Abstract

The invention describes a surgical implant for providing stabilization of an intraosseous circumferential fracture within a femoral neck of a proximal femur. The surgical implant includes a bone barrel and a cortical side plate having at least one screw hole to allow rigid fixation of the implant to the proximal femur. The cortical side plate abuts a lateral cortex of the proximal femur having a lateral portal of entry to ensure the bone barrel remains substantially parallel to an inner bony surface of the lateral portal of entry at all times. The bone barrel ensures a collection of bone growth elements is retained intraosseously. An osteomedullary rod being coaxially aligned with the bone barrel includes an axial threading for securely engaging an internal mating thread of the bone barrel. The axial threading is adapted to allow clockwise axial rotation of the osteomedullary rod to position a compression head thereof in operational contact with an autogenous cancellous osteomedullary bone cylinder. Further axial clockwise rotation induces the collection of bone growth elements to be extravasated from the autogenous cancellous osteomedullary bone cylinder and to flow into a region of surrounding bone within the femoral head and the femoral neck so as to induce bidirectional new bone formation. Other embodiments of the invention are described herein.
