RESUMO
STUDY DESIGN: The Scoliosis Research Society (SRS) brace study (published in the JBJS-A, 1995) was comprised of patients with adolescent idiopathic scoliosis with moderate curve sizes (25°-35°). Forty observed and 37 braced patients (77% of the original group) attended a follow-up, a mean of 16 years after onset of maturity. OBJECTIVE: To analyze whether the subjectively evaluated present body appearance affects outcome as measured by quality of life in adult patients, previously treated by observation alone (nonbraced) or with a brace during adolescence. SUMMARY OF BACKGROUND DATA: Few reports exist where validated outcome measures for body appearance have been used. METHODS: Two quality-of-life questionnaires, the Scoliosis Research Society-22 (SRS-22) questionnaire and the 36-Item Short-Form Survey Instrument (SF-36), were answered. The patient's opinion on body appearance was evaluated pictorially (i.e., sketches) using the spinal appearance questionnaire, in which 7 aspects of asymmetry are graded. These scores were compared with curve sizes, scoliometer measurements for grading trunk asymmetry, and quality-of-life measures. RESULTS: At follow-up, both groups were similar in terms of age (mean = 32 years) and curve size (mean = 35°). Distortion was inversely related to SRS-22 total score and satisfaction/dissatisfaction with management subscore, but not related to the SRS-22 function subscore. No difference was found between the groups in terms of trunk rotation, where the means were 10.7° and 10.8° for the nonbraced and braced patients, respectively. The nonbraced patients estimated that their body appearance was significantly less distorted than the braced patients (mean = 12.9 and 15.0, respectively; P = 0.0028). CONCLUSION: Patients who experienced less body asymmetry were more satisfied with treatment and had a better quality of life. In spite of similar curve sizes and trunk rotation in both groups, the nonbraced patients felt that their body appearance was less distorted than that of the braced patients.

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.

STUDY DESIGN: A modified Delphi study conducted with 28 experts in back pain research from 12 countries. OBJECTIVE: To identify standardized definitions of low back pain that could be consistently used by investigators in prevalence studies to provide comparable data. SUMMARY OF BACKGROUND DATA: Differences in the definition of back pain prevalence in population studies lead to heterogeneity in study findings, and limitations or impossibilities in comparing or summarizing prevalence figures from different studies. METHODS: Back pain definitions were identified from 51 articles reporting population-based prevalence studies, and dissected into 77 items documenting 7 elements. These items were submitted to a panel of experts for rating and reduction, in 3 rounds (participation: 76%). Preliminary results were presented and discussed during the Amsterdam Forum VIII for Primary Care Research on Low Back Pain, compared with scientific evidence and confirmed and fine-tuned by the panel in a fourth round and the preparation of the current article. RESULTS: Two definitions were agreed on a minimal definition (with 1 question covering site of low back pain, symptoms observed, and time frame of the measure, and a second question on severity of low back pain) and an optimal definition that is made from the minimal definition and add-ons (covering frequency and duration of symptoms, an additional measure of severity, sciatica, and exclusions) that can be adapted to different needs. CONCLUSION: These definitions provide standards that may improve future comparisons of low back pain prevalence figures by person, place and time characteristics, and offer opportunities for statistical summaries.

STUDY DESIGN: The Swedish patients included in the previous SRS brace study were invited to take part in a long-term follow-up. OBJECTIVE: To investigate the rate of scoliosis surgery and progression of curves from baseline as well as after maturity. SUMMARY OF BACKGROUND DATA: Brace treatment was shown to be superior to electrical muscle stimulation, as well as observation alone, in the original SRS brace study. Few other studies have shown that brace treatment is effective in the treatment of scoliosis. METHODS: Of 106 patients, 41 in Malmö (all Boston brace treatment) and 65 in Göteborg (observation alone as the intention to treat), 87% attended the follow-up, including radiography and chart review. All radiographs were (re)measured for curve size (Cobb method) by an unbiased examiner. Searching in the mandatory national database for performed surgery identified patients who had undergone surgery after maturity. RESULTS: The mean follow-up time was 16 years and the mean age at follow-up was 32 years The 2 treatment groups had equal curve size at inclusion. The curve size of patients who were treated with a brace from the start was reduced by 6 degrees during treatment, but the curve size returned to the same level during the follow-up period. No patients who were primarily braced went on to undergo surgery. In patients with observation alone as the intention to treat, 20% were braced during adolescence due to progression and another 10% underwent surgery. Seventy percent were only observed and increased by 6 degrees from inclusion until now. No patients underwent surgery after maturity. Progression was related to premenarchal status. CONCLUSION: The curves of patients with adolescent idiopathic scoliosis with a moderate or smaller size at maturity did not deteriorate beyond their original curve size at the 16-year follow-up. No patients treated primarily with a brace went on to undergo surgery, whereas 6 patients (10%) in the observation group required surgery during adolescence compared with none after maturity. Curve progression was related to immaturity.

STUDY DESIGN: A consecutive series of patients with adolescent idiopathic scoliosis (AIS), treated between 1968 and 1977 before 21 years of age with either distraction and fusion using Harrington rods (ST, n = 156; 145 females and 11 males) or with brace (BT, n = 127; 122 females and 5 males), were followed at least 20 years after completion of the treatment. OBJECTIVES: To determine the long-term outcome in terms of spinal mobility and muscle strength and its possible correlations to present back pain and function in patients surgically or brace treated for AIS. SUMMARY OF BACKGROUND DATA: Few reports on long-term outcome on these variables have previously been presented for this group of patients. METHODS: A total of 135 (87%) of ST and 102 (80%) of BT patients underwent a complete examination by two unbiased observers incl. evaluation of lumbar muscle endurance and spinal mobility, curve size (Cobb method), validated questionnaires in terms of general and disease-specific quality of life aspects, as well as present back function and pain. An age- and sex-matched control group of 100 persons was randomly selected and subjected to the same examinations. RESULTS: For both ST and BT groups, lumbar spinal motion as well as muscle endurance were significantly decreased compared with controls. For ST patients, better lumbar extensor and flexor muscle endurance or lumbar spinal mobility correlated with a better physical function. The length of fusion into the lumbar spine correlated inversely with lumbar range of motion, but the finger-floor distance was not affected. BT patients with reduced lumbar spinal mobility experienced lumbar back pain more often than controls. CONCLUSIONS: For both brace treated and surgically treated AIS patients, spinal mobility and muscle endurance were reduced more than 20 years after completed treatment. The physical function was not severely restricted.

