Pseudoaneurysm of the femoral artery complicating internal fixation of the trochanteric fracture of the femur results mainly from a penetrating injury by the drill bit or screw and involves particularly the profunda femoris artery. Recently, we experienced a case of pseudoaneurysm of the superficial femoral artery following insertion of the Gamma nail for trochanteric fracture of the femur and scrutinized the causes of this injury. The superficial femoral artery lies in close proximity to the femur by adduction of the involved limb against the perineal post on the fracture table during Gamma nailing.
