A humeral prosthesis includes a stem component and a humeral head component. The humeral head component has a configuration that is similar to the curvature of the humeral head to allow the head to reconstruct the anatomy of the damaged humerus. The stem component is threaded and cannulated and engages the humeral head component. The stem component is configured to be inserted within the humeral diaphyseal channel. When engaged the humeral head component and the stem component form an articulated joint allowing the humeral head component to articulate with respect to the stem component.
