Reverse Total Shoulder Arthroplasty with Conjoint Tendon Resection
For RTSA using a deltopectoral approach, the Perform glenoid and humeral components of Tornier Stryker Reverse Shoulder system will be used for all cases. The sizes and offsets of the components will be chosen based on each patient's local anatomy which will vary among patients. The subscapularis tendon will be repaired using three transosseous nonabsorbable sutures whenever there is a reparable subscapularis tendon. After definitive implantation of the prosthesis is completed, in the 'no interventional' group, the wound will be closed in layers, and the shoulder will be immobilized in an abduction sling.
RTSA in the experimental group will be identical, except for that after definitive implantation of the prosthesis is completed, in the 'experimental' group, the conjoint tendon will be released completely via a transverse incision made at a level 2 cm distal to the coracoid process for the patients assigned the conjoint resection group. Electrocautery will be used for the resection, and the underlying muscular portion of the conjoint tendon will be preserved. As mentioned above, the control group will not receive this conjoint tendon resection. Similarly, in the experimental group, the wound will be closed in layers, and the shoulder will be immobilized in an abduction sling.
