312. Residual lumbar hyperlordosis is associated with worsened hip status 5 years after cerebral palsy scoliosis correction

Abstract

BACKGROUND CONTEXT Cerebral palsy (CP) can be described as a “static encephalopathy with progressive musculoskeletal pathology.” Nonambulant children (GMFCS IV&V) have high rates of both spastic hip disease and neuromuscular scoliosis. Adult sagittal spinal deformity correction is known to cause acetabular retroversion and reduced pelvic tilt, resulting in increased rates of prosthetic hip dislocation; however, the role of spinal alignment on hip status in CP remains unknown. PURPOSE To identify surgical factors and postoperative spinal alignment parameters that are associated with worsening postoperative hip status (WHS) (ie, subluxation, dislocation or resection) after spinal fusion.
