest reliability r = 0.79, P < 0.001). It correlated significantly with the mean SRS 22-r (r = -0.72, P < 0.001) and with Cobb angles (r = 0.30, P < 0.001)-convergent validity; much less with body mass index (r = 0.19, P < 0.001)-divergent validity; and with the PANAS (r = 0.55, P < 0.001), PHQ-9 (r = 0.53, P < 0.001), FKS (r = 0.67, P < 0.001), and WHO-5 (r = -0.54, P < 0.001)-concurrent validity. The G-BIDQ-S also showed discriminant validity, with a strong difference between the scoliosis group (total score 2.19) and the control group (total score 1.13; P < 0.001).

CONCLUSIONS

The G-BIDQ-S showed good internal consistency, reliability, and convergent, divergent, concurrent, and discriminant validity. This questionnaire is the first one inquiring into patients' body image disturbances that has been validated and is available in German.

Patients' experience of adolescent idiopathic scoliosis surgery: a phenomenological analysis

Background Adolescent idiopathic scoliosis is a three-dimensional curvature of the spine of unknown cause that occurs in often otherwise fit young people. A complex surgical procedure is required for the most severe curves. Quantitative literature suggests scoliosis surgery improves patients' lives, while qualitative literature focuses on patients' concerns rather than their experience. Aims To explore how adolescents interpret their perioperative experience. Method Six participants, aged 15-18, were interviewed and transcripts were analysed. Findings Four themes were identified: shock, fears and worries; parental interaction; coping; and motivation and positivity. Conclusion Participants were reluctant to share concerns, however those they shared related more to fear of the unknown and lack of control than specific issues such as pain. Participants depended on their parents, especially their mothers, during the perioperative period, and they recognised their parents' stress. Participants coped well, were motivated and had a positive outlook.

Comparison of Functional Outcome and Quality of Life in Patients With Idiopathic Scoliosis Treated by Spinal Fusion

Longer spinal fusions have been shown to result in improved deformity correction; however, loss of normal flexibility in the fusion area should not be ignored. Current consensus was to achieve a shorter fusion in primary surgery, with the goal of preserving as much of the distal motion segment as possible. However, the correlation between the length of fusion and functional outcome remains controversial. To the best of our knowledge, a previous study has demonstrated the function outcomes and the differences in HRQoL with specific fusion levels.In this cross-sectional study, 172 patients (mean age, 17.8 y) with idiopathic scoliosis treated by spinal fusion (mean time since surgery, 29.7 mo) were included to measure lumbar spine mobility and quality of life using validated outcome instruments in the study population. Patients were assigned to 5 groups according to the lower instrumented vertebra (LIV) level: group A (fusion above L2) 26 patients; group B (fusion to L2) 21 patients; group C (fusion to L3) 46 patients; group D (fusion to L4) 53 patients; and group E (fusion to L5) 26 patients. At each follow-up, patients were asked to complete the Scoliosis Research Society 22 (SRS-22) Questionnaire. Lumbar mobility was assessed using a dual digital inclinometer.Average spinal range of motion (ROM) was 41.4 degrees (SD, 20.7), forward flexion was 29.2 degrees (SD, 15.0), and backward extension was 12.2 degrees (SD, 9.5). The total spinal range of motion and forward flexion dropped noticeably as the LIV got more distal. Statistically significant between-group differences (1-way ANOVA) were found for ROM (P < 0.001), forward flexion (P < 0.001), or backward extension (P < 0.001). The motion segments preserved significantly correlated with ROM (r = 0.76, P < 0.001), ROMF (r = 0.76, P < 0.001), and ROME (r = 0.39, P < 0.001). However, no significant between-group differences was found for each domain of SRS-22 questionnaire.The motion segments preserved strongly correlated with lumbar mobility. Less fusion levels can preserve better lumbar flexibility by keeping more motion segments.

