Description
Summary:Abstract Introduction The objective of the present study was to assess, at skeletal maturity, the efficacy of non-operative treatment by isolated nighttime brace in the prevention of progression of progressive idiopathic scoliosis of less than 25°. Hypothesis Isolated nighttime brace treatment is effective in the prevention of progression of mild progressive idiopathic scoliosis (Cobb < 25°). Material and methods A single-center retrospective study included 142 patients managed by nighttime brace for progressive idiopathic scoliosis with Cobb angle < 25°, with assessment at skeletal maturity. Mean Cobb angle at start of treatment was 15.5° (range, 10–25°). Mean values for Cobb angle and sagittal parameters before treatment and at skeletal maturity were compared on Student t -test. Change in Cobb angle over time was also analyzed. Results Mean Cobb angle at skeletal maturity was 16.3°, showing significant increase over baseline (15.5°; P = 0.04), although the difference was less than the uncertainty of measurement (± 6°). In baseline Risser 0 or 1, mean change in Cobb angle at skeletal maturity (16.2°) was not significant ( P = 0.1). Cobb angle diminished in 26 cases (18%), increased in 24 (17%) and was unchanged in 92 (65%). Conclusion The present study confirmed the efficacy of non-operative treatment by nighttime brace in mild progressive idiopathic scoliosis (< 25°) in a large majority of cases. A nighttime brace thus seems to be an effective option for the treatment of adolescent scoliosis, ensuring a safe curve of around 20°. Level of evidence Level IV, retrospective study.
