摘要：
A system for anchoring implants to bones comprises a screw and fixation collar that when connected together inhibit axial movement of the screw and that when connected to an implant with a compatibly shaped aperture inhibit the screw's ability to back out from the bone and back out from the implant. The fixation collar includes a substantially C-shaped configuration partially surrounding a void, with first and second ends defining a gap that is slightly narrower in width than the diameter of the screw and being partially flexible to allow compression and expansion of the fixation collar to snap fit the collar around the screw.
