This invention relates to a surgical intramedullary mail (10), for stabilisation of condylar and supracondylar fractures of the femur. It incorporates a Cruciate arrangement of two obliquely crossing locking bolts (21 and 26) such that each condyle of the femur is gripped by an individual bolt. By this means both femoral condyles are stabilised with respect to the shaft of the femur. The bolts are oriented so that each passes through the main extra-articular mass of each condyle, Further predrilled holes are provided (30, 35) for insertion of proximal locking bolts to stabilise the nail with respect to the shaft of the femur. The nail is intended for retrograde insertion from distal to proximal into the intramedullary canal of the femur. Insertion of the locking bolts may be facilitated by the use of a temporary jig which is attached securely to the distal end of the nail (11). Nails of similar design can be used for stabilisation of equivalent fractures of the humerus.
