Patients usually present rotator cuff tendinopathy, frozen shoulder, axillary neuropathy and suprascapular neuropathy. This article presents an overview of the anatomy of the shoulder region and associated pathologies, whilst providing a summary of the clinical examination of the shoulder and associated ‘special tests’. The subacromial bursa (SAB) is the main bursa of the shoulder. The shoulder girdle is composed of three bones (the clavicle, scapula, and proximal humerus) and four articular surfaces (sternoclavicular, acromioclavicular, glenohumeral, and scapulothoracic) ( figure 1A-C ). Frozen shoulder, also called adhesive capsulitis, is a painful condition in which the movement of the shoulder becomes limited.

Postgraduates and practicing surgeons will find it beneficial to revise anatomy. Subdeltoid Bursa: between the Deltoid muscle and the shoulder joint cavity. Clin Anat. White, shiny, flexible bands of fibrous tissue that hold joints together and connect various bones, including: Joint capsule. Clinical anatomy of the subacromial and related shoulder bursae: A review of the literature. The subacromial-subdeltoid bursa (SASD) is a potentially pain-sensitive structure of the glenohumeral joint. In this video applying anatomy and surface anatomy to your assessment and treatment of the scapula-thoracic and gleno-humeral joints, David Pope of Clinical Edge explores the shoulder joint complex, while breaking it down into a practical and understandable video. A second joint in the shoulder is the junction of the collar bone with the shoulder blade, called the acromioclavicular joint. The glenohumeral joint is by far the most commonly dislocated joint of the body, accounting for up to 45% of dislocations.

The authors explore the anatomy of the glenohumeral joint and the surrounding structures that contribute to the function of the joint. However, the shoulder’s relative instability is associated with great mobility, whereas the stability of the hip joint results in a much smaller range of movements compared to the shoulder (Figure 4). Anatomical variation of shoulder bursae has been suggested and this has implications for clinical practice. The glenohumeral joint is a relatively unstable joint because of the very shallow glenoid fossa and the large humeral head compared to the much more stable hip joint. Stability is provided mainly by ligaments, tendons and muscles; the bones and capsule are of secondary importance. Shoulder dislocations. 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 shoulder joint is complex in structure and functionality. The shoulder joint (glenohumeral joint) is a ball and socket joint between the scapula and the humerus. Dear Medicos, ⚕️⚕️Please watch this lecture and must share with your friends Clinical anatomy of the elbow and shoulder Reumatol Clin.

It is often difficult to assess clinically due to the great variety of associated pathology. The shoulder joint (or glenohumeral joint from Greek glene, eyeball, + -oid, 'form of', + Latin humerus, shoulder) is structurally classified as a synovial ball and socket joint and functionally as a diarthrosis and multiaxial joint. Chris Mallac explores the role of the subacromial-subdeltoid bursa in the glenohumeral joint and provides diagnosis and treatment options. • Helps control humeral head movement • Rotator Cuff contraction, they dynamically tighten the capsule – Helps center the humeral head relative to the glenoid. An alternative explanation for persistent shoulder pain is that the source of the pain is of neural origin. This is not always the case. Frozen shoulder occurs when the strong connective tissue surrounding the shoulder joint (called the shoulder joint capsule) become thick, stiff, and inflamed. 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.
