Problem: Hip instability in cerebral palsy is very common problem and occurs because of muscular imbalance. It includes hip subluxation / dislocation, acetabular dysplasia with or without joint degeneration & femoral head deformity. Incidence of Hip dysplasia is high in quadriplegic & non ambulatory children. So it is very important to have high suspicion of hip dislocation in these children and can be identified at very early stage
Management Protocol:Spasticity of adductor longus is the primary cause of hip dysplasia. We can reduce chances of hip instability by doing adductor tenotomy. Patient with acetabular dysplasia need acetabular reorientation osteotomy. Hip dislocation need open reduction along with corrective osteotomy of femur & acetabulam. Correction of all contracture & deformity also needs to be done during this surgery (SEMLS).
