1. A method for implanting into a shoulder of a patient a modular humeral prosthesis which comprises an anatomical stem and an epiphyseal head, the method comprising the steps of:
using a gauge to measure retroversion angle of the shoulder to determine a desired angle of rotation to couple the epiphyseal head relative to the anatomical stem;
implanting the anatomical stem into a humerus of the patient;
attaching the epiphyseal head to the anatomical stem at the desired angle of rotation based on the measured retroversion angle, the anatomical stem and the epiphyseal head having complimentary mating surfaces, one of the mating surfaces having a peg extending therefrom and the other of the mating surfaces having a plurality of recesses for receiving the peg, each of the recesses corresponding to a predetermined angle of rotation of the epiphyseal head relative to the anatomical stem, immobilizing the epiphyseal head in rotation with respect to the anatomical stem at the desired angle of rotation by fitting the peg into an appropriate one of the recesses corresponding to the desired angle of rotation; and
locking the epiphyseal head to the anatomical stem via a screw passing through the epiphyseal head into the anatomical stem,
wherein the mating surface of the epiphyseal head is perpendicular to a longitudinal axis of the anatomical stem and extends laterally beyond the mating surface of the anatomical stem regardless of the angular orientation of the epiphyseal head with respect to the anatomical stem.
