The supracondylar fracture of the femur is very difficult to treat regardless of whether non-surgical of surgical methods are selected. Recent advance of device for internal fixation such as AO angle plate and Judet plate improved the result of the operative treatment. But the operative technizue is difficult and in elderly patient rigid fixation can not be obtained due to osteoporsis and comminution of the fracture. So intramedullary nailing such as Zickel supracondylar element were treated with the Ender anil with distal screw in Red Cross Hospital from September 1987 to December 1988.
