Abstract
PURPOSE In the 1960s, Harrington instrumentation (HRI) revolutionized the surgical treatment of adolescent idiopathic scoliosis (AIS). Despite the transition to more innovative techniques, concerns regarding its impact on sagittal alignment, associations with low back pain, and correction loss have consistently persisted. The aim of this meta-analysis is precisely to evaluate the clinical and radiological outcomes, as well as the complications of patients treated with HRI over an extended follow-up period. A systematic search of articles about AIS patients who underwent HRI and reported long-term outcomes (> 10 years) was conducted on electronic databases according to PRISMA guidelines. Data regarding radiographic and clinical outcomes were extracted and meta-analyses were performed. Eleven studies comprising 644 patients were included. The mean follow-up ranged from 10.8 to 51.7 years. Radiographic analysis revealed a decrease in the main curve Cobb angle from 60.6° to 38.3°, with a correction loss of - 9.49° between postoperative and last follow-up. Concerning sagittal parameters, preoperative thoracic kyphosis was 19.65° at last follow-up, and preoperative lumbar lordosis was 42.94°. Additional spine surgeries were required in 42% of patients. Clinical outcomes varied among studies, but overall, HRI patients showed comparable quality of life and function to controls, although a higher incidence of low back pain was reported. Patients who underwent HRI exhibited suboptimal correction of rib deformity and a flattened sagittal spinal alignment. However, they generally displayed favourable long-term functional outcomes. Despite the implant's tendency to reduce lumbar curvature, patients achieved good clinical outcomes and functional scores comparable to age-matched individuals, suggesting that disability is not an inevitable consequence of lumbar flattening.

Abstract
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. LEVEL OF EVIDENCE Level II.

Abstract
PURPOSE To evaluate radiographic and clinical outcomes following revision surgery after HRC fusions. METHODS Single-institution, retrospective study of patients revised following HRC with minimum 2-year follow-up post-revision. Demographics, perioperative information, radiographic parameters, complications, and Oswestry disability index (ODI) scores were collected. Radiographic parameters included global alignment, coronal and sagittal measurements pre and postoperatively, as well as final follow-up time points. RESULTS 26 patients were included with a mean follow-up of 3.3 ± 1.1 years. Mean age was 55.5 ± 7.8 years, BMI 25.2 ± 5.8, and 22 (85%) were females. Instrumented levels increased from 9.7 ± 2.8 to 16.0 ± 2.2. Five (19.2%) patients underwent lumbar pedicle subtraction osteotomies, and 23 (88.4%) had interbody fusions. Patients significantly improved in all radiographic parameters at immediate and final follow-up (p < 0.005), except for thoracic kyphosis and pelvic incidence (p > 0.05). Correction was maintained from immediate postop to final follow-up (p > 0.05). 20 (76.9%) of patients experienced a complication at some point within the follow-up period with the most common being a lumbar nerve root deficit (n = 7). However, only one patient had a nerve root deficit at final follow-up, that being a 4/5 unilateral anterior tibialis function. 5 (19.2%) patients required further revision within a mean of 1.8 ± 1.1 years. On average, patients had an improvement in ODI score by final follow-up (35.6 ± 16.8 vs 25.4 ± 19.8, p = 0.035). CONCLUSION Patients revised for HRCs significantly improve, both clinically and radiographically by final follow-up. This group did have a propensity for distal lumbar root neurological issues, which were common but all patients except for one, recovered to full strength by two-year follow-up.

Abstract
INTRODUCTION Posterior instrumented fusion for progressive adolescent idiopathic scoliosis (AIS) is generally considered to have good outcomes, but very long-term reviews are rare. Data on adjacent segment degeneration (ASD) following posterior instrumented thoracic fusion for AIS are lacking. The primary aim was to assess the incidence of ASD and to correlate this with radiographic measures and patient-reported outcome measures (PROMs). The secondary aim was to assess maintenance of curve correction at very long-term follow-up. METHODS This single-surgeon consecutive case series of 47 AIS patients was identified from a prospectively collated dataset. As the primary outcome, ASD was assessed radiographically using the Mimura grading system. Pulmonary function tests and PROMs were assessed along with secondary radiographic outcome measures. RESULTS Radiographic follow-up was achieved in 77% (36/47) of patients at an average of 21 years (range, 16.5-26.5 years) after surgery. Radiographic evidence of ASD was seen in 64%. PROMs showed a mean Oswestry disability index of 12.1% with an overall Scoliosis Research Society 22 score averaging at 3.7 out of 5. The Coronal Cobb Angle was corrected from an average of 57° preoperatively to 19° immediately postoperatively, deteriorating to 22° at final review, maintaining a 61% curve correction. CONCLUSIONS Radiographic evidence of ASD was found in 64% of the cohort. The patient-reported outcome measures were good, with few limitations to activities.

Abstract
STUDY DESIGN Retrospective case series. OBJECTIVE The purpose of this study is to evaluate the clinical and radiographic outcomes following revision surgery following Harrington rod instrumentation. METHODS Patients who underwent revision surgery with a minimum of 1-year follow-up for flatback syndrome following Harrington rod instrumentation for adolescent idiopathic scoliosis were identified from a multicenter dataset. Baseline demographics and intraoperative information were obtained. Preoperative, initial postoperative, and most recent spinopelvic parameters were compared. Postoperative complications and reoperations were subsequently evaluated. RESULTS A total of 41 patients met the inclusion criteria with an average follow-up of 27.7 months. Overall, 14 patients (34.1%) underwent a combined anterior-posterior fusion, and 27 (65.9%) underwent an osteotomy for correction. Preoperatively, the most common lower instrumented vertebra (LIV) was at L3 and L4 (61%), whereas 85% had a LIV to the pelvis after revision. The mean preoperative pelvic incidence-lumbar lordosis mismatch and C7 sagittal vertical axis were 23.7° and 89.6 mm. This was corrected to 8.1° and 28.9 mm and maintained to 9.04° and 34.4 mm at latest follow-up. Complications included deep wound infection (12.2%), durotomy (14.6%), implant related failures (14.6%), and temporary neurologic deficits (22.0%). Eight patients underwent further revision surgery at an average of 7.4 months after initial revision. CONCLUSIONS There are multiple surgical techniques to address symptomatic flatback syndrome in patients with previous Harrington rod instrumentation for adolescent idiopathic scoliosis. At an average of 27.7 months follow-up, pelvic incidence-lumbar lordosis mismatch and C7 sagittal vertical axis can be successfully corrected and maintained. However, complication and reoperation rates remain high.

Abstract
STUDY DESIGN Prospective case series. OBJECTIVE Determine the efficacy of anterior vertebral body tethering (AVBT) in skeletally immature patients. SUMMARY OF BACKGROUND DATA The value of AVBT is currently unclear given the paucity of available data. METHODS Consecutive skeletally immature patients with idiopathic scoliosis were treated with AVBT between 2012 and 2018 by one of two surgeons working at two independent centers and followed up for >2 years. Data were collected prospectively and supplemented retrospectively where necessary. Outcomes were measured preoperatively, at first erect radiograph (FE), 1-year postoperatively and at most recent follow up (FU). RESULTS One hundred twelve patients underwent 116 primary tethering procedures (108 thoracic and eight lumbar tethers). Four patients had primary tethering of both lumbar and thoracic curves. At surgery mean age was 12.7 ± 1.4 years (8.2-16.7) and Risser 0.5 ± 0.9 (0-3). Follow up was mean 37 ± 9 months (15-64). Preoperative mean coronal Cobb angle of the 130 tethered curves was 50.8° ± 10.2 (31-81) and corrected significantly to 26.6° ± 10.1 (-3-61) at FE radiograph (P < 0.001). Further significant improvement was seen from FE to 1-year, to mean 23.1° ± 12.4 (-37-57) (P < 0.001). There was a small but significant increase between 1-year and FU to 25.7° ± 16.3 (-32-58) (P < 0.001), which appeared to reflect tether breakage. Untethered minor curves were corrected from 31.0° ± 9.5 (3-57) to 20.3° ± 10.3 (0-52) at FU (P < 0.001). Rib hump was corrected from 14.1 ± 4.8 (0-26) to 8.8° ± 5.4 (0-22) at FU (P < 0.01). Twenty-five patients (22%) had 28 complications. Fifteen patients (13%) requiring 18 revision operations including six completed and one awaited fusions. CONCLUSION AVBT of immature cases is associated with satisfactory deformity correction in the majority of cases. However, complication and revision rates suggest the need for improved implants and patient selection. Long-term follow-up remains crucial to establish the true efficacy of this procedure.Level of Evidence: 3.

