A Case of Perthes Disease in Cerebral Palsy Patient

Perthes disease is a disorder of femoral head that affects 5–10 per 100,000 children. There is a transient disruption of the blood supply to the femoral head followed by collapse and subsequent remodeling. The majority of cases present between the ages of 4 years and 10 years. We are reporting the unusual case of a child with cerebral palsy who developed a left-sided limping gait. In cerebral palsy patients, spasticity can result in femoral head and acetabular deformities which leads to limping. The possibility of Perthes disease in such patients cannot be ignored. So, another radiological investigation can help to reach an appropriate diagnosis as was considered in our patient.
