Abstract
BACKGROUND:
: Part-time or night-time bracing has been introduced to address the poor compliance and psychological burden of full-time bracing. The results of various bracing methods vary, however, due to a lack of consistent inclusion criteria and definitions of brace effectiveness. We have evaluated the effectiveness of the Charleston night-time bending brace in the treatment of adolescent idiopathic scoliosis based on the new standardized criteria proposed by the Scoliosis Research Society.
METHODS:
: To be included in this study, patients met the following criteria proposed by the Scoliosis Research Society: diagnosis of adolescent idiopathic scoliosis, age 10 years and older when the orthosis was prescribed, Risser 0-2, a primary curve magnitude of 25 to 40 degrees, and no prior treatment. A total of 95 patients (87 girls, 8 boys) were included.
RESULTS:
: At skeletal maturity, 80 patients (84.2%) had 5 degrees or less curve progression and 15 (15.8%) had 6 degrees or more progression. Seven patients (7.8%) were recommended to undergo or underwent surgery before skeletal maturity. Eleven patients (12.6%) progressed beyond 45 degrees. According to these 3 criteria, the Charleston night-time brace was successful in 74 patients (77.9%). Depending on curve type, we observed success rates of 78.3% (47/60) for double, 71.4% (15/21) for thoracic, 83.3% (5/6) for thoracolumbar, and 87.5% (7/8) for lumbar curves. Success rates of 80.0% (36/45) and 76.0% (38/50) were observed in patients with curve magnitudes at bracing of 25 to 30 degrees and 31 to 40 degrees, respectively. Patients with high apex curves had a 67.6% (23/34) success rate, and those with low apex curves had 83.0% (39/47) success rate. Brace success rates among patients with initial Risser signs of 0, 1, and 2 were 68.8% (22/32), 80.6% (25/31), and 84.4% (27/32), respectively.
CONCLUSIONS:
Compared with the results of previous natural history and conventional brace study, the Charleston night-time bending brace is effective for the treatment of adolescent idiopathic scoliosis.