Abstract
PURPOSE To investigate mid-long-term effects of the lowest instrumented vertebra (LIV) selection on adolescent idiopathic scoliosis (AIS) patients who had posterior spinal fusion (PSF) surgery. METHODS Forty-eight patients were recruited. Inclusion criteria were AIS patients who have had PSF surgery more than 10 years ago. Patients were divided into G1: LIV L3 or higher and G2: LIV L4 or lower. MRI evaluation was classified using Pfirrmann grades. Pfirrmann scores were average of Pfirrmann grades for all unfused discs below LIV. SRS-22r, SF-36, Oswestry Disability Index (ODI) and Modified Cincinnati Sports Activity Scale (MCSAS) were used. RESULTS There were 19 patients in G1 and 29 patients in G2. Demographic parameters showed no significant differences. We found no significant differences in Pfirrmann grades or scores between G1 and G2. There was significant correlation between age and mean Pfirrmann scores (r = 0.546, p < 0.001), Pfirrmann grade for adjacent disc + 1 below LIV (r = 0.475, p = 0.001) and adjacent disc below LIV (r = 0.365, p = 0.011). G2 had significantly lower scores for SRS-22r pain (G1: 4.3 ± 0.5, G2: 4.0 ± 0.6, p = 0.044) and the SF-36 bodily pain (G1: 88.7 ± 12.3, G2: 77.8 ± 18.7, p = 0.018) domains. There were no significant differences in ODI and MCSAS between the two groups. CONCLUSIONS Patients with fusion to L4 or lower had more significant back pain. However, both groups had similar physical function, self-image, satisfaction with treatment, mental health, and functional sports activity. We did not find any significant association between lumbar discs degeneration and the selection of LIV.

Abstract
Limited unilateral instrumentation has been used in the past in the treatment of adolescent idiopathic scoliosis; however, to our knowledge, there are no reported cases with ultra-long follow up regarding this. Our objective is to report on the 43-year follow-up of limited Harrington rod instrumentation for the treatment of a double major adolescent idiopathic scoliosis curve. We describe the patient's initial presentation, including history, physical exam, radiographic findings and clinical decision-making. Initial coronal cobb angle measurements before surgery were: 14° T1-T5, 42° T5-T12, 44° T12-L4. At 43 years of follow up, there was progression (14°>24°, 42°>70°, 44°>50°) of the patient's double major scoliosis curve despite unilateral, limited Harrington rod instrumentation from L4-S1. The patient was treated with a T3-pelvis instrumentation and fusion and posterior column osteotomies. To our knowledge, this is the longest follow-up and subsequent revision of a patient undergoing limited, unilateral Harrington rod instrumented fusion for the treatment of a double major adolescent idiopathic scoliosis curve.

Abstract
PURPOSE To report radiographic and functional outcomes, with an average follow-up of 20 years, of adolescents treated surgically for thoracic idiopathic scoliosis by hybrid construct using only pedicular screws for the distal fixation. METHODS We retrospectively reviewed 109 patients. Radiographic data were evaluated on fullspine radiographs (Cobb angle, pelvic incidence, sacral slope, pelvic tilt, thoracic kyphosis, lumbar lordosis). Clinical data were evaluated with ODI, SF-12, SRS-30 and Analog Pain Scale. Disc height and listhesis below the arthrodesis were measured. RESULTS We analyzed 90 women and 19 men with a mean age of 16.9 y.o. at surgery. Radiographic data were assessed for 46 patients after 17.4 years. Mean preoperative Cobb angle was 58°, mean correction 40.1% with 5.3° of loss at final FU. Lumbar lordosis and thoracic kyphosis increased significantly at last FU. Degenerative changes below the arthrodesis were reported in 5 cases. Clinical data were assessed for 42 patients after 19.9 years: SRS-30 3.8; ODI 12.3%; SF-12 PCS 48.6 and MCS 46. Low back pain was reported in 69% of cases with low intensity (3.1). The lowest instrumented vertebrae did not influence significantly the functional outcome. CONCLUSIONS The correction of thoracic AIS with lumbar or thoracolumbar pedicle screw instrumentation provides good radiological and clinical outcomes at very long term. The reduction in the coronal plane is stable; the HRQoL is quite as good as the general population. The degenerative evolution below remain relatively rare, therefore global sagittal balance is not modified.

BMC Musculoskelet Disord 2021; 22:106. [PMID: 33485304 PMCID: PMC7825157 DOI: 10.1186/s12891-021-03953-y] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/24/2020] [Accepted: 01/04/2021] [Indexed: 11/12/2022] Open
Abstract
Background The severe rigid deformity patients with pulmonary dysfunction could not tolerate complicated corrective surgery. Preoperative traction are used to reduce the curve magnitude and improve the pulmonary function before surgery, including halo-gravity traction (HGT) and halo-pelvic traction (HPT). The present study aimed to retrospectively compare the radiographic, pulmonary and clinical outcomes of preoperative HGT and HPT in severe rigid spinal deformity with respiratory dysfunction. Methods 81 cases of severe rigid kyphoscoliosis treated with preoperative traction prior to corrective surgery for spinal deformity between 2016 and 2019 were retrospectively reviewed. Two patient groups were compared, HPT group (N = 30) and HGT group (N = 51). Patient demographics, coronal and sagittal Cobb angles and correction rates, pulmonary function, traction time, osteotomy grade, and postoperative neurological complications were recorded for all cases. Results The coronal Cobb angle was corrected from 140.67 ± 2.63 to a mean of 120.17 ± 2.93° in the HGT group, and from 132.32 ± 4.96 to 87.59 ± 3.01° in the HPT group (mean corrections 15.33 ± 1.53 vs. 34.86 ± 3.11 %) (P = 0.001). The mean major sagittal curve decreased from 134.28 ± 3.77 to 113.03 ± 4.57° in the HGT group and from 129.60 ± 8.45 to 65.61 ± 7.86° in the HPT group (P < 0.001); the mean percentage corrections were 16.50 ± 2.13 and 44.09 ± 9.78 % (P < 0.001). A significant difference in the pulmonary function test results was apparent between the two groups; the mean improvements in the FVC% of the HGT and HPT groups were 6.76 ± 1.85 and 15.6 ± 3.47 % (P = 0.024). The HPT group tended to exhibit more FEV% improvement than the HGT group, but the difference was not significant (5.15 ± 2.27 vs. 11.76 ± 2.22 %, P = 0.91). Conclusions Patients with severe rigid kyphoscoliosis who underwent preoperative HPT exhibited better radiographic correction of the deformity, and pulmonary function, and required fewer osteotomies compared to the HGT group. Thus, HPT may be useful for severe rigid spinal deformity patients with pulmonary dysfunction.