STUDY DESIGN: A consecutive series of patients with adolescent idiopathic scoliosis and brace-treated (BT) between 1968 and 1977 before age 21 years (BT: n = 127; 122 females and 5 males) were followed-up at least 20 years after completion of the treatment. OBJECTIVES: To determine the long-term outcome in terms of back pain and function in patients BT for adolescent idiopathic scoliosis. SUMMARY OF BACKGROUND DATA: Few reports on long-term outcome of back pain and function have previously been presented for consecutive groups of these patients. MATERIALS AND METHODS: One hundred ten (87%) BT patients were reexamined as part of an unbiased personal follow-up. This included a clinical examination, evaluation of curve size (Cobb method), and degenerative findings in full standing frontal and lateral radiographs. Validated questionnaires in terms of general and disease-specific quality-of-life aspects as well as present back and pain symptoms were used. One hundred nine had complete follow-up. An age- and sex-matched control group of 100 persons was randomly selected and subjected to the same examinations. RESULTS: The deterioration of the curves was a mean of 7.9 degrees for all curves, excluding the only patient who underwent operation after 4 years (increase = 27 degrees). The patients had significantly more degenerative disc changes than the controls. Lumbar and thoracic back pain, although mild (2.7 on visual analogue scale), was significantly more frequent among the patients than the controls (75 vs. 47%, P = 0.0050 and 35.8 vs. 22.0%, P = 0.033, respectively). Only 24% of the patients admitted daily pain and analgesics were sparsely used. The patients had a slightly, but significantly, worse back function as measured by the Oswestry Disability Index (9.2 vs. 4.8, P = 0.0012) and general function score (7.7 vs. 4.2, P = 0.0006), but general health-related quality of life was not affected. No differences could be seen in sociodemographic variables between the groups, except for having ever been on sick leave because of the back (38% vs. 19%, P = 0.0036). Furthermore, no differences could be found between patients with different curve types (single thoracic, n = 50; lumbar, n = 19; double curves, n = 40). No correlation could be found between pain and its localization and curve size, an increase of at least 10 degrees since end of treatment, curve type, degenerative changes on any of the two lowest lumbar disc levels, body mass index, or smoking. CONCLUSIONS: More than 20 years after brace treatment for AIS, minimal pain and no dysfunction occurred compared with normal controls. Compared with surgically treated patients with a mean end result similar to this group, no significant differences were found except that BT patients experience more affective components of their pain.

STUDY DESIGN: A consecutive series of patients with adolescent idiopathic scoliosis, treated between 1968 and 1977 before age 21 years with distraction and fusion using Harrington rods (surgically treated: n = 156; 145 females and 11 males) were followed-up at least 20 years after completion of the treatment. OBJECTIVES: To determine the long-term outcome in terms of back pain and function in patients surgically treated for adolescent idiopathic scoliosis. SUMMARY OF BACKGROUND DATA: Few reports on long-term outcome of back pain and function have previously been presented for this group of patients. Results presented are not conclusive regarding effects on back pain and its correlation to a fusion extending into the lower lumbar spine. MATERIALS AND METHODS: One hundred forty-two (91%) of the patients were reexamined as part of an unbiased personal follow-up. This included a clinical examination and evaluation of curve size (Cobb method) and degenerative findings in full standing frontal and lateral radiographs. Validated questionnaires in terms of general and disease-specific quality of life aspects as well as present back and pain symptoms were used. One hundred thirty-nine had complete follow-up. An age- and sex-matched control group of 100 individuals was randomly selected and subjected to the same examinations. RESULTS: The deterioration of the curves was 3.5 degrees for all curves and eight (5.1%) of the patients treated with fusion had undergone some additional curve-related surgical procedure. The patients had significantly more degenerative disc changes than the controls. Lumbar pain, although mild (2.4 on visual analogue scale), was significantly more frequent among the patients than the controls (65 vs. 47%, P = 0.0079). Only 25% of the patients admitted daily pain, and analgesics were sparsely used. No major differences of back function and general health-related quality of life were noted between the patients or the controls. Except for having been on sick-leave ever because of the back (45% vs. 19%, P = 0.0040) no differences could be seen in sociodemographic variables between the groups. Furthermore, no differences could be found between patients fused to L3 or higher (n = 102) versus L4 or lower (n = 37). No correlation could be found between pain and its localization and various variables on the scoliotic curve, body mass index, or smoking. Persisting discomfort and/or sensory loss were noted significantly more often among the patients who had the autologous bone harvesting performed through a separate incision over the iliac crest (24.3%) than among those in whom this was performed through an elongated midline incision (4.6%, P = 0.0015). CONCLUSIONS: Minimal pain and no dysfunction occurred (mean) 23 years after fusion for adolescent idiopathic scoliosis compared with normal straight controls. Significantly more pain in the scar region occurred when bone graft from an incision over the posterior iliac crest was used for harvesting bone to the fusion compared with an incision performed as an elongation of the midline incision used for the scoliosis surgery.
