Summary
Isolated complete capsular tears cause recurrent anterior glenohumeral instability in 4% of cases. Surgical repair, particularly arthroscopic, effectively treats this condition, improving patient outcomes and shoulder stability.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Shoulder Instability Research
Background:
- Complete capsular tears are a known cause of anterior glenohumeral instability.
- The prevalence and clinical presentation of these tears require further elucidation.
Purpose of the Study:
- To determine the prevalence of isolated complete capsular tears.
- To assess clinical features and surgical treatment outcomes for recurrent anterior glenohumeral instability due to these tears.
Main Methods:
- Analysis of 303 shoulders treated for recurrent anterior glenohumeral instability over five years.
- Identification of 12 shoulders (4.0%) with isolated complete capsular tears.
- Assessment of patient demographics, injury mechanisms, preoperative findings (physical exam, CT arthrography), and surgical procedures (arthroscopic or open repair).
Main Results:
- Isolated complete capsular tears occurred in 4.0% of cases.
- Associated Hill-Sachs lesions were absent or small (chondral indentation type).
- Average Rowe score improved significantly from 30.4 to 90.4 postoperatively at 31 months.
Conclusions:
- Isolated complete capsular tears represent a significant cause (4.0%) of recurrent anterior glenohumeral instability.
- These tears are characterized by minimal or no Hill-Sachs lesions.
- Arthroscopic repair offers an effective treatment for recurrent anterior shoulder dislocation caused by complete capsular tears.

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...