Chinese Adaptation of the Bad Sobernheim Stress Questionnaire for Patients With Adolescent Idiopathic Scoliosis Under Brace Treatment

Bad Sobernheim Stress Questionnaire (BSSQ)-Deformity and BSSQ-Brace are the most widely used instruments for evaluating stress levels in adolescent idiopathic scoliosis (AIS) patients under brace treatment, and good reliability and validity have been demonstrated across different cultures. Great stress has been found among many adolescents, becoming a major concern for professionals. However, no previous research has addressed the cultural adaptations and psychometric testing of BSSQ-Deformity and BSSQ-Brace in China or the stress levels in AIS patients. The purposes of our study were to evaluate the cross-cultural adaptation and validation of the BSSQ-Deformity and BSSQ-Brace and to investigate stress levels in Chinese (AIS) patients under brace treatment.The original (German) versions of BSSQ-Deformity and BSSQ-Brace were cross-culturally translated according to international guidelines. Psychometric properties such as reliability and construct validity were tested. Eighty-six AIS patients were included in our study, and 50 patients paid a second visit 3 to 7 days later to test reproducibility. Cronbach α and the intraclass coefficient were determined to assess internal consistency and reproducibility. Scoliosis Research Society patient questionnaire-22 (SRS-22) was applied to evaluate construct validity.The mean BSSQ-Deformity and BSSQ-Brace scores were 15.3 and 13.4 points, respectively. Severe stress was observed in 12% of patients due to brace treatment. Item analysis demonstrated that each item was scored under a normal distribution with no redundancy. Psychometric analysis revealed excellent internal consistency (Cronbach α = 0.85 and 0.80, respectively) and reproducibility (intraclass correlation coefficient = 0.85 and 0.90, respectively) for BSSQ-Deformity and BSSQ-Brace. The correlation coefficients of BSSQ-Deformity, BSSQ-Brace and SRS-22 were 0.48 and 0.63, respectively.In conclusion, BSSQ-Deformity and BSSQ-Brace have been successfully adapted to a Chinese background and psychometrically validated with excellent reliability and construct validity. Brace wearing is considered the main cause of stress in AIS patients under brace treatment.

Scoliosis Research Society (SRS) Criteria and Society of Scoliosis Orthopaedic and Rehabilitation Treatment (SOSORT) 2008 Guidelines in Non-Operative Treatment of Idiopathic Scoliosis

According to the Scoliosis Research Society (SRS), idiopathic scoliosis (IS) is a curvature of more than 10° Cobb angle, affecting 2-3% of pediatric population. Idiopathic scoliosis accounts for 80% of all scoliosis cases. Non-operative principles in the therapy of idiopathic scoliosis, including Scoliosis Research Society (SRS) criteria and guidelines proposed by the experts of the Society on Scoliosis Orthopedic and Rehabilitation Treatment (SOSORTS) were presented. The possibility to carry out quality of life assessments in a conservative procedure was also demonstrated. Based on the natural history of idiopathic scoliosis, SRS criteria, SOSORT 2008 experts' opinion and the knowledge of the possibilities of psychological assessment of conservative IS treatment, rules were proposed regarding nonsurgical IS therapy procedures, with special consideration being paid to the proper treatment start time (age, Risser test, biological maturity, Cobb angle), possibility of curvature progression, the importance of physiotherapy and psychological assessment. The knowledge of SRS criteria and SOSORT guidelines regarding the conservative treatment of IS are essential for proper treatment (the right time to start treatment), and supports establishment of interdisciplinary treatment teams, consisting of a physician, a physiotherapist, an orthopedic technician and a psychologist.

Raising awareness of scoliosis among children's nurses

Scoliosis affects up to 3% of adolescents, some babies and young children, and many children with existing neuromuscular and syndromic conditions. It is the most common spinal deformity. Not all children with scoliosis require active intervention, but for more significant, progressive curves, bracing and/or surgery may be required. Bracing studies have historically been of low methodological quality, but a recent randomised controlled trial ( Weinstein et al 2013 ) has shown the efficacy of bracing in decreasing curve progression, thus reducing the necessity of surgery for some patients. Modern surgical techniques are effective in correcting scoliosis, but the surgery is major, with significant risks. Early identification of scoliosis is vital to maximise effective treatment, support the child and family, and optimise holistic health.

Improving the measurement of health-related quality of life in adolescent with idiopathic scoliosis: the SRS-7, a Rasch-developed short form of the SRS-22 questionnaire

