ABSTRACT:
Apparatus and method of performing percutaneous bone surgery particularly to repair a particular fractured trochanteric portion of a femur. The technique includes the making of a small first incision to the bone, introducing a tubular guide, placing a drill in the tube activating the same, drilling a bore into the bone, withdrawing the drill and guide and inserting a new pin and pin insertion means to place the pin in position in the bore and due to its design leaving a portion extending from said bone bore to abut and lie against the femur at approximately 145.degree. to the angle of the portion of the pin in the bore. In addition the pin insertion means includes a portion adapted to abut the exterior skin and serve as a guide for an additional small incision, insertion of a tubular guide, placing a drill in the guide, drilling a second bore below the first bore and at an angle thereto. The pin includes a bore which is aligned with the tubular guide when in its second position and is adapted to receive a fastening means to lock the pin to the bone during the bone healing process.
