<p>An instrument (11) for harvesting an iliac bone graft comprises an elongate handle (13) having a proximal gripping portion (15) terminating in a substantially blunt striking surface (17), and a distal working portion (19) including a pair of longitudinally extending, transversely spaced apart retaining slots (21, 23). A pair of chisel-type blades (45, 47) are adapted for being releasably, lockably housed in the slots. The blades (45, 47) are retained in the slots by set screw (97) and by overhanging lips (57, 74) which engage the blades when fully inserted in the slots. An instrument (151) for inserting an iliac bone graft into a disc space comprises an elongate handle (153) having a proximal gripping portion (155) terminating in a substantially blunt striking surface (157), a distal working portion (159) including an enlarged abutment head (161) on its terminal end, and a slide portion (165) 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 (175) is disposed on the slide portion and is slidable between the abutment head and the gripping portion.</p> |
