Abstract:
OBJECTIVE: To find the incidence of hip subluxation according to corrected chronologic age (CCA), neuromotor type, severity and motor quotient in cerebral palsy (CP). METHOD: We reviewed clinical records and radiological findings of CP visited our hospital between June 1999 and June 2003. One hundred ninety-six children with CP (mean CCA: 19.0+/-13.9 months) were evaluated by measurement of the migration index, acetabular index, central edge angle and neck shaft angle from pelvic X-ray. The hip subluxation was defined as above 33% on the migration index. RESULTS: Among the 311 hips, 35 hips (11.3%) were subluxated and none was dislocated. The incidence of hip subluxation in CP was not significantly different in neuromotor type, severity, type by involvement of extremity and motor quotient, but statistically different in 25~36 month old group in comparison with the other age groups (p<0.05). CONCLUSION: The hip subluxation in CP may occur irrespective of neuromotor type, severity, type by involvement of extremities and motor quotient. Therefore, it is recommended to perform routine screening and follow-up examination of pelvic x-ray in CP to find out hip subluxation.
