Abstract: Objective To assess the sensitivity of indices of hip development in children with spastic diple-gia resulting from cerebral palsy. Methods X-ray images of the hips of 57 children with cerebral palsy ( the cere-bral palsy group) were checked, and the acetabular index ( AI), femur head migration percentage ( MP), center-edge angle and neck-shaft angle (NSA) were compared with those of normal children ( the control group, n = 30).Results The differences in MP and NSA between the two groups were significant. The prevalence of hip subluxation was 20.45% among the children with spastic diplegia who could not walk independently, and the prevalence was sig-nificantly greater in children 3 to 5 years old than among those under 3. Conclusion The MP can be used as a sen-sitive index to evaluate hip development. Age is a relevant factor affecting the hip development of children with cere-bral palsy.
