ROBOTIC BONE PREPARATION FOR INCREASING IMPLANT CONTACT SURFACE AREA

摘要

Described herein is a bone implant (100) including at least one bone-engaging surface designed to mate with an implant-engaging surface of a bone. In the preferred embodiment, the bone-engaging surface of the implant includes a wave pattern comprising at least one peak (112) extending in a proximal direction (P) and at least one valley (115) extending in a distal direction (D). The implant-engaging surface of the bone also includes a matching wave pattern having at least one peak and valley. Upon mating the engaging surfaces, a bone-implant interface may be created wherein the peaks and valleys of the wave patterns are aligned. As a result, there is good surface contact area at the bone-implant interface which helps prevent loosening or rotating of the implant.
