HOLE CAPS FOR PROSTHETIC IMPLANTS

摘要

The disclosed hole cap (110) supports a prosthesis and provides a physical barrier between the prosthesis and underlying bone matter. In a preferred embodiment, the hole cap includes at least one compression spring (120) formed along the cap perimeter to maintain the hole cap within a counter-bored hole (112). The compression spring deflects slightly towards the center of the hole cap and provides sufficient compression force against the sidewalls of the counter-bored hole to thereby hold the hole cap in place within the hole. With the use of bone screws (104) or otherwise, the hole caps cover holes in implants to prevent the flow of unwanted debris into the counter-bored hole and into the underlying bone matter.