Abstract
Skip pedicle screw fixation for adolescent idiopathic scoliosis (AIS) requires fewer screws and can reduce the risk of neurovascular injury as compared with segmental pedicle screw fixation. However, the long-term impact of screw number reduction on correction and clinical results is unclear. This study examined the 10-year post-operative outcomes of skip pedicle screw fixation for patients with AIS. We reviewed the outcomes of 30 patients who underwent skip pedicle screw fixation for AIS. Radiological and clinical findings were assessed before and immediately, 2 years, and 10 years after surgery in the remaining 25 patients. The mean Cobb angle of the main curve preoperatively and immediately, 2 years, and 10 years post-operatively was 59.4°, 23.4°, 25.8°, and 25.60°, respectively, and was significantly improved at all post-surgical time points (all p < 0.001). The mean correction rate immediately after surgery was 60.8%, and the correction loss rate at the observation end point was 4.8%. The Cobb angle of the lumbar curve was significantly improved immediately after surgery, and the correction persisted until 10 years post-operatively. Remarkable gains were observed for most Scoliosis Research Society-22 patient questionnaire sub-scores at the final follow-up versus preoperative assessments. In conclusion, good correction of the AIS deformity by skip pedicle screw fixation was well maintained over a long follow-up period of 10 years, with clinically meaningful gains in Society-22 patient questionnaire sub-scores.

Abstract
STUDY DESIGN A retrospective longitudinal follow-up study. OBJECTIVES The aim of this study is to evaluate the health-related quality of life (HRQOL) of post-operative AIS patients from less than 1 year to over 30 years using SRS-22 questionnaire. Some of our AIS patients who operated since the establishment of the scoliosis clinic have passed the 30th year. The HRQOL of patients many years after surgery had yet to be summarized and reported. METHODS SRS-22 questionnaire was conducted by 254 operated patients between the year 2016 and 2018. All post-operative patients who visited a specialized clinic for annual check-up within the study period completed SRS-22. The number of years since surgery per questionnaire was grouped per 1 year until the 10th year, and per 5 years afterwards. The 6 SRS-22 domain scores (function, pain, self-image, mental, satisfaction, mean) were compared across time period. RESULTS All SRS-22 domain scores in post-operative patients, except "Self-image", were relatively stable in the first 5 years until a steady drop starting from the 10th year. "Self-image" was statistically lower than "Function" and "Pain" from the 10th years to more than 30 years. CONCLUSIONS HRQOL of post-operative AIS patients remained stable until 10 years after surgery and was steadily decreasing. "Self-image" was consistently and statistically lower than the other scores. Patients who have surgically treated for more than 25 years are now at their perimenopause. Specific medical and psychosocial cares for this kind of patients are recommended to provide during the routine medical check-up. LEVEL OF EVIDENCE II.

Abstract
Spinal fusion surgery is performed all over the world to help patients with cervical and thoracolumbar pathology. As outcomes continue to improve in patients with spine-related pathology, it is important to understand how we got to modern day spinal fusion surgery. Scientific innovations have ranged from the first spinal fusions performed with basic instrumentation in the late nineteenth century to contemporary tools such as pedicle screws, bone grafts, and interbody devices. This article tracks this technological growth so that surgeons may better serve their patients in treating spine-related pain and disability.

Abstract
STUDY DESIGN Prospective registry. The evolution of spinal instrumentation has provided better outcomes in adolescent idiopathic scoliosis (AIS); however, there is a paucity of reliable prospective information on 10-year post-operative outcomes of modern surgical techniques. METHODS A prospective multicenter registry of patients who had surgical correction of AIS was reviewed. Patients with major thoracic scoliosis (Lenke types 1-4) operated on between 1997 and 2007, with 10-year post-operative follow-up data were included. Radiographic and clinical outcomes including Scoliosis Research Society (SRS)-22 scores and revision surgeries were evaluated. RESULTS One hundred and seventy-four patients (mean 25.0 years of age at most recent evaluation) were included. Pedicle screw constructs were used in 102 patients (58%), hook or hybrid constructs in 22 (13%), and anterior screw-rod constructs in 50 (29%). The mean pre-operative thoracic Cobb angle was corrected from 53° to 18° initially. At 10-year follow-up, the mean thoracic curve was 22° (mean 57% correction), with 29 patients (16.7%) having loss of correction (LOC) ≥ 10°. There were a total of 14 revision surgeries performed in 13 patients (7.5%). SRS-22 pain (p = 0.035), self-image (p < 0.001), and total scores (p < 0.001) significantly improved at 2-year follow-up. The mean pain score at 10-year follow-up was similar to pre-operative scores and lower (more pain) than previously published mean scores of normal adults aged 20-40 years (p < 0.05). CONCLUSIONS Spinal fusion patients report SRS-22 quality of life 10 years after scoliosis surgery that is minimally reduced compared to healthy peers and substantially better than an un-operated cohort of comparably aged scoliosis patients. Adolescents with thoracic idiopathic scoliosis should expect little if any change in their health-related quality of life compared to before surgery, high satisfaction, and a 7.5% chance of revision surgery 10 years after their index spinal fusion.

Abstract
Extremely severe scoliosis patients, especially main thoracic Cobb' s angle >150°, often have severe thoracic deformity and pulmonary dysfunction, even the scoliosis is reduced by halo-pelvic traction, the improvement of pulmonary function is not satisfactory, the risk of spinal osteotomy in the next stage is still very high and left with obvious thoracic deformity. How to further improve the pulmonary function and appearance of these patients is a difficult problem to be solved.Twenty extremely severe scoliosis patients with severe pulmonary dysfunction who underwent concave-side thoracoplasty in our hospital from September 2014 to September 2017 were included, data of thoracic volume and pulmonary function were collected before and after operation. The pulmonary function value reported was predicted forced vital capacity (FVC%), T-test was used to analyze the changes of the data by the statistical software SPSS21.0.The 20 patient's averaged Cobb's angle of main thoracic was 163° ± 8° at admission and all of them with severe pulmonary dysfunction before concave-side thracoplasty. After operation, the thoracic volume of patients increased by 500.9 ± 222.9 mL, FVC% increased by 8.9% ± 7.5%. Both the difference has statistical significance (P < .01).Concave-side thoracoplasty based on the halo-pelvic traction cannot only enlarge the volume of the concave thoracic cavity, lighten the compression of lung and further improve the pulmonary function of extremely severe scoliosis, but also can strengthen the correction of scoliosis and spinal rotation. Therefore, it is a safe and effective surgical approach.

Abstract
STUDY DESIGN Longitudinal cohort. OBJECTIVES To determine the patient-reported functional outcomes and need for related surgical procedures in a US cohort of adolescent idiopathic scoliosis (AIS) patients with minimum 20-year follow-up. SUMMARY OF BACKGROUND DATA There is limited information regarding the long-term outcomes of scoliosis treatment in the US population. METHODS A novel population of patients who underwent pediatric treatment for AIS with minimum 20-year follow-up was identified. Search of a single-center diagnostic registry generated 337 patients who fulfilled the inclusion criteria (AIS, curve magnitude >35°, and childhood treatment with bracing, surgery, or observation from 1975 to 1992). Any additional spine surgery as well as EQ5D, ODI, SRS 22, SAQ were determined. A total of 180 patients were included (mean of 30-year follow-up, range 20-37). Childhood treatment entailed bracing (41 patients), surgery (103 patients), and observation (36 patients). RESULTS During the study period, only 1 of the 41 bracing patients underwent additional scoliosis-related spine surgery, whereas 5 of the 36 patients in the observation cohort underwent scoliosis surgery as adults. Seven of 103 childhood surgical patients required additional revision surgery as adults. Fifteen patients (4 braced, 7 fusion, and 4 observed) underwent chest wall surgery as adults. SRS scores were around 10% worse compared to population-based controls, with the exception of SRS mental health scores, which were similar to controls. Overall, 5.6% of patients were on disability, with no difference between operative and nonoperative groups. CONCLUSION We found a low rate of adult scoliosis surgery in the braced population, and a low rate of revision surgery at the 30-year follow-up in patients undergoing spine fusion for AIS between 1975 and 1992. No detected differences in patient-reported outcomes were found between the braced, surgical, and observed populations at a mean of 30 years' follow-up. LEVEL OF EVIDENCE Level III, therapeutic.

