COR lateralization had no influence on ROM (adduction or external rotation) but significantly increased abduction and dislocation forces. This suggests the lower incidence of scapular notching may not be related to the amount of adduction deficit after lateral offset RSA but may arise from limited impingement of the humeral component on the lateral scapula due to a change in joint geometry. Lateralization provides the benefit of increased joint stability, but at the cost of increasing deltoid abduction forces.
Modification of the initial concept of Paul Grammont with a moderate lateralization of the center of rotation around 8.5 mm by BIO-RSA provides good function. Grafting of the glenoid surface during RSA effectively creates a long-necked scapula, providing the benefits of lateralization. Bony increased-offset RSA is associated with low rates of inferior scapular notching, improved shoulder rotation, no prosthetic instability and improved shoulder contour. In contrast to metallic lateralization, bony lateralization has the advantage of maintaining the prosthetic center of rotation at the prosthesis-bone interface, thus minimizing torque on the glenoid component. There is an increase in active rotation (especially in external but also in medial rotation), with considerable impact on the quality of life of these elderly people. The absence of glenoid notching suggests long prosthesis survival, but it is too early to make any
assertion about the longevity of these“ less medialized”RSA prostheses.
