Summary
This study introduces a novel technique for subscapularis repair after total shoulder arthroplasty (TSA) using a peel-tenotomy and bone marrow aspirate concentrate (BMAC). The method aims to enhance subscapularis repair robustness and reduce post-operative insufficiency.
Area of Science:
- Orthopedic Surgery
- Biologics in Musculoskeletal Repair
Background:
- Subscapularis insufficiency is a significant complication following anatomic total shoulder arthroplasty (TSA).
- Biologic augmentation strategies have shown promise in enhancing rotator cuff repair outcomes.
Purpose of the Study:
- To describe a surgical technique for subscapularis repair after TSA.
- To investigate the use of a peel-tenotomy and bone marrow aspirate concentrate (BMAC) for subscapularis augmentation.
Main Methods:
- A standard deltopectoral approach was utilized.
- A peel-tenotomy involved detaching most of the subscapularis tendon from the lesser tuberosity.
- Bone marrow was aspirated from the humeral head, processed, and applied to the repair site before and after suture fixation using a double-row technique.
Main Results:
- The described technique facilitates a secure double-row subscapularis repair.
- Bone marrow aspirate concentrate (BMAC) is applied to augment the tendon repair.
Conclusions:
- The described technique offers a method for robust subscapularis repair after TSA.
- This approach may potentially decrease subscapularis insufficiency rates following TSA, though further research is warranted.

01:23Muscles of the Shoulder
The muscles surrounding the shoulder girdle, including the clavicle and scapula, primarily stabilize the scapula. This stable base allows other muscles to move the humerus effectively. Scapular movements often mirror those of the humerus and extend its range of motion. For instance, raising the arm above the head would not be feasible without simultaneous upward rotation of the scapula.

01:31Muscles that Move the Arm
Nine muscles are involved in arm movements. Two of these, the pectoralis major and latissimus dorsi, originate from the axial skeleton and are called axial muscles. The other seven originate from the scapula and are called the scapular muscles.
The pectoralis major has two origins. Its clavicular head originates on the medial half of the clavicle. In contrast, the sternocostal head originates on the costal cartilages of ribs 1-6, the sternum, and the aponeurosis of the external oblique of the...
