Abstract

A bone fastener for use in orthopedic surgery for fixing an implant to bone includes a shaft and a head. The shaft is configured to drive into bone when rotated in a first direction. The head is formed on one end of the shaft and has proximal and distal sections. The head also has at least one cutting flute on the distal section of the head. The bone fastener may be used with a prosthetic implant, such as an acetabular shell or bone plate. In use, the bone fastener is driven into the bone through a hole in the prosthetic implant, with at least a portion of the head protruding beyond the hole of the implant. As the head is driven beyond the hole of the implant, the cutting flutes in the head help secure the head of the bone fastener into the bone, increasing the stability of the system.
