Abstract:
A method for centering of a prosthesis in a cavity formed on an upper proximal surface of a bone, the prosthesis including a stem having a direction of elongation and being configured to fit into the cavity formed on the upper proximal surface of the bone, and a neck extending away from an upper surface of the stem, said method comprising the steps of:inserting the stem into the cavity formed on the upper proximal surface of the bone;mounting a device onto the neck of the prosthesis;inserting projections disposed on a lower surface of the device into previously formed slots on the upper proximal surface of the bone, the slots being structured and located such that when the projections are seated therein, the stem is substantially centered in the cavity on the upper proximal surface of the bone; andremoving the device from the neck of the prosthesis by the application of a force on the device directed away from the stem.
