摘      要：Avascular necrosis of the femoral head is a known complication of femoral neck fracture but on the contrary, femoral neck fracture in a case of preexisting avascular necrosis is a very rare phenomenon. We present a case study of a 47 year old Iraqi male who developed sponaneous ipsilateral subcapital femoral neck fracture under the condition of preexisting sickle cell disease and avascular necrosis of the femoral head. The fracture was unnoticed for a few months. The patient was managed successfully byuncemented total hip arthroplasty. Postoperative recovery was uneventful and he was discharged 4 days after surgery. At 1 year＇s follow-up, the patient had normal gait and hip function, with no sign of loosening or any other complications on radiograph.
