ABSTRACT:
An instrument for holding and guiding a wire that is being drilled through the piriformis sinus in the trochanteric region is disclosed, the drilled canal thus formed serving as an entryway into the intermedullary canal of the femur for stabilizing femoral fractures. The instrument includes spaced post members with grooves formed therein to provide a straight path into the sinus and to stabilize the flexible drilling wire for avoiding eccentric movement of the wire during drilling.