Abstract
BACKGROUND Health-related quality of life in adults with idiopathic scoliosis diagnosed before maturity has been reported to be similar between brace-treated and surgically treated individuals. The aim of this study was to compare health-related quality of life in untreated, brace-treated, and surgically treated adults with idiopathic scoliosis diagnosed before skeletal maturity. Subgroup analyses were performed on the basis of age at the time of the study, age of onset, surgical characteristics, and curve magnitude. METHODS We included 1,187 adults with juvenile or adolescent idiopathic scoliosis with a mean age (and standard deviation) of 38.8 ±12.7 years. Of these, 347 were untreated, 459 had been brace-treated, and 381 had been surgically treated. The Scoliosis Research Society-22r (SRS-22r) and EuroQol 5-Dimensions (EQ-5D) were used. Statistical analyses were performed using analysis of covariance. RESULTS The mean SRS-22r subscore was 4.15 ± 0.59 points for the untreated group, 4.10 ± 0.57 points for the previously braced group, and 4.01 ± 0.64 points for the surgically treated group (p = 0.007 adjusted for age and sex). The EQ-5D index was 0.82 ± 0.20 for the untreated group, 0.82 ± 0.20 for the previously brace-treated group, and 0.79 ± 0.24 for the surgically treated group (p = 0.026, adjusted for age and sex). Brace cessation was at the mean age of 16.2 ± 1.5 years, and the surgical procedure had been performed at the mean age of 15.3 ± 2.1 years. A more caudal fusion was associated with a lower SRS-22r subscore and EQ-5D index. No differences were observed when comparing individuals with juvenile or adolescent onset scoliosis (all p > 0.05). CONCLUSIONS Untreated adults with idiopathic scoliosis had similar health-related quality of life to previously brace-treated individuals, and they had marginally higher health-related quality of life compared with surgically treated individuals. Therefore, both surgical and brace treatments for idiopathic scoliosis could be considered successful from a health-related quality-of-life point of view in adulthood. The age of onset of idiopathic scoliosis does not seem to influence quality of life in adulthood. LEVEL OF EVIDENCE Therapeutic Level III.

Abstract
STUDY DESIGN A retrospective comparative study. OBJECTIVE The aim of this study was to evaluate the difference in trends of disc degeneration (DD) at lower unfused segments (LUS) for postoperative patients who have gone through spinal instrumentation at 10-year follow-up with the natural progression of idiopathic scoliosis. SUMMARY OF BACKGROUND DATA Studies that used magnetic resonance imaging (MRI) state that DD rates at LUS are higher than in the normal population. However, current studies do not prove that surgery is the most effective clinical method to treat idiopathic scoliosis, as no existing report compares the rates of DD with the natural history of idiopathic scoliosis. METHODS Female patients diagnosed of scoliosis were divided into three groups: 1) surgical group: postoperative 10-year patients with severe scoliosis before operation; 2) mild scoliosis group: with comparatively equal scoliosis to postoperative patients of the same age at 10 years follow-up; 3) severe scoliosis group: without any record of corrective surgery under the assumption that the scoliosis of the surgical group have progressed according to natural history. RESULTS MRI findings of the surgical group show DD in 32 patients (62.7%) where the highest rate of DD occurred at L5/S. In the mild scoliosis group, 21 patients (47.7%) had DD, with higher rates at L4/5 and L5/S. DD was most common in L3/4 and L4/5 in the severe scoliosis group where 27 patients (81.8%) had DD. As such, DD rates were significantly higher in the severe scoliosis group than the surgical group at the same spinal level. The same was true for the existence of low back pain, where the severe scoliosis group had greater incidence of low back pain than the surgical group. CONCLUSION Corrective surgeries were able to reduce the incidence of DD. Radiological analysis also suggests that surgical intervention is a clinically feasible treatment for idiopathic scoliosis patients. LEVEL OF EVIDENCE 3.

Abstract
Introduction The purpose of this study was to investigate the long-term incidence of lumbar disc degeneration and Modic changes in the non-fused segments of patients with adolescent idiopathic scoliosis (AIS) who previously underwent spinal fusion. Methods Study subjects consisted of 252 patients with AIS who underwent spinal fusion between 1968 and 1988. Of 252 patients, 35 subjects underwent lumbar spine MRI and whole spine X-ray examination. The mean patient age at the time of follow-up was 49.8 years, with an average follow-up period of 35.1 years. We classified the subjects into two groups based on the lowest fused vertebra: H group whose lowest fused vertebra was L3 or higher levels and L group whose lowest fused vertebra was L4 or lower levels. Results The L group had significantly advanced disc degeneration on MRI. There was no significant difference between two groups in Modic changes. The L group showed less lumbar lordosis than the H group (H group: 48.1 degrees; and L group: 32.1 degrees) and greater SVA (H group: 1.2 cm; and L group: 5.5 cm). Conclusions In AIS patients, 35 years after spinal fusion surgery on average, we evaluated lumbar disc degeneration and Modic changes of the non-fused segments. In patients with the lowest fusion level at L4 or lower, there were reduced lumbar lordosis, considerable SVA imbalance, and severe disc degeneration compared with those with the lowest fusion level at L3 or higher. The lowest fusion level at L3 or higher is recommended to reduce disc degeneration in midlife.

Abstract
STUDY DESIGN Case control comparative series. OBJECTIVE Describe surgical range adolescent idiopathic scoliosis (AIS) patients electing to forgo surgery and compare health-related quality-of-life outcomes to a similar cohort of operated AIS patients by the same single surgeon. SUMMARY OF BACKGROUND DATA No data have been published either documenting SRS-22r scores of nonoperated patients with curves ≥40° or comparing these scores to a demographically similar operated cohort. METHODS Individuals with curves ≥40°, age ≥18 years, and electing to forgo surgery were identified. All patients completed an SRS-22r questionnaire. This nonoperated cohort's SRS-22r scores were compared to those of a large demographically similar cohort operated by the same surgeon. Group differences between the SRS-22r scores were evaluated by comparing these to published Minimal Clinically Important Differences (MCID) for the SRS-22r. RESULTS One hundred ninety subjects with nonoperated curves were compared to 166 individuals who underwent surgery. The nonoperated cohort averaged 23.5 years of age, averaged 7.7 years since curve reached 40°, and had an average 50° Cobb angle at last follow-up. No statistical significant differences were found between the groups on the Pain, Function, or Mental Health domains of the SRS-22r. Statistically significant differences in favor of the operative cohort were found for self-image, satisfaction, and total score. The observed group differences did not meet the established thresholds for minimal clinically important differences in any of the domain scores, the average total score, or raw scores. CONCLUSION There are no meaningful clinically significant differences in SRS-22r scores at average 8-year follow-up between AIS patients with curves ≥40° treated with or without surgery. These data in conjunction with an absence of long-term evidence of serious medical consequences with nonsurgical management of curves ≥40° should encourage surgeons to reevaluate the benefits of routine surgical care.

