Abstract

Study Design. Multicenter, prospective clinical series. Objective. To investigate the effect of preoperative bracing on postoperative outcome of posterior spine fusion with instrumentation for adolescent idiopathic scoliosis. Summary of Background Data. Bracing is the standard of care for adolescent idiopathic scoliosis between 25° and 45°, yet the efficacy of bracing is questionable. It is important to evaluate the effect of bracing on outcomes in the adolescent idiopathic scoliosis population. Methods. We reviewed the outcomes of 281 before surgery braced and 328 before surgery nonbraced patients who underwent posterior spine fusion with instrumentation for adolescent idiopathic scoliosis before operation and at 2 years after operation using the Scoliosis Research Society instrument (SRS-30) and the Spinal Appearance Questionnaire. Results. At 2 years after operation, nonbraced patients demonstrated a greater improvement in the SRS-30 Pain domain score (0.23 vs. 0.08, P < 0.001), more improvement in back pain at rest (26.7% vs. 20.5%, P = 0.0009), and more improvement in back pain in the past 6 months (42.4% vs. 32.6%, P = 0.039) compared to braced patients. Also at 2 years after operation, nonbraced patients reported higher SRS-30 Activity domain scores (4.38 vs. 4.32, P = 0.031), Satisfaction domain scores (4.53 vs. 4.42, P = 0.007), and Total scores (4.27 vs. 4.35, P = 0.036) compared with braced patients. The 2-year Spinal Appearance Questionnaire scores showed that nonbraced patients reported a greater "decrease in importance" than braced patients in having "more even shoulders" (79.4% vs. 70.5%, P = 0.03), "more even hips" (74.6% vs. 71.6%, P = 0.042), and "more even ribs in back" (78.4% vs. 69.5%, P = 0.05). Conclusion. Before surgery braced patients have more pain, lower activity levels, lower satisfaction, and lower total SRS-30 scores at 2 years after operation. Braced patients also have more "spine-specific" appearance concerns compared to nonbraced patients. These results suggest a negative impact of preoperative bracing on outcomes after posterior spinal fusion for adolescent idiopathic scoliosis. This "brace signature" should be taken into account when brace treatment is being considered.
