Study of the Functional Result of the Reinsertion of the Subscapular in Reverse Shoulder Prostheses According to the Healing of the Subscapular

This study is based on the hypothesis that the functional result is better if the subscapularis is reinserted and healed. The originality of the study therefore consists in systematically monitoring the healing of this tendon postoperatively, with sufficient follow-up, by ultrasound and by an intra-tendon marker, in order to differentiate the result depending on whether the tendon is healed or not.
