Introduction: The incidence of hip abnormalities in cerebral palsy (CP) patients has been reported as low as 2.6% and as high as 28%. Hip displacement is the second most common deformity after equines. The objective of this study is to evaluate the radiological changes of hip in CP for detecting early features of hip instability.

Materials and methods: A total of 91 hips of 52 patients with CP who attended for rehabilitation management were randomly selected for the study. Hip surveillance was done in those cases where the clinical evaluation alone could not access stability. All the selected cases were evaluated radiologically with respect to acetabular angle, neck-shaft angles, degree of subluxation (migration percentage) and shape of femoral head.

Results: 38 hips showed grade I, 14 hips grade II, 6 hips grade III, and 2 hips grade IV stage of migration percentage. Flattening of femoral head was laterally seen in 16 cases, both medial and lateral flattening was seen in 8 cases of subluxated hip. Acetabular roof angle was increased in cases with grade III and IV migration percentage. Acetabular angle was within 12 to 75° with mean angle of 32°. The mean true neck-shaft angle was 145.5° ranging from 134° to 170°

Conclusion: Early detection of hip instability in Cerebral Palsy helps in timely intervention and that reduces or delays need for reconstructive surgery.
