Modular humeral head

A method of assembling an articular component of a prosthetic shoulder joint, the method comprising:

• engaging an end of a coupler of a joint implant with a coupling portion of another component of the joint implant;
• providing relative rotation between the end of the coupler and the coupling portion of the other component of the joint implant along a continuous range of rotational positions while the end is engaged with the coupling portion of the other component of the joint implant;
• selecting an amount of eccentricity corresponding to a position within the continuous range of rotational position;
• and
• securing the other component of the joint implant to the end of the coupler at the selected amount of eccentricity.

A method of disassembling a humeral prosthesis, comprising:

• exposing a periphery of the humeral prosthesis such that a gap between an articular body and a humeral anchor is accessible;
• advancing a prying tool into the gap;
• further advancing the prying tool against a prying ledge formed on a coupler disposed between the articular body and the humeral anchor until contact is made with the prying ledge;
• and
• applying a radial load to the prying ledge at an end of the prying tool, the prying ledge being angled relative to a direction of application of the radial load, whereby the radial load results in an axial load causing the articular body to be separated from the humeral anchor.
