  • Patent number: 4653486
    Abstract: A method and apparatus for fastening one element to another, particularly adapted for orthopedic use, wherein the fastener is structurally adapted to be driven into a member somewhat like a nail and to be secured therein by rotating the fastener through a predetermined angular displacement to secure threads on the fastener in the thus-fastened member. The fastener is thus readily removable by counter-rotating the device a like amount. In one embodiment, the fastener includes a head portion structurally adapted to receive a force axially applied to the fastener, a tip portion structurally adapted for leading the fastener into a member to be fastened, and a shank portion disposed between the head portion and the tip portion. The shank portion includes a thread-bearing zone and a thread-free zone circumferentially spaced about the shank portion which together comprise the entire circumference of the shank.
