title: Central dislocation of the hip secondary to insufficiency fracture.
abstract: We present a case report of a 45-year old man who sustained a central dislocation of the hip secondary to an insufficiency fracture of the acetabulum. At the time of presentation he was on alendronate therapy for osteoporosis which had been previously investigated. CT scanning of the pelvis was useful for pre-operative planning which confirmed collapse of the femoral head but no discontinuity of the pelvis. The femoral head was morcellized and used as bone graft for the acetabular defect and an uncemented total hip replacement was performed.
