ORTHOPAEDIC LIGAMENT FIXATION SYSTEM

摘要

A ligament fixation system comprising an expandable screw (11) with an atraumatic thread. The screw is expanded by insertion of an expansion screw (12) into a threaded longitudinal bore of the expandable screw to cause radi al expansion of the screw. The system includes an insertion tool (32) having an outer sleeve (33) for insertion of the expandable screw and an inner relatively rotatable member (39) for insertion of the expansion screw. The tool includes a torque gauge. The invention extends to methods of fixing a tendon graft in a bone tunnel.
