Abstract
An anti-displacement device and method are disclosed for implantation of a prosthetic bone joint in a bone. A biodegradable biocompatable anti-displacement device comprising a biodegradable biocompatible polymer is directed through an orifice, defined by a cup of a prosthetic bone joint, and into interfering contact with bone tissue of the bone. Displacement of the cup is thereby sufficiently limited to allow bone tissue growth at the cup to fix the prosthetic bone joint to the bone while body fluid at the bone tissue and contacting the elongate member biodegrades the elongate member.
