FIXATIONSYSTEM FÜR EIN ORTHOPÄDISCHES BAND

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 radial 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.
