  • Patent number: 5403321
    Abstract: A radiolucent drill guide for connection to the proximal end portion of an intramedullary nail for aligning a drill with bores of an intramedullary nail when the nail is surgically positioned within a intramedullary canal of a patient includes a handle member of radiolucent material and a guide barrel imbedded within the handle. The handle includes an inner generally cylindrical bore and an outer surface that is bonded to closely surround the radiolucent material of the handle member so that the barrel does not rotate freely relative to the handle. The guide barrel includes flanges for preventing relative movement of the barrel in the direction of the central longitudinal axis of the bore of the barrel. A plurality of openings in the handle are at positions spaced away from the barrel for guiding drills when the barrel is affixed to the intramedullary nail so that the drills align with selected openings of the intramedullary nail.
