Lesser Tuberosity Osteotomy Versus Tenotomy for Subscapularis Repair During Total Shoulder Arthroplasty
In Brief
A clinical study evaluating TSA with tenotomy technique, TSA with lesser tuberosity osteotomy technique, and 1 other intervention for Osteoarthritis. Completed, enrolled 60 participants across 1 site.
Detailed Summary
The primary objective of this study is to assess the clinical effectiveness of two different techniques used for subscapularis tendon repair during total shoulder replacement. The investigators hypothesize that participants who receive a newer repair technique called a lesser tuberosity osteotomy will have lower rates of postoperative subscapularis muscle dysfunction and rupture as compared to those who receive the traditional tenotomy repair.
Study Details
Timeline
Interventions
Standard procedure: Utilization of tenotomy for mobilization of subscapularis during total shoulder arthroplasty (TSA). The subscapularis tendon is incised close to its attachment on the humerus. The Tendon is repaired with sutures.
Standard procedure: Utilization of the osteotomy to mobilize the subscapularis during TSA. A small fleck of bone is removed from humerus, the subscapularis tendon is still attached. The fleck of bone is reattached with sutures.
Standard procedure: Total shoulder arthroplasty replaces both components of the "ball and socket" joint with a metal device.
