False aneurysm after intramedullary nailing of the femur.

False aneurysm is a rare cause of non-union of a fracture. Reports have recently been published by Bassett and Houck (1964), Dameron (1964) and Meyer and Slager (1964), in which injury to the arteria profunda femoris or its branches complicated the insertion of screws across the femoral shaft and resulted in the development of false aneurysm. The case reported here complicated intramedullary nailing of the femoral shaft.
