Abstract
A humeral prosthesis allows a surgeon to adjust humeral head position thereof in three-dimensional space with respect to a humeral component of the humeral prosthesis that has been either previously implanted into a humerus of a patient or not. The humeral prosthesis includes a conjoining component that is configured to releasably mate with the humeral component and to releasably mate with a humeral head. The conjoining component allows the humeral head to be selectively positionable from continuously infinite positions about two orthographic axes with respect to the conjoining component. The selected spatial position of the head is locked by a locking member of the conjoining component. The conjoining component allows the use of various sized heads, allow in vivo head trialing and/or exchange, and retrofit of heads for previously implanted shoulder prosthesis in need of revision.
