Abstract

Spontaneous arthrodesis occurred after bilateral, extraarticular shelf augmentation and femoral varus osteotomies in a child with dislocated hips secondary to muscle imbalance from cerebral palsy. The proposed cause is heterotopic bone formation in the hip abductors in the face of insufficient range of motion exercise.
