The patient sustained a displaced femoral neck fracture, which was evident on the radiographs. Femoral neck fracture is one of the most common fractures in the elderly population. The injury can cause significant disability and death, with a same-year mortality rate of 25%. Displaced femoral neck fractures disrupt the hip capsule and blood supply to the femoral head.

Treating the fracture with closed reduction and cannulated screw fixation would not restore blood supply to the femoral head, and osteonecrosis would occur. Therefore, the treatment of choice for displaced femoral neck fracture in this age group is head replacement or hemiarthroplasty.

Total hip arthroplasty is generally reserved for younger more active patients and for those with preexisting arthritis who sustain a displaced femoral neck fracture. Total hip arthroplasty offers better pain relief and functional outcome in this population than hemiarthroplasty. Cannulated hip screw fixation is recommended for nondisplaced femoral neck fractures, as the hip capsule and femoral head blood supply remain intact and healing is likely. Intramedullary nail fixation is indicated for intertrochanteric hip fractures.1,2
