Results from this study indicated use of a dynamic brace that incorporates thoracic corrective elastic bands was not as effective as a commonly used thoracolumbosacral orthosis for the prevention of curve progression in patients with adolescent idiopathic scoliosis.
Researchers retrospectively compared 97 patients with adolescent idiopathic scoliosis (AIS) treated with the dynamic SpineCor (The Spine Corporation Limited) brace to a group of 146 patients treated with the Boston brace (Boston Brace). Investigators evaluated patient age, Risser sign at the onset of treatment, initial main Cobb angle and curve type.
Results showed, on average, progression in the dynamic brace group and the rigid brace group was 14.7° and 9.6°, respectively. Investigators noted the average Cobb angle at the end of the study was 46.9° in patients treated with dynamic brace and was 41.7° in those treated with rigid brace. Progression of at least 6° was found in 76% of patients in the dynamic brace group compared with 55% of patients in the rigid brace group.
According to researchers, 51% of patients in the dynamic brace group and 37% of patients in the rigid brace group reached 45°. Investigators found 39% of patients treated with the dynamic brace and 30% of patients treated with the rigid brace were referred to surgery. Patients treated with the dynamic brace had a 2.67-times greater chance of their curves progressing at least 6° and had a 2.07-times greater chance of reaching at least 45°. ‒ by Monica Jaramillo
