ABSTRACT:
A drive system for a surgical fastener is composed of a drive tool with a drive tip that mates closely with the recess formed in the head of a threaded fastener. The surgical fastener has a head with a quadrilobe fitting therein which closely mates with the quardilobe tip of the tool. The cooperating drive surfaces align the fastener and tool coaxially and produce four point contact equidistant about the circumference of said fastener significantly reducing angular excursions of the fastener during placement in the bone.