Abstract
PURPOSE Our previous study reported a good health-related quality of life (HRQOL) in adolescent idiopathic scoliosis (AIS) patients 21 years or more after surgery. The purpose of this study is to investigate midlife changes in HRQOL among AIS patients who passed further 5 years from the previous survey. METHODS Subjects were 252 individuals who underwent spinal fusion for AIS between 1968 and 1988. The survey was administered twice-in 2009 and in 2014 using Scoliosis Research Society Patient Questionnaire (SRS-22). We analysed survey responses from 42 individuals (39 females, 3 males) who responded to both surveys. RESULTS The average scores for each respective domain of the SRS-22 in 2009 and 2014, respectively, were: function, 4.3 and 4.2; pain, 4.3 and 4.3; self-image, 3.0 and 2.9; mental, 3.9 and 3.8; satisfaction, 3.6 and 3.5. There were no significant differences in any domain of the SRS-22 between 2009 and 2014. Comparing non-fused segments of the lumbar spine of patients with fewer than four discs remaining with patients with four discs or more remaining, SRS-22 satisfaction score decreased more in patients with fewer than four discs (change in patients with four discs or more: -0.02; change in patients with fewer than four discs: -0.38; P = 0.05). CONCLUSION Each SRS-22 subscore was similar between 2009 and 2014 surveys. Those scoliosis patients who underwent spinal fusion during adolescence had good HRQOL scores in midlife. Even after five years passed, good conditions were maintained.

Abstract
PURPOSE To prospectively evaluate the quality of life (QoL), functionality, and body image of subjects who had undergone surgery for adolescent idiopathic scoliosis (AIS) 5-12 years previously, and to identify the outcome predictors. METHODS The sample consisted of 87 patients for whom follow-up data were available out of a series of 91 patients who had surgery for AIS between 2002 and 2009. We assessed the preoperative, 1-year postoperative, and 5-year or more postoperative SF-36 and SRS-23 questionnaire scores. Longitudinal clinical and radiographic data also were evaluated. Changes in the patient-oriented outcomes were compared with age and sex-adjusted normative values. A multiple regression analysis was used to identify possible outcome predictors. RESULTS Preoperatively, patients had impaired QoL, functionality, and body image compared to age- and sex-matched healthy controls. Surgery led to significant improvement of the SF-36 and SRS scores at the one-year and final control date, but the final scores on SF-36's physical indexes were lower than control subjects' scores. No clinically relevant differences with the normative values were detected in the final SRS scores. The height of the residual rib hump negatively predicted the total SRS and self-image scores; a more caudal level of fusion correlated with more postoperative pain. CONCLUSIONS Patients who underwent surgery for AIS a minimum of 5 years earlier had impaired self-reported physical QoL compared to control subjects, but they nevertheless performed better than before their surgery. Greater size of the residual hump and greater distal extension of the fusion area are negatively correlated with final self reported outcome.

Abstract
OBJECTIVE The objective is the description and summary of the current state of idiopathic scoliosis treatment with physical therapy based on new scientific knowledge and concluded from more than 15 years of experience as a leading physician in two well-known clinics specializing in the conservative treatment of scoliosis. MATERIALS AND METHODS Based on current scientific publications on physical therapy in scoliosis treatment and resulting from the considerable personal experience gained working with conservative treatment and consulting scoliosis patients (as inpatients and outpatients), the current methods of physical therapy have been compared and evaluated. RESULTS Physical therapy according to Schroth and Vojta therapy are at present the most common and effective methods in the physical treatment of idiopathic scoliosis. These methods can be applied during inpatient or outpatient treatment or intensified in the practice of specialized therapists. DISCUSSION As there are only a few scientific studies on this subject, the author's findings are based mainly on his own experiences of the conservative treatment of idiopathic scoliosis. Athough these experiences are the results of over 15 years of working in the field of therapy, and the Schroth method in combination with corrective bracing presents highly promising results, it would nevertheless be desirable to conduct detailed scientific studies to verify the effectiveness of conservative treatment.

Abstract
STUDY DESIGN Longitudinal cohort. OBJECTIVES To evaluate the long-term radiologic outcomes in adolescent idiopathic scoliosis (AIS) patients more than 22 years after treatment. SUMMARY OF BACKGROUND DATA Although treatment for AIS is prophylactic and is aimed at preventing curve progression, very few studies report long-term outcomes of treatment. METHODS AIS patients treated with Boston brace or posterior spinal fusion (PSF) with Harrington-dorso-transverse traction (DTT) instrumentation from 1983 to 1990 were requested to return to clinic. Subsequently, 36-inch standing radiographs were obtained after patient consent. Cobb angles were compared with pretreatment and immediate posttreatment radiographs. Any evidence of adjacent-level disease or local kyphosis was also noted. RESULTS One hundred fifty-nine (78%) of 219 patients were available for follow-up, 66 braced and 93 surgical. There were 85 females with an average age at surgery of 14.3 years and an average age at follow-up of 37.6 years. The mean length of follow-up was 24.5 years (range, 22-30 years). There was a statistically significant curve progression of 2.9° in the PSF group. There was a greater degree of curve progression in the braced group (5.5°), but this was not statistically significant. Proximal segment degeneration was seen in 8 (5%), 2 in the brace cohort and 6 in the PSF cohort. Distal segment degeneration was seen in 26 (16%) patients, 4 treated with brace and 22 treated with PSF. No patient developed proximal junction kyphosis. Three patients in the PSF cohort required additional surgery for distal adding-on. Four patients had a noncontiguous L5-S1 fusion, three from the PSF cohort and one from the braced cohort. CONCLUSION In this cohort with an average follow-up of 24.5 years, with 78% available for follow-up, both the braced and surgically treated patients had a very small degree of curve progression, with a small incidence of distal segment degeneration and reoperation.

Abstract
STUDY DESIGN A systematic review of studies reporting pain as a long-term outcome after spinal fusion surgery for treatment of adolescent idiopathic scoliosis. OBJECTIVE To identify studies that report pain after spinal fusion surgery for scoliosis based on the distal extent of fusion and to combine results to determine if there is an increased incidence of back pain in patients treated with fusion to the lower lumbar spine. SUMMARY OF BACKGROUND DATA The methods and results of existing studies are inconsistent and only occasionally reach statistical significance. No thorough review of the available information has been published. METHODS An electronic literature search was performed to identify studies that met predetermined eligibility criteria. Data extracted included number of cases fused to L3 or above, to L4 or L5, and the number of those cases experiencing pain. Further, when possible, the pain variable was stratified into severe or mild categories to allow a more specific subanalysis. RESULTS Eight studies met inclusion criteria. The meta-analysis for occurrence of pain, the primary outcome, resulted in a final odds ratio of 1.29 (95% CI 0.91-1.82, n = 1,155). When pain was stratified according to severity and only those cases in the severe category considered for meta-analysis, the resulting odds ratio was 1.43 (95% CI 0.72-2.82, n = 900). Neither analysis reached statistical significance. CONCLUSIONS Although there was a trend toward increased pain in patients whose fusion extended to L4 or L5, there was no statistically significant association between the distal level of fusion and incidence of subsequent back pain, both with and without stratification according to severity of back pain. Because of the limitations of published research, the effect of fusion into the lower lumbar spine on back pain is unknown. Higher quality studies with long-term follow-up and consistent reporting of outcomes are needed.

