Abstract
A bone anchor includes an anchor body configured to be retained within bone. The anchor body includes a restrictor defining an opening having a first portion for permitting passage of a member therethrough, and a second portion restricting passage of the member therethrough. The member is movable between the first and second portions in a direction non-parallel to a direction of passage of the member through the opening. The restrictor includes an edge lining the opening oriented obliquely to a direction of passage of the member through the opening. The anchor body includes one or more resilient members with sharp, proximal edges for penetrating bone tissue.
