Patent ID: 8152855

Claim:
A method of installing a femoral sleeve prosthesis to a femoral head comprising: preparing an outer surface of the femoral head about a datum to a predetermined configuration to create a prepared femoral head having a head axis defined by the datum; selecting a sleeve prosthesis having a distal end with an opening into a cavity and a proximal end having an aperture, the cavity being sized and configured to engage the outer surface of the prepared femoral head; inserting the sleeve prosthesis into a sleeve interface of a tool and retaining the sleeve prosthesis in the sleeve interface, the tool further comprising a guide and a handle, the guide capable of aligning the sleeve interface with the head axis when engaged with the datum and guiding the sleeve interface to slidingly translate along the head axis when engaged with the datum, the handle capable of applying force to the interface portion; engaging the guide of the tool with the datum; applying force to the tool handle to slidingly translate the tool and sleeve prosthesis along the head axis to seat the sleeve cavity on the prepared femoral head surface; and releasing the sleeve prosthesis from the sleeve interface, disengaging the guide from the datum and removing the tool, wherein the datum is a guide wire bore, and the guide comprises a pin extending from the sleeve interface, the pin being configured to slidingly fit in the guide wire bore when the pin is engaged with the guide wire bore by passing the pin through the aperture and cavity of the sleeve prosthesis when inserting the sleeve prosthesis into the sleeve interface and then positioning the tool to place the pin into the guide wire bore.