Abstract
STUDY DESIGN Review and statistical analysis of studies evaluating the effect of surgery on the health-related quality of life of adolescents with adolescent idiopathic scoliosis, using Scoliosis Research Society (SRS) outcomes. OBJECTIVE Apply published minimum clinical important differences (MCID) values for the SRS22r questionnaire to the literature to identify what areas of health-related quality of life are consistently affected by surgery and whether changes are clinically meaningful. SUMMARY OF BACKGROUND DATA The interpretation of published studies using the SRS outcomes has been limited by the lack of MCID values for the questionnaire domains. The recent publication of these data allows the clinical importance of any changes in these studies to be examined for the first time. METHODS A literature search was undertaken to locate suitable studies that were then analyzed. Statistically significant differences from baseline to 2 years postoperatively were ascertained by narratively reporting the analyses within included studies. When possible, clinically significant changes were assessed using 95% confidence intervals for the change in mean domain score. If the lower bound of the confidence intervals for the change exceeded the MCID for that domain, the change was considered clinically significant. RESULTS The numbers of cohorts available for the different analyses varied (5-16). Eighty-one percent and 94% of included cohorts experienced statistically significant improvements in pain and self-image domains. In terms of clinical significance, it was only self-image that regularly improved by more than MCID, doing so in 4 of 5 included cohorts (80%) compared with 1 of 12 cohorts (8%) for pain. No clinically relevant changes occurred in mental health or activity domains. CONCLUSION Evidence suggests that surgery can lead to clinically important improvement in patient self-image. Surgeons and patients should be aware of the limited evidence for improvements in domains other than self-image after surgery. Surgical decision-making will also be influenced by the natural history of adolescent idiopathic scoliosis.

Abstract
STUDY DESIGN Meta-analysis on mid- to long-term outcomes in adolescent idiopathic scoliosis after instrumented posterior spinal fusion. OBJECTIVE To compare mid- to long-term outcomes and complications of the most commonly used instrumentation systems in adolescent idiopathic scoliosis. SUMMARY OF BACKGROUND DATA A meta-analysis of mid- to long-term results of different methods of instrumentation, including the most currently used all-pedicle screw construct, is lacking. METHODS A structured literature review was conducted for studies concerning management of patients with adolescent idiopathic scoliosis with instrumented posterior fusion. Pooled means, standard deviations, and sample sizes were either identified or calculated on the basis of the results of each study. RESULTS Meta-analyses were performed on outcomes from 27 studies. Overall, 1613 patients who had been treated with Harrington rods, 361 patients who had undergone Cotrel-Dubousset instrumentation, and 298 patients who managed with all-pedicle screw constructs were reviewed. The mean follow-up was 14.9 years. Cotrel-Dubousset and pedicle screw instrumentations achieved a significantly greater degree of correction of the thoracic curve than Harrington rods (40.3° vs. 14.7°; P < 0.001 and 21.9° vs. 14.7°; P = 0.005, respectively). Cotrel-Dubousset technique achieved a significantly higher degree of correction than all-pedicle screw construct in both the thoracic (40.3° vs. 21.9°, respectively; P < 0.001) and lumbar curves (37.2° vs. 16°, respectively; P < 0.001). Similarly, Cotrel-Dubousset construct achieved a greater correction of both thoracic kyphosis (33.5° vs. 23°, respectively; P < 0.001) and lumbar lordosis (46° vs. 50.7°, respectively; P = 0.002) than pedicle screws. All-pedicle screw fixation was associated with the lower risk of pseudarthrosis, infection, neurological deficit, and reoperation. CONCLUSION This study confirms the negative effect of Harrington rods on sagittal alignment. We further found that the degree of correction in the coronal and sagittal planes was higher after Cotrel-Dubousset instrumentation than all-pedicle screw fixation. All-pedicle screw constructs offered the lower risk of mid- to long-term complications and revision surgery.

OBJECTIVE To compare health-related quality of life and low back pain of healthy subjects with those of patients with nonidiopathic scoliosis (non-IS) and idiopathic scoliosis (IS) 21 years or more after surgery. SUMMARY OF BACKGROUND DATA There have been a very small number of reports on long-term results of surgery for non-IS. There have not been any reports that compare non-IS, IS, and healthy subjects. METHODS The subjects with scoliosis were 602 patients who had undergone surgery between 1968 and 1988. The Scoliosis Research Society Patient Questionnaire (SRS-22), Roland-Morris Disability Questionnaire (RDQ), and our institution's original questionnaire were used for evaluating long-term clinical outcomes. The 136 respondents consisted of 56 patients with non-IS (non-IS group) and 80 patients with IS (IS group). The control group (CTR group) consisted of 80 healthy volunteers who were age- and body mass index-matched to the scoliosis groups. RESULTS In the SRS-22, the 3 groups had no significant differences in pain and mental health. For function and self-image, the non-IS group and the IS group had a significantly lower score than the CTR group. In the RDQ, the non-IS group had significantly more severe low back pain than the CTR group. There was no significant difference in low back pain between the non-IS group and IS group or between the IS group and CTR group. The non-IS group had a significantly lower marriage rate than the IS and CTR groups. CONCLUSION The patients with non-IS and IS had similar health-related quality of life and low back pain. The patients with non-IS were found to have lower function and self-image in the SRS-22 questionnaire and more severe low back pain in the RDQ than healthy subjects. The patients with non-IS had a significantly lower marriage rate than the other 2 groups.

Cotrel-dubousset instrumentation for the correction of adolescent idiopathic scoliosis. Long-term results with an unexpected high revision rate. SCOLIOSIS 2012; 7:13. [PMID: 22710010 PMCID: PMC3479423 DOI: 10.1186/1748-7161-7-13] [Citation(s) in RCA: 21] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/03/2012] [Accepted: 05/26/2012] [Indexed: 12/03/2022]
Abstract
Background For many years, the CD instrumentation has been regarded as the standard device for the surgical correction of adolescent idiopathic scoliosis (AIS). Nevertheless, scientific long-term results on this procedure are rare. Therefore, we conducted a retrospective follow-up study of patients treated for AIS with CD instrumentation and spondylodesis. Methods A total of 40 patients with AIS underwent CD instrumentation in our department within 3 years and between 1990 and 1992. For the retrospective analysis, first all the patient documents were reviewed, and pre-/postoperative X-ray images as well as those at the latest follow-up were analysed. Furthermore, it was attempted to conduct a clinical survey using the SRS-24 questionnaire, which was sent to the patients after a preceding announcement on the phone. Results Radiologically, the frontal main curvature was improved from a preoperative angle of 69.2° to a postoperative angle of 35.4°, and the secondary curvature was improved from a preoperative angle of 42.6° to a postoperative angle of 20.5°. The latest radiological follow-up at average 57.4 months post surgery showed an average loss of correction of 9.6° (main curvature) and 4.6° (secondary curvature), respectively. Within the first 30 days post surgery, 3 out of 40 patients (7.5%) received early operative revision for the dislocation of hooks or rods. At an average of 45.7 months (range 11 to 142 months), 19 out of 40 patients (47.5%; including 2 patients with early revision) received late operative revisions: The reasons were late infection (10 out of 40 patients; 25%) with the development of fistulae (7 cases) or putrid secretion (3 cases), which was resolved with the complete removal of instrumentation after all. The average time until revision was 35.5 months (range 14 to 56 months) after CD instrumentation. Furthermore, complete implant removal was necessary in 8 out of 40 patients (20%) for late operate site pain (LOSP). The average time until removal of instrumentation was 62.7 months (range 18 to 146 months) post surgery; and one patient received partial device removal for prominent instrumentation 11 months post surgery. Altogether, only 22 out of 40 CD instrumentations (55%) were still in situ. After an average period of 14.3 years post surgery, it was possible to follow-up 14 out of 40 patients (35%) using the SRS-24 questionnaire. The average score was 93 points, without showing significant differences between patients with or without their instrumentation in situ. Conclusions Retrospectively, we documented for the first time a very high revisions rate in patients with AIS and treated by CD instrumentation. Nearly half of the instrumentation had to be removed due to late infection and LOSP. The reasons for the high rate of late infections with or without fistulae and for LOSP were analysed and discussed in detail.

