Summary
Surgery for shoulder terrible triad (STT) improves functional outcomes. Rotator cuff tears and distal nerve injuries correlate with better results, while preoperative scores predict success.
Area of Science:
- Orthopedic Surgery
- Traumatology
- Sports Medicine
Background:
- The shoulder terrible triad (STT) involves anterior shoulder dislocation, rotator cuff (RC) tear, and brachial plexus nerve injury.
- Understanding functional outcomes and prognostic factors is crucial for surgical management of STT.
Purpose of the Study:
- To evaluate the functional results of surgical treatment for acute STT.
- To identify prognostic factors influencing surgical outcomes in STT patients.
Main Methods:
- Retrospective analysis of 30 consecutive patients with acute STT.
- Preoperative and postoperative assessment using Constant, WORC, ASES scores, and subjective shoulder value.
- Radiography, MRI, and electromyography for injury characterization.
Main Results:
- Significant improvement in WORC and Constant scores post-surgery (P=0.015 and P=0.003).
- Rotator cuff tears and injuries to nerves distal to the shoulder were associated with better outcomes.
- Preoperative WORC and Constant scores independently predicted functional success.
Conclusions:
- Surgical intervention for STT leads to improved functional scores.
- Specific injury patterns (RC tears, distal nerve involvement) and higher preoperative scores are linked to superior outcomes.
- Identifying these factors aids in patient counseling and surgical planning for STT.

01:23Muscles of the Shoulder
8.5K
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.

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...
