Abstract

BACKGROUND: Conventional surgical treatment for adolescent idiopathic scoliosis (AIS) consists of correction of the spinal deformity with rigid spinal instrumentation and fusion. Less-invasive and fusionless surgery could potentially improve patient outcomes. The purpose of the present study was to evaluate the efficacy of a recently U.S. Food and Drug Administration (FDA)-approved posterior peri-apical self-distracting device (ApiFix) that is designed to gradually correct the deformity without spinal fusion. METHODS: In a prospective cohort study of 20 patients with AIS (Risser stage 1-4; Lenke 1 or 5; major curve Cobb angle, 40° to 55°; and Bunnell scoliometer rotation,
