The Pediatric Spine Registry (PS Registry) is operated by the Pediatric Spine Foundation (PSF) and collects patient data on children with spine and chest wall disorders. Any type of spine and chest wall disorder as determined by the investigator may be entered. The most common type of spine deformity in children is scoliosis. Scoliosis takes many forms and often can be associated with other congenital disorders. With the large number of disorders and types of scoliosis along with other spine and chest wall deformities, a single institution often does not have a large enough patient population to provide meaningful research results.
