Stress analysis of glenoid component in design of reverse shoulder prosthesis using finite element method.
The authors created a 2D finite element model of a human shoulder and 'implanted' reverse total shoulder in various configurations. They noted that both distal placement and increased lateral offset of glenosphere induce higher stress at the glenoid-baseplate junction. Increased offset and inferiorly tilting the baseplate resulted in higher stresses in the glenoid screws. The inferior screw attained more stress than the superior screw, especially at its base. Direct contact of the humeral component associated with scapular notching may accentuate the risk of failure at the middle of the inferior screw.
This result is consistent with our previous publication that emphasizes the importance of excellence of baseplate-bone contact and the quality of fixation of the screw nearest the point of load application.
