Spinal deformity is a common musculoskeletal problem for individuals with cerebral palsy. Severe scoliosis may impair physical function and may be a source of pain. Spine braces and carefully constructed seating arrangements may moderate the behavior of these deformities but do not seem capable of stopping progression, which often continues in adulthood. Spine fusion surgery can produce a stable, durable trunk shape that improves sitting and positioning but the process of surgery is arduous and outcomes can be compromised by numerous serious complications. Despite complications, many families and caregivers express satisfaction with the results of surgery. Careful patient evaluation, studious attention to surgical planning and performance, and a good relationship with patients, family members, and other providers is essential.
