Aims

To systematically evaluate whether bracing can effectively achieve curve regression in patients with adolescent idiopathic scoliosis (AIS), and to identify any predictors of curve regression after bracing.

Methods

Two independent reviewers performed a comprehensive literature search in PubMed, Ovid, Web of Science, Scopus, and Cochrane Library to obtain all published information about the effectiveness of bracing in achieving curve regression in AIS patients. Search terms included “brace treatment” or “bracing,” “idiopathic scoliosis,” and “curve regression” or “curve reduction.” Inclusion criteria were studies recruiting patients with AIS undergoing brace treatment and one of the study outcomes must be curve regression or reduction, defined as > 5° reduction in coronal Cobb angle of a major curve upon bracing completion. Exclusion criteria were studies including non-AIS patients, studies not reporting p-value or confidence interval, animal studies, case reports, case series, and systematic reviews. The GRADE approach to assessing quality of evidence was used to evaluate each publication.

We set out to determine the impact of surgery on quality of life and function in patients who had undergone surgery for symptomatic peri-acetabular metastases. From a prospective database we retrospectively reviewed 46 consecutive patients who had been treated operatively between June 2003 and June 2009. The mean age of the patients was 56.4 years (20 to 73) and the mean post-operative follow-up was 19.2 months (4 to 70). Functional evaluation and quality-of-life assessments were performed. At the most recent follow-up, 26 patients (56.5%) were alive. Their median survival time was 25.0 months. Ten major postoperative complications had occurred in eight patients (17.4%). The mean post-operative Musculoskeletal Tumor Society score (MSTS 93) was 56.3% (6.7% to 90.0%). Improvement in the Eastern Cooperative Oncology Group (ECOG) performance status was seen in 32 patients (69.6%). On the European Organisation for Research and Treatment of Cancer core quality-of-life questionnaire (QLQ-C30) measure of global health status there was a statistically significant improvement from the patients’ pre-operative status (42.8 (sd 13.7)) to that found at the latest follow-up (58.0 (sd 12.5)) (p = 0.001). The only statistically significant change in the nine symptom domains of the QLQ-C30 was a reduction in the mean level of pain (from 59.1 to 29.5 (out of 100)) (p < 0.001).

Surgery for patients with peri-acetabular metastases reduces pain and improves their quality of life, and has a low rate of surgical complications.

The results of 10 patients with severe rigid drop-foot corrected by the Lambrinudi triple arthrodesis were studied. The average amount of correction was 47 degrees, as evaluated from standing radiographs taken before and after operation. Radiological features of osteoarthritis and of flattening of the talus were common, but the feet were painless when reviewed at an average of 70 months later. A satisfactory range of movement was obtained at the ankle joint.

Twenty-eight patients with adolescent idiopathic scoliosis treated by anterior spinal fusion with Dwyer instrumentation were reviewed. The average length of follow-up was 6.9 years. This technique produced better correction of lateral curvature and rotation than Harrington instrumentation, particularly in the thoracolumbar and lumbar region. The length of spine requiring fusion was also shorter. There is, however, a tendency for Dwyer instrumentation to lead to kyphosis. Morbidity was significant and included one case of paraplegia, four cases of deep infection and one case of instrument failure. All of these complications, except one case of deep infection, occurred in patients with curves with an apex above the seventh thoracic vertebra.
