Abstract
A humeral prosthetic device having a body, a stem for anchoring the device in a humeral canal of a humerus, and a head for replacing a natural humeral head of the humerus. The head is disposed at a selected angle relative to the stem and at least one of the body and stem may control the selected angle of the head relative to the stem. Further, the stem may include an extension for coupling the stem to the body. The extension may be disposed on an axis parallel to and offset from a center line of the stem for providing a lateral offset of the body relative to the stem upon reversal of the stem in the humeral canal. The humeral prosthetic device may further include an insert which coacts with the body and the head of the device to provide superior, inferior, anterior, and posterior positioning of the head relative to the body.
