About Dynamic Stability Factors of Glenohumeral (Shoulder) Joint

What is Glenohumeral (Shoulder) Stability? Glenohumeral (Shoulder) stability is mainly achieved through dynamic factors. Active contraction of the rotator cuff contributes to joint stabilization by coordinated muscular activity and by secondary tightening of the ligamentous constraints. This effect works in combination with the concavity-compression mechanism, in which muscle contraction causes compression of nearly congruent articular …

Biomechanics of Shoulder Stability (Static Stability Factor)

The glenohumeral (shoulder) joint is inherently unstable, with the large humeral head articulating with the small and shallow glenoid. Static stability is provided by the orientation of the articular surfaces, the articular conformity of humerus and the glenoid, the glenoid labrum, the negative intra-articular pressure, the adhesion-cohesion of synovial joint fluid, and the glenohumeral joint …
