Cannulated locking bone fastener

Abstract

A bone fastener system including a bone fastener having cavities for receiving locking screws traverse to a longitudinal axis. The bone fastener includes a proximal end connected to a head, a distal end and an elongated shank defining a longitudinal axis. The elongated shank has an inner surface defining an inner cavity extending from the proximal end to the distal end along the longitudinal axis. The inner cavity is configured to receive a guide wire. The system includes a first locking screw and the bone fastener further comprises a second cavity defined by an inner surface disposed at an angle transverse to the longitudinal axis configured to receive a first locking screw.
