The rotator cuff is the dominant contributor to stability throughout the midranges of motion through the concavity compression mechanism. In conclusion, pathomechanics of frozen shoulder characterized by glenohumeral joint limitation has a complicated pathogenesis made with the contracture of glenohumeral capsule, the periscapular stiffness, and the imbalance of strength of muscles surrounding the scapula. The head of the humerus is much larger than the glenoid fossa, giving the joint a wide range of movement at the cost of inherent instability. Factors preventing downward dislocation of the adducted shoulder joint. and Pathomechanics in the Throwing Athlete W. Ben Kibler, MD Medical director W. Ben Kibler, MD Shoulder Center of Kentucky Disclosure: I do not have a relevant financial relationship. Most shoulder motion occurs at the ball-and-socket glenohumeral joint, but for full motion of the shoulder, the acromioclavicular joint must also be functioning normally. The comprehensive kinetic chain examination can evaluate sites of kinetic chain breakage, and a detailed shoulder examination can assess joint internal derangement of altered physiology that may contribute to the pathomechanics.

Pathomechanics of Structural Foot Deformities. Chapter 8: Structure and Function of the Bones and Joints of the Shoulder Complex. As a consequence the shoulder joint is highly mobile, where stability takes second place to mobility, as is evident from the shape of the osseous structures: a large humeral head lying on an almost flat scapular surface. The “disabled throwing shoulder” (DTS) is a general term that describes the limitations in function that exist in symptomatic overhead athletes. 2012 Mar;20(1):16-21. doi: 10.1097/JSA.0b013e31823a021f. 1.
