A modular prosthesis, such as a shoulder prosthesis, enables the selection of one of multiple alternate offset locations of a head member, such as a humeral head member, on a stem member, such as a humeral stem member, together with the selection of any rotational orientation of the head member within a full 360° range of rotational orientation relative to the stem member, so as to locate and orient the head member secured on the stem member for optimum replication of the natural joint replaced by the prosthesis.
