Methods and apparatus facilitate the positioning of a prosthetic element relative to a bone so as to achieve a desired orientation. An anchoring unit rigidly attaches to a point of the bone surrounding a region associated with receiving the prosthetic element, and at least one structural member is used to physically couple the prosthetic element to the anchoring unit. The combination of the anchoring unit and structural member includes one or more fasteners which may be loosened to temporarily remove the prosthetic element once a desired orientation is achieved, while facilitating re-installation of the element in accordance with the desired orientation following the temporary removal. In a preferred embodiment, the prosthetic element is an acetabular implant, and the surrounding bone forms part of a human pelvis. Regardless of the application, the element may take the form of a trial or a final implant. |
