Clinical anatomy The joints of the shoulder–acromioclavicular, sternoclavicular, glenohumeral, scapulothoracic joints, which rely on associated muscles–eg, those attached to the scapula, to provide dynamic stability.

The shoulder joint, also known as the glenohumeral joint, is a ball and socket joint with the most extensive range of motion in the human body. The shoulder muscles have a wide range of functions, including abduction, adduction, flexion, extension, internal and external rotation.[1]The central...

Mobility has its price, however. It may lead to increasing problems with instability or impingement of the soft tissue or bony structures in your shoulder, resulting in pain. You may feel pain only when you move your shoulder, or all of the time. The pain may be temporary or it may cont...

Bony anatomy of the shoulder The humerus The humeral head is the “ball” part of the ball and socket. It is made up 4 of components: Rounded joint surface – the head of the humerus which sits in the socket (glenoid) to form the shoulder joint. ...
joint injury due to excessive distal clAVicle resection and detachment of the AC ligaments shortens the bony strut and allows excessive scapular internal rotation due to excessive anterior/posterior motion at the AC joint. The protracted scapular position creates many of the dysfunctional problems ...
The shoulder is the most mobile and least stable joint of the human body. The bony anatomy determines a very limited stability, which has to be maintained by the surrounding soft tissues that act as static stabilizers. In addition, dynamic stability is provided by the musculotendinous units of...
the sternoclavicular joint represents the only bony articulation between the upper extremity and the thoracic wall. Its motion characteristics are intimately tied to the scapula, such that each clavicular motion requires a movement on the part of the scapula. The clavicle is capable of three types ...
while bony and tissue derangement issues such as AC joint or clAVicle injury, labral injury, rotator cuff disease, or glenohumeral instability must be repaired. Rehabilitation can then proceed on the optimised anatomy. A very effective protocol can be based around the protocol suggested by Ellenbecke...
