Femoral head fractures combined with hip dislocation are very rare injuries. In most cases, they result from high-energy trauma to the hip or lower extremity during traffic accidents. Various therapy options have been suggested to treat these injuries. Especially, different joint-preserving surgical options have been described for the treatment of traumatic osteochondral injury of the femoral head in young, active patients. In this report, we present a case that a traumatic osteochondral lesion to the femoral head after hip dislocation was treated with osteochondral autografts (OATS) from the non-weight-bearing area of the ipsilateral inferior femoral head through a surgical hip dislocation. After 1 year, the clinical and radiological outcome was satisfactory with no evidence of posttraumatic osteoarthritis and no pain of patients.

(A) An intraoperative image of the femoral head after a surgical hip dislocation. (B) An intraoperative image showing placement of Acutrak (Acuemd) for fixation of the main fragment after anatomical reduction. A large osteochondral defect in the weight-bearing surface of the femoral head is visible.
