Abstract of the Disclosure A bone nailer (10) adapted for use with an elongate nail or screw like insert (20, 50, 60, 80) comprising a head portion (21, 51, 61, 81), and a smaller diameter embedable portion (25, 55, 65, 85) projecting from the head portion (21, 51, 61, 81). The nailer (10) includes a housing (28, 88) having an inner surface (29, 89) defining a through passageway with a portion of the inner surface (29, 89) adjacent an outlet opening (31, 91) of the passageway being adapted to receive the insert (20, 50, 60, 80) with its head portion (21, 51, 61, 81) farthest from the outlet opening (31, 91) and to guide the head portion (21, 51, 61,81) during movement of the insert (20, 50, 60, 80) through the outlet opening (31, 91). A driver (36, 96) having an end (37, 97) adapted to engage the head portion (21, 51, 61, 81) is mounted on the housing (28, 88) for sliding movement from a load position with the driver (36, 96) spaced from the outlet opening (31, 91) to afford positioning the insert (20, 50, 60, 80) in the passageway, along the passageway so that the end (37, 97) of the driver (36, 96) can push the insert (20, 50, 60, 80) toward the outlet opening (31, 91), to an eject position at which the driver (36, 96) has pushed the insert (20, 50, 60, 80) out the outlet opening (31, 91) so that drive means adapted to be manually activated can rapidly propel the driver (36, 96) along the passageway from its load to its eject position to rapidly move the insert (20, 50, 60, 80) through the outlet opening (31, 91) and embed its embedable portion (25, 55, 65, 85) in adjacent bone.
