Summary
Glenohumeral stability relies on dynamic and static factors. Disruption of these elements in the shoulder joint leads to instability and dysfunction.
Area of Science:
- Orthopedic Surgery
- Biomechanics
- Sports Medicine
Background:
- The glenohumeral joint is crucial for shoulder mobility.
- Understanding glenohumeral instability is vital for effective treatment.
- Numerous factors contribute to shoulder stability.
Purpose of the Study:
- To review biomechanical factors ensuring glenohumeral stability.
- To explore pathologic mechanisms of glenohumeral instability.
Main Methods:
- A comprehensive review of English medical literature.
- Focused on pathologic factors in glenohumeral instability.
Main Results:
- Glenohumeral instability is regulated by multiple dynamic and static factors.
- Normal shoulder anatomy and biomechanics are key to understanding instability.
Conclusions:
- Dynamic and static factors work together for glenohumeral joint stability.
- Disruption or malfunction of these factors causes shoulder dysfunction.

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...
