In making a bone implant to immobolize and support bone structure damaged by a fracture or other localized impairment, as for example the ball joint region of a femur (hip bone), after the surgeon penetrates the flesh by an incision of small diameter, a tubular guide is inserted through the incision, a drill is introduced through the guide and operated to drill a bore in the bone, a measuring sleeve is slipped over the exposed part of the shank of the drill to assist in measuring the depth of the bore, the measuring sleeve and drill are removed, a threaded pin of correct dimension is introduced through the guide, and screwed into the bore of the bone by a pin driver working through the guide. The latter is then withdrawn from the incision.