Scoliosis Research Society-22 (SRS-22) questionnaire was developed to evaluate health-related quality of life (HRQL) in adolescent idiopathic scoliosis (AIS) patients. Rasch analysis (RA) is a statistical procedure which turns questionnaire ordinal scores into interval measures. Measures from Rasch-compatible questionnaires can be used, similar to body temperature or blood pressure, to quantify disease severity progression and treatment efficacy. Purpose of the current work is to present Rasch analysis (RA) of the SRS-22 questionnaire and to develop an SRS-22 Rasch-approved short form. 300 SRS-22 were randomly collected from 2447 consecutive IS adolescents at their first evaluation (229 females; 13.9 ± 1.9 years; 26.9 ± 14.7 Cobb°) in a scoliosis outpatient clinic. RA showed both disordered thresholds and overall misfit of the SRS-22. Sixteen items were re-scored and two misfitting items (6 and 14) removed to obtain a Rasch-compatible questionnaire. Participants HRQL measured too high with the rearranged questionnaire, indicating a severe SRS-22 ceiling effect. RA also highlighted SRS-22 multidimensionality, with pain/function not merging with self-image/mental health items. Item 3 showed differential item functioning (DIF) for both curve and hump amplitude. A 7-item questionnaire (SRS-7) was prepared by selecting single items from the original SRS-22. SRS-7 showed fit to the model, unidimensionality and no DIF. Compared with the SRS-22, the short form scale shows better targeting of the participants' population. RA shows that SRS-22 has poor clinimetric properties; moreover, when used with AIS at first evaluation, SRS-22 is affected by a severe ceiling effect. SRS-7, an SRS-22 7-item short form questionnaire, provides an HRQL interval measure better tailored to these participants.

Comorbidity influenced health-related quality of life of 390 patients with idiopathic scoliosis at long-term follow-up

BACKGROUND

Comorbidity is common in patients with low back pain and is associated with a poorer prognosis, but this has not been evaluated in patients with idiopathic scoliosis.

AIM

To evaluate comorbidity and health-related quality of life in scoliosis patients.

DESIGN

Cross-sectional study.

SETTING

Outpatient clinic.

POPULATION

Four hundred and ninety-six patients treated with Boston brace for idiopathic scoliosis were invited for long-term follow-up. 390 patients (361 women and 29 men) responded. Mean age was 39.2 (±4.6) years; mean follow-up time 23.4 (±4.3) years after brace weaning. Twenty-eight patients had been operated, 27 of these had long-term follow-up.

METHODS

Radiographs at baseline, brace weaning, and follow-up. Validated questionnaires for evaluation of health-related quality of life including Scoliosis Research Society (SRS-22) and EuroQol (EQ-5D) were applied at follow-up.

RESULTS

122 (31%) patients reported that they had at least one comorbid condition at long-term follow-up. The most common diseases were: asthma (N.=14); migraine (N.=13); lower extremity disorders (N.=10); anxiety/depression (N.=9); allergy (N.=9); cardiovascular disease (N.=8); lumbar disc herniation (N.=8); neck pain or injury (N.=8); and widespread pain (N.=8). Age at bracing and at menarche, compliance, curve sizes, and the number of patients operated, were not different in those who did have and those who did not have comorbidity. Sixty-one percent with comorbidity versus 78% without (P<0.001) had excellent or good back function, and 57% versus 86% worked full-time. Those with comorbidity had significantly (P<0.001) worse SRS-22 scores for pain, function, self-image, and mental health, but not for satisfaction with bracing. Mean EQ-5D was 0.74 with comorbidity and 0.85 (normal for age and gender) without (P<0.001). Curve size was not significantly associated with any health-related quality of life outcome, while operated patients had worse SRS-22 scores for self-image and function (P=0.03).

CONCLUSION

About one-third of middle aged patients with idiopathic scoliosis reported to have at least one comorbid condition. Results indicate that comorbidity influences health related quality of life.

CLINICAL REHABILITATION IMPACT

Comorbidity should be considered when interpreting scores of health-related quality of life in patients with idiopathic scoliosis.

Adolescent idiopathic scoliosis and eating disorders: is there a relation? Results of a cross-sectional study

A recent study suggests a correlation between idiopathic scoliosis in adolescence and eating disorders. However, this does not correspond with our clinical experience in the same population. The aim of this study was to verify the correlation between scoliosis and eating disorders in adolescence. A cross-sectional study was designed including 187 consecutive adolescent girls with a diagnosis of idiopathic scoliosis (mean Cobb angle 26°, range 11-73°, age 15.2±2.5; 24% juveniles, 76% adolescent type) and 93 schoolgirls as controls (age 14.9±1.0). All of the participants answered the Italian validated questionnaire EAT-26 about eating habits in order to identify any eating disorders. Body mass index (BMI) was calculated for all participants and compared to reference data.