STUDY DESIGN A case control study. OBJECTIVE To determine the clinical outcome of middle-aged patients surgically treated for adolescent idiopathic scoliosis and to compare their outcomes with assessments of age- and sex-matched healthy controls. SUMMARY OF BACKGROUND DATA Several long-term follow-up studies have been published on the clinical outcomes of surgical treatment for adolescent idiopathic scoliosis in patients who have reached their 20s or 30s. However, clinical outcomes in patients who have reached middle age remain unknown. METHODS This study included 256 patients surgically treated for adolescent idiopathic scoliosis (AIS) between 1968 and 1988. The Scoliosis Research Society Patient Questionnaire (SRS-22) and Roland-Morris Disability Questionnaire (RDQ) were used for evaluating long-term clinical outcomes. Sixty-six (25.8%; 62 females, 4 males; mean age, 46.0 years [range 34-56]) of the 256 patients responded to the questionnaires. The mean follow-up period was 31.5 (range 21-41) years. Seventy-six healthy age- and sex-matched individuals with neither a history of spinal surgery nor scoliosis were selected as a control (CTR) group. RESULTS On the basis of the SRS-22 responses, AIS patients had significantly decreased function (AIS: 4.3 ± 0.6, CTR: 4.7 ± 0.5, P < 0.01) and decreased self-image (AIS: 3.0 ± 0.8, CTR: 3.7 ± 0.5, P < 0.01) in comparison with the controls, but the 2 groups were similar with respect to pain (AIS: 4.3 ± 0.6, CTR: 4.2 ± 0.5, P = 0.14) and mental health (AIS: 3.9 ± 0.9, CTR: 3.7 ± 0.7, P = 0.14). The RDQ responses indicated that low back pain was not significantly increased in the AIS group compared with the CTR group (AIS: 1.8 ± 3.5, CTR: 1.4 ± 3.1, P = 0.36). CONCLUSION Surgery had no demonstrable adverse effects on pain or mental health in these middle-aged AIS patients 21-41 years after surgery, although the AIS patients did have significantly lower function and lower self-image than the controls.

Abstract
Introduction Spontaneous fractures of the spine are a common entity. They usually occur in older people with osteoporosis. This case is presented on account of its rarity. To the best of the authors' knowledge only one case of an osteoporotic pedicle fracture after Harrington Instrumentation has been described before. Case presentation We report the case of a 46-year-old Caucasian woman who underwent surgery due to idiopathic scoliosis with a Harrington Instrumentation (T4 to L3) 30 years ago. During the operation she was infected with hepatitis C while receiving erythrocyte concentrates and has suffered from liver cirrhosis since then. She presented with a sudden pain in her lower back and paraesthesia in both her legs but no other neurological symptoms. A computed tomography scan showed a bilateral pedicle fracture of L3 and an additional compression fracture of L4. In the first session we performed a dorsal stabilization with massive intraoperative bleeding and a postoperative failure of liver synthesis. In a second session an additional ventral augmentation was done. After the second operation she developed a hepatorenal syndrome. Both operations left the patient in a very critical state which led to a prolonged stay in the intensive care and rehabilitation unit. At her 12-month follow-up visit, she was free of complaints. Conclusion The un-physiological load of the spine after Harrington Instrumentation can lead to osteoporosis due to inactivity even in younger patients. Although these implants are not used anymore one should keep this possibility in mind when dealing with patients who have received Harrington rods in surgical procedures.

Abstract
STUDY DESIGN The previous Scoliosis Research Society brace study (JBJS-A, 1995) included patients with adolescent idiopathic scoliosis (AIS) with moderate curve sizes (25 degrees -35 degrees). The Swedish patients in this study were examined in a long-term follow-up. OBJECTIVE The aim was to analyze and compare quality of life in adulthood between AIS patients who were only observed or treated with a brace during adolescence. SUMMARY OF BACKGROUND DATA Quality of life as measured by the SRS-22 has not previously been presented for adult untreated AIS patients. METHODS Forty patients who were only observed (due to a curve increase of less than 6 degrees until maturity), and 37 brace-treated patients attended the complete follow-up, including clinical and radiologic examination, and answered 2 quality of life questionnaires (SRS-22 and Short Form-36 [SF-36]). RESULTS No differences were found between the groups in terms of age at follow-up (mean: 32 years), follow-up time after maturity (mean: 16.0 years), and curve size at inclusion (mean: 30 degrees) or at follow-up (mean: 35 degrees). The SRS-22/total score was a mean of 4.2 for braced patients and 4.1 for only observed patients. Neither total scores/subscales of the SRS-22 or SF-36 differed significantly between the groups. For the SF-36, no differences in relation to the Swedish age-matched norm scales were found for either group. CONCLUSION Patients with moderate AIS report good quality of life in their 30s, as measured by both the SRS-22 and SF-36, regardless of whether they received no active treatment or were brace treated during adolescence. Neither of the groups displayed any difference compared with the age-matched norm groups for the SF-36.

Abstract
STUDY DESIGN A retrospective study. OBJECTIVE To evaluate the long-term quality of life (QOL) of patients treated surgically for scoliosis. SUMMARY OF BACKGROUND DATA Measures of long-term outcome after surgery for scoliosis have focused mainly on radiologic changes. However, QOL issues such as working status and marital status are the subjects of greatest concern for patients who will undergo surgical treatment for scoliosis. METHODS Thirty-two patients treated surgically for scoliosis between 1976 and 1989 were included in this study. The mean duration of follow-up was 21.1 years. Eighteen patients had adolescent idiopathic scoliosis, 8 congenital scoliosis, and 6 symptomatic scoliosis. We evaluated long-term outcome by direct interview with patients. Working status, marital status, and childbearing were determined in addition to clinical and radiologic evaluation. Patients were also asked to fill out the short form (SF)-36 and Scoliosis Research Society (SRS)-22 questionnaires. RESULTS Twenty-seven patients (84.4%) were or had been engaged in various occupations without marked difficulty. Although none of the male patients was married, 62.5% of the female patients were married. Half of the female patients had delivered babies after surgery, and the mean number of such children was 1.83. On the SF-36, none of the scores for subjects with idiopathic or congenital scoliosis were markedly different from those for age-matched healthy controls. Multivariate logistic regression analysis revealed that marked preoperative Cobb angle and positive sagittal balance at the most recent follow-up were significantly associated with increased odds ratio for poor scores on the SRS-22. CONCLUSION We evaluated long-term QOL in patients treated surgically for scoliosis, and found that it was not impaired, particularly in the case of patients with idiopathic or congenital scoliosis. Larger preoperative Cobb angle and positive sagittal balance at the most recent follow-up were related to poor outcome in QOL as assessed by the SRS-22.

Abstract
STUDY DESIGN A retrospective study. OBJECTIVE To evaluate long-term outcome regarding low back pain (LBP) in patients treated surgically for scoliosis. SUMMARY OF BACKGROUND DATA Measures of long-term outcome after surgery for scoliosis have focused mainly on radiologic changes. However, subjective symptoms such as LBP after surgical treatment are of great concern to patients who undergo surgical treatment for scoliosis. METHODS Thirty-two patients treated surgically for scoliosis between 1976 and 1989 were included in this study. The mean duration of follow-up was 21.1 years. Eighteen patients had adolescent idiopathic scoliosis, 8 had congenital scoliosis, and 6 had symptomatic scoliosis. We evaluated long-term outcome by direct interview. Degree of LBP was evaluated by visual analogue scale score and Moskowitz classification in addition to clinical and radiologic evaluation. Patients were also asked to complete the SF-36 questionnaire. RESULTS Mean visual analogue scale score at the latest follow-up was 21 (0-80), and 15% of patients had occasional or frequent LBP in Moskowitz classification. On the SF-36, score for bodily pain was not markedly different from that for age-matched controls. Among radiologic findings, level of distal fusion had no effect on the incidence or severity of LBP. Furthermore, preoperative Cobb angle, latest Cobb angle, and degenerative changes of subjacent segment each exhibited no correlation with degree of LBP, either. On the other hand, sagittal balance was a factor affecting LBP following scoliosis surgery. CONCLUSION We evaluated long-term outcomes regarding LBP following scoliosis surgery. Regardless of residual back deformity, LBP was found to be no more frequent than in the normal population in Japan. Positive sagittal balance at the latest follow-up was a factor significantly contributing to LBP following scoliosis surgery.

