Abstract
A locking clip for retaining a fastener in a bone fixation plate, the locking clip comprising a flexure member and a body member coupled to the flexure member, the body member comprising a locking tab, the locking tab configured to provide an axial limitation to motion of the fastener in a non-rotationally-ratcheting manner, the flexure member resiliently flexible to permit displacement of the locking tab to allow passage of a fastener head of the fastener, the locking tab configured to translate a downward force of the fastener head into a lateral spreading force to effect the displacement, the body member defining a clip tool engagement cavity for translational displacement of the locking tab.