STATISTICAL ANALYSIS

chi-square test, Student's t-test, Pearson's correlation coefficient. Only 3 (1.6%; 95% CI -0.2-3.4%) participants in the scoliosis group showed EAT-26 scores suggestive for eating disorders versus 7 (7.5%; 95% CI 2.2-12.9%) in the school population (p<0.05). The BMI was slightly lower (p<0.05) for scoliosis patients (19±0.2) than for school girls (21±0.3). EAT-26 is recognized among the most valid questionnaires for eating disorders and has been widely applied in various countries. By applying this questionnaire, a lower incidence of eating disorders in female scoliosis patients was found than in the general population (using both our own controls and Italian reference values). This contrasts with some expert opinions and a recent study performed in Italy. The low BMI already reported in the literature as being typical of scoliosis participants is confirmed by our data.

Polish validation of Brace Questionnaire

Purpose

The aim of the study was to undertake the process of cultural adaptation of the Brace Questionnaire (BrQ) into Polish.

Methods

The BrQ is an instrument for measuring the quality of life of scoliotic adolescents who are being treated conservatively with wearing a corrective brace. The BrQ consists of 34 Likert-scale items related to eight domains. The translation from the original Greek into Polish was performed. The process of cultural adaptation of the questionnaire was in accordance with the guidelines of the International Quality of Life Assessment Project. It involved 35 adolescents, aged between 10.0 and 16.0 years, all with adolescent idiopathic scoliosis with mean Cobb angle of 35.1 ± 10.6 degrees, and all wearing the same kind of brace (Chêneau orthosis) for more than 3 months. Statistical analysis calculated the reliability (internal consistency), floor and ceiling effects of the BrQ.

Results

The internal consistency was satisfactory; Cronbach’s alpha coefficient was 0.94. There was no floor or ceiling effects.

Conclusions

Polish version of the BrQ is reliable and can be used in adolescents with idiopathic scoliosis wearing the brace to assess their quality of life.

Change of situation of a family with a child treated due to scoliosis

INTRODUCTION AND OBJECTIVE

Scoliosis is a serious clinical problem which requires a systematic physical therapy and control of body balance - treatment from the moment of achieving skeletal maturity by a child. In the situation of neglect of such a management, the deformation of the spine often requires surgical intervention. The role of parents in the process of treatment of a child is undeniable. The study concerns the determination of socio-economic conditions and the engagement of parents with children treated due to scoliosis in Eastern Poland.

MATERIAL AND METHODS

The study was conducted by means of a diagnostic survey. The study group consisted of 193 parents (148 females [76.7%] and 45 males [23.3%]) - a randomly selected sample of the parents of children who participated in scoliosis rehabilitation courses in rehabilitation centres in Eastern Poland. The significance of the relationships between variables was investigated by means of chi-square test for independence. The differences between the empirical and theoretical sample distribution was examined by means of chi-square goodness-of-fit test. The significance level was set at p=0.05.

RESULTS

The study group covered 47.7% of inhabitants of rural areas and small towns, and 52.3% of inhabitants of medium-size and large cities. Respondents possessing university education provided their children a wider profile of health care; however, they neither supervised exercises at home nor paid attention to the maintenance of the normal body posture. The diagnosis of scoliosis in a child rarely affects the relationship between parents. The engagement of parents into rehabilitation treatment of their children is small.

CONCLUSIONS

There is a relationship between social variables and engagement in the treatment of a child with scoliosis. There is a need to create a system of education for parents concerning scoliosis and the consequences of its negligence. The enrolment of a psychologist into the treatment team should be considered, which would provide support for the parents of children suffering from scoliosis.

Psychological aspects of scoliosis surgery in children

Children in the scoliosis surgery ward rarely have the possibility of meeting a psychologist to get support in this difficult situation. As we know, not all children can manage their pain on their own and discharge anger born out of the situation in a constructive way. The purpose of the study is to estimate the strength of individual beliefs conditioning the management of pain (internally), the influence of staff on the management of pain (the influence of others) as well as accidental factors. Also, the objective is to estimate the level of internal and external expression of anger and to estimate the mood of a child before and after the surgery. 52 children between the age of 12.5-17 years old (35 girls and 17 boys) were examined with the Pain Control Beliefs questionnaire by Suzanne Skevington and the Expression of Anger Scale by Oginska. Children who believed their pain was an accidental occurrence reported their mood as being at its lowest, before and after the procedure. Their estimation of the pain experience was the highest. The group taking part in the examination (except for one person) showed a much higher internal expression of anger than that of external which could suggest that they cannot discharge their anger arising out of this difficult situation. It is recommended to expand this research on a bigger group of children and to include psychological support as a standard procedure before and after the surgery for spinal deformity in order to decrease the level of fear and to work with constructive anger discharge.