Abstract
PURPOSE Historically, the treatment options for AIS, the most common form of scoliosis are: Exercises, in-patient rehabilitation, braces and surgery. While there is evidence in the form of prospective controlled studies that Scoliosis Intensive Rehabilitation (SIR) and braces can alter the natural history of the condition, there is no review on prospective controlled trials for surgical treatment. The aim of this review was to perform a systematic search of the Pub Med literature to reveal the evidence on scoliosis surgery. METHODS A systematic review has been performed using the Pub Med database. Literature has been searched for the outcome parameter; 'rate of progression' and only prospective controlled studies that have considered the treatment versus the natural history have been included. RESULTS No controlled study, not in the short, mid or long term, searched within the review, has been found to reveal evidence to support the hypothesis that the effects of surgery as a treatment option for AIS is superior to natural history. CONCLUSIONS No evidence has been found in terms of prospective controlled studies to support surgical intervention from the medical point of view. In the light of the unknown long-term effects of surgery and in concluding on the lack of evidence already found that surgery might change the signs and symptoms of scoliosis, a randomized controlled trial (RCT) is long overdue. Until such a time that such evidence exists, there can be no medical indication for surgery. The indications for surgery are limited for cosmetic reasons in severe cases and only if the patient and the family agree with this.

Abstract
PURPOSE To evaluate the hypothesis that spinal fusion surgery is an effective method to address spinal deformity-associated clinical problems, including magnitude of curvature (Cobb angle), pulmonary dysfunction, and pain. METHOD A systematic review was carried out using Science Citation Index (SCI) Expanded (1900 - present), Social Sciences Citation Index (1956 - present), Arts and Humanities Citation Index (1965 - present), Medline (1950 - present) and PubMed Central databases (1887 - present) to access information regarding efficacy of spine surgery in preventing or improving the health and function of patients diagnosed with scoliosis in adolescence. RESULTS Since 1950, more than 12,600 articles on scoliosis have been published, and nearly 50% (5721) focus on methods, rationale, outcome, and complications of surgical intervention. Among these, 82 articles have documented outcome for groups of > or =10 patients, treated for adolescent idiopathic scoliosis, and followed for at least 2 years after treatment. These data provide an overview of the impact of spine surgery on scoliosis for 5780 patients as surgery methods and approaches have evolved. CONCLUSIONS For most patients, a reduced magnitude of spinal curvature can be achieved through one or more spinal fusion surgeries. There is no evidence to support the premise that this result is correlated with improved pulmonary function or reduced pain.

Abstract
STUDY DESIGN Retrospective case control study. OBJECTIVE To evaluate the use of the Lenke and King classification systems in the surgical treatment of main thoracic adolescent idiopathic scoliosis (AIS), with a specific focus on radiographic and patient reported outcomes. SUMMARY OF BACKGROUND DATA There is considerable debate as to whether King or Lenke classification best fulfills the criteria for a useful classification to determine distal fusion level, i.e., is mentally descriptive of the curve being treated, uses reproducible information to provide guidance in determining distal fusion level, is prognostic of patient reported and radiographic outcomes, and has good user reproducibility. METHODS Patients operated for AIS between 1986 and 2002 with posterior spinal fusion and dual rod posterior instrumentation were retrospectively classified according to the Lenke and King classification systems. Only patients with Lenke type I curves and minimum 2-year follow-up were included. Preoperative and most recent postoperative radiographs were reviewed. The Lenke and King recommended distal fusion levels were calculated for each patient according to criteria obtained from the literature, and were compared to our actual fusion level. Patients were divided into groups based on our actual distal fusion level (i.e., longer, shorter, or in agreement with Lenke and King). The radiographic parameters and SRS 24 outcomes of patients within each group were compared. RESULTS Seventy-five patients with Lenke type 1 AIS were included in the study. The distribution of King curve types were: 31 King II curves, 34 King III curves, 9 King IV curves, and 1 double major curve. Our actual distal fusion level was in agreement with the calculated Lenke recommendation in 49% and the King recommendation in 51% of the cases. Difficulties in using the Lenke classification system were identified in up to 59% of the study patients. There were no statistically significant objectives or patient reported (SRS) differences between the groups fused in agreement, longer, or shorter than the calculated Lenke or King recommendations. CONCLUSION At intermediate follow-up, there does not seem to be significant radiographic or patient reported differences whether fusion levels are in agreement, longer, or shorter than those recommended by the Lenke or King classification systems.

Abstract
STUDY DESIGN : Literature review. OBJECTIVE : To identify scientifically sound studies that have reported changes in quality of life (QOL) after spinal deformity correction in patients with adolescent idiopathic scoliosis (AIS) and to discuss these findings. SUMMARY OF BACKGROUND DATA : Few studies have been published. Most are retrospective cohort studies and lack both preoperative and postoperative data for the outcome in terms of QOL. METHODS : A review of existing literature with the emphasis on spinal fusion for AIS and outcome as measured by health-related QOL was performed. RESULTS : Thirteen studies of various quality were found after reviewing the papers. Only 3 of them contained both preoperative and postoperative data on QOL, using the SRS-22/-24. They all reported a statistically significant improvement in some of the domain scores. The clinical implications of these findings are unclear, as the minimal clinically important differences for SRS-22/-24 have not yet been established. CONCLUSION : Weak evidence (Level IV) exists in the literature that spinal deformity correction for AIS does not significantly impact QOL in short-term or mid-term. The interpretation of this must be that there were no serious adverse events after surgery.

Abstract
Adolescent idiopathic scoliosis is a lifetime, probably systemic condition of unknown cause, resulting in a spinal curve or curves of ten degrees or more in about 2.5% of most populations. However, in only about 0.25% does the curve progress to the point that treatment is warranted. Untreated, adolescent idiopathic scoliosis does not increase mortality rate, even though on rare occasions it can progress to the >100° range and cause premature death. The rate of shortness of breath is not increased, although patients with 50° curves at maturity or 80° curves during adulthood are at increased risk of developing shortness of breath. Compared to non-scoliotic controls, most patients with untreated adolescent idiopathic scoliosis function at or near normal levels. They do have increased pain prevalence and may or may not have increased pain severity. Self-image is often decreased. Mental health is usually not affected. Social function, including marriage and childbearing may be affected, but only at the threshold of relatively larger curves. Non-operative treatment consists of bracing for curves of 25° to 35° or 40° in patients with one to two years or more of growth remaining. Curve progression of ≥ 6° is 20 to 40% more likely with observation than with bracing. Operative treatment consists of instrumentation and arthrodesis to realign and stabilize the most affected portion of the spine. Lasting curve improvement of approximately 40% is usually achieved. In the most completely studied series to date, at 20 to 28 years follow-up both braced and operated patients had similar, significant, and clinically meaningful reduced function and increased pain compared to non-scoliotic controls. However, their function and pain scores were much closer to normal than patient groups with other, more serious conditions. Risks associated with treatment include temporary decrease in self-image in braced patients. Operated patients face the usual risks of major surgery, a 6 to 29% chance of requiring re-operation, and the remote possibility of developing a pain management problem. Knowledge of adolescent idiopathic scoliosis natural history and long-term treatment effects is and will always remain somewhat incomplete. However, enough is know to provide patients and parents the information needed to make informed decisions about management options.
