Figure 1. The measurements of the normal glenohumeral relationships. Distance H-I represents the position of the joint line of the glenoid from the base of the coracoid. The lateral glenohumeral offset is represented by distance F-H. (Reprinted with permission.^[9])

Figure 2. Humeral stems that reference the longitudinal axis may be placed eccentrically with respect to the rotator cuff (A). Downsizing the humeral stem and cementing it centrally with respect to the rotator cuff allows anatomic placement of the humeral head with respect to the rotator cuff.

Figure 3. Tornier prosthesis incorporates medial offset in the humeral stem and the eccentric humeral head positions to reconstruct native anatomy.
