“…One of the most important evaluations relates to the assessment of curve flexibility [6,7,11,13]. After understanding the flexibility of curves, spine surgeons are able to reasonably judge the rigidity of scoliosis, determine fusion levels and predict correction outcome.…”

“…After understanding the flexibility of curves, spine surgeons are able to reasonably judge the rigidity of scoliosis, determine fusion levels and predict correction outcome. Several types of curve flexibility assessment methods have been introduced previously, such as measurements on supine side bending [7,26], fulcrum bending [6,15] and traction films [11,16]. Evaluating the curve flexibility through measurement on supine side bending films is currently feasible and convenient [7].…”

“…In both groups, pre-operative radiographic evaluations included standing postero-anterior (PA) and lateral radiographs, as well as supine PA and side bending (SB) radiographs [7]. Post-operative radiographic evaluations consisted of standing PA and lateral radiographs taken about 2 weeks after surgery.…”

Purpose Brace treatment has served as a vital non-surgical procedure for immature adolescent idiopathic scoliosis (AIS) patients with a mild or moderate curve. For the patients who fail in bracing and resort to surgery, it is unclear whether prior full-time brace treatment significantly influences outcomes. This study aims to investigate whether prior brace treatment has a negative impact upon the flexibility and correctability of the main curve in patients with AIS. Methods The participants were collected from female AIS patients who underwent posterior correction surgery with pedicle screw instrumentation from August 2006 to December 2010, with or without prior brace treatment. Patients included in Group A had prior brace treatment over a 1-year period, and underwent surgery within 6 months after cessation of bracing; those in Group B received no prior treatment and were randomly selected from our database. Curve flexibility pre-surgery and curve correctability post-surgery were computed and compared between both groups and subgroups according to the curve location.Results Each group consisted of 35 patients. Age, curve magnitude and location were comparable between the two groups. Before surgery, patients in Group A had a slightly lower curve flexibility than those in Group B (52 vs. 60 %, P = 0.036). After surgery, satisfactory correction results were observed in both groups, but the average post-operative main curve magnitude of patients in Group B was 4°l ess than that of Group A (10°vs. 14°, P = 0.010). The curve correctability in Group B was significantly higher than that in Group A (80 vs. 74 %, P = 0.002). No matter what curve pattern the patient had, having a prior history of brace treatment resulted in a trend of lower flexibility and correctability of their scoliosis. Conclusions Good surgical correction can be achieved in AIS patients who have been unsuccessful with prior brace treatment. However, a history of prior brace treatment leads to a trend of lowering the curve flexibility, and in turn, negatively impacts upon the curve correctability.

ContextPrevious long-term studies of idiopathic scoliosis have included patients with other etiologies, leading to the erroneous conclusion that all types of idiopathic scoliosis inevitably end in disability. Late-onset idiopathic scoliosis (LIS) is a distinct entity with a unique natural history.Objective To present the outcomes related to health and function in untreated patients with LIS. Design, Setting, and PatientsProspective natural history study performed at a midwestern university with outpatient evaluation of patients who presented between 1932 and 1948. At 50-year follow-up, which began in 1992, 117 untreated patients were compared with 62 age-and sex-matched volunteers. The patients' mean age was 66 years (range, 54-80 years).Main Outcome Measures Mortality, back pain, pulmonary symptoms, general function, depression, and body image. ResultsThe estimated probability of survival was approximately 0.55 (95% confidence interval [CI], 0.47-0.63) compared with 0.57 expected for the general population. There was no significant difference in the demographic characteristics of the 2 groups. Twenty-two (22%) of 98 patients complained of shortness of breath during everyday activities compared with 8 (15%) of 53 controls. An increased risk of shortness of breath was also associated with the combination of a Cobb angle greater than 80°and a thoracic apex (adjusted odds ratio, 9.75; 95% CI, 1.15-82.98). Sixty-six (61%) of 109 patients reported chronic back pain compared with 22 (35%) of 62 controls (P = .003). However, of those with pain, 48 (68%) of 71 patients and 12 (71%) of 17 controls reported only little or moderate back pain.Conclusions Untreated adults with LIS are productive and functional at a high level at 50-year follow-up. Untreated LIS causes little physical impairment other than back pain and cosmetic concerns.
