Fracture of the Femoral Head

Fracture of the femoral head is a severe, relatively uncommon injury; typically, it occurs following traumatic posterior dislocation of the hip joint. The Pipkin classification is the most commonly used classification system. Diagnosis is aided by a complete history, physical examination, and imaging, including computed tomography. Treatment consists of urgent closed reduction of the dislocated hip followed by nonsurgical or surgical management of any associated fractures. Controversies include the preferred surgical approach (anterior versus posterior) and whether to perform femoral head fragment excision or internal fixation. Complications associated with fracture of the femoral head and subsequent treatment include osteonecrosis, posttraumatic osteoarthritis, and heterotopic ossification. Fracture of the femoral head has been associated with a relatively poor functional outcome.
