Fastener for a modular implant

摘要

A joint between an implant body component and a stem component provides an initially rigid connection that further remains rigid even if the joint settles upon being loaded. The body and stem have portions comprising a male/female taper junction. A fastener maintains the taper junction in tight engagement. The fastener engages the implant components and draws them together. The fastener includes a resilient portion that deflects such that if settling occurs, the resilient portion maintains compressive contact between the fastener and the components.
