Abstract
A femoral head trial adaptor for converting a shell trial to a head trial includes a barrel member having an outer surface and an inner surface defining a cavity for receiving a femoral neck trial. A circumferential flange portion is located on the outer surface of the barrel member. A resilient connecting member disposed on the circumferential flange has a nominal first diameter compressible to a smaller second diameter in response to a force and returnable to the first diameter in the absence of the force for securing the trial adaptor to a shell trial. The flange may be located at a predetermined position along the outer surface of the barrel member so as to simulate a neck trial of a given length.
