Abstract
A bone anchor system including a bone anchor having an integral head, a stabilization member, and a coupling member molded around the integral head of the bone anchor is provided for coupling the bone anchor to the stabilization member. The coupling member includes an interface to the stabilization member. Advantageously, the interface to the stabilization member is made of a deform able material to reduce surface stress concentration in the stabilization member. The interface of the coupling member may be integral to the coupling member, or the interface may be an interface piece that may be inserted into the coupling member. The integral head of a bone anchor may include a molded cap that is formed from a deformable material and configured to provide an interface to the stabilization member.
