ABSTRACT:
An implantable orthopedic prosthesis. A prosthetic component includes a wall having a first surface for engaging bone and a second surface. The wall defines a hole therethrough extending from the second surface to the first surface. A plug is removably disposed in the hole. The plug includes a peripheral rim spring-biased radially outwardly in frictional engagement with the sidewall of the hole. The plug is useful for occluding the hole to alleviate the risk of polyethylene wear particles migrating through an unused hole into contact with bone.
