Abstract

An instrument for harvesting an iliac bone graft comprises an elongate handle having a proximal gripping portion terminating in a substantially blunt striking surface, and a distal working portion including a pair of longitudinally extending, transversely spaced apart blade retaining slots. A pair of chisel-type blades are adapted for being releasably, lockably housed in the slots. The blades are retained in the slots by set screws, and by overhanging lips which engage the blades when fully inserted in the slots. An instrument for inserting an iliac bone graft into a disc space comprises an elongate handle having a proximal gripping portion terminating in a substantially blunt striking surface, a distal working portion including an enlarged abutment head on its terminal end, and a slide portion disposed between the gripping portion and the working portion, the abutment head having a distal abutment surface for engaging an iliac bone graft. A retainer member is disposed on the slide portion and is slidable between the abutment head and the gripping portions. The retainer member includes a pair of retaining fingers having proximal ends mounted on the retainer member and free distal ends which extend distally beyond the abutment surface of the abutment head when the retaining member is in its distalmost position. The distal ends of the retaining fingers are spring biased toward one another. The abutment head has stop lugs disposed on side extensions for limiting the travel of the abutment head into a disc space.
