This 2002 narrative review by Flynn and Miller covers the full spectrum of hip disorders in cerebral palsy — from early dysplasia through painful dislocation — synthesizing the natural history, radiographic evaluation, and a staged surgical decision framework based on patient age and migration index.
When you see a nonambulatory child with cerebral palsy, don't rely on exam — get an AP pelvis and measure the migration index: intervene with soft-tissue lengthening once MI exceeds 25%, and proceed to one-stage comprehensive reconstruction if MI exceeds 60% in a child ≥4 years old before degenerative changes foreclose that option.
