Femoral neck fracture in an arthrodesed hip treated by a supracondylar intramedullary locked nail

We describe a case of a femoral neck fracture occurring 51 years after a hip arthrodesis. This rare lesion in an obese woman was treated with a straight supracondylar nail with proximal and distal locking inserted retrograde from the subtrochanteric area into the ileum. Full weight bearing was achieved within 1 week postoperatively, and union was present 3 months following the operation.
