The shoulder girdle and upper arm are made up of a number of muscles and tendons: Various and complex capsular ligamentous structures contribute to the stability of the shoulder, but only a few can be adequately evaluated by US and will therefore receive particular attention.

Numerous serous bursae are situated among muscles, skin, subcutaneous tissues, joint capsule structures and bones to prevent friction and they can be evaluated by US only in the presence of pathologies. Subacromial-subdeltoid and subcoracoid bursa are most frequently involved and will therefore be described in detail.

There are furthermore nerves and vessels providing the various components of the shoulder with innervation and vascularization, and they can also be studied by US. The shoulder girdle humerus, scapula, clavicle and sternal manubrium is situated in the deep layers; only the cortex of the bone can be seen at US as a continuous hyperechoic line.

For a better understanding of the location and relationship between the structures which can be studied by US, magnetic resonance imaging MRI can be carried out as this method provides a wider and more complete view of the structures. Numerosi muscoli e rispettivi tendini partecipano al cingolo scapolo-omerale: Introduction The shoulder is a complex joint due to its anatomy and versatile range of movement, and it is therefore frequently affected by diseases of complex etiology [1,2].

Ultrasound US examination can thus not be exclusively dedicated to the study of the tendons, as tendon pathologies are often closely related to the functionality and stability of the shoulder joint [2]. For this reason, the US operator carrying out the examination of the shoulder must be thoroughly familiar with the anatomy of the structures which are normally studied by US, i.

The US operator should furthermore remember that the shoulder is made up not only of the scapulohumeral joint, but also of the acromioclavicular joint and functionally the sternoclavicular joint, where possible pathologies may cause shoulder pain [3].

This article therefore offers a complete revision of the US anatomy of the shoulder with images illustrating the various structures with integration of magnetic resonance imaging MRI and arthro-MRI in order to provide a better overall understanding of the anatomy.

Supraspinatus muscle The supraspinatus muscle arises from the central part of the supraspinatus fossa of the scapula; it laterally crosses the joint capsule and attaches to it, passes under the acromion and the coracoacromial ligament, then fans out horizontally and inserts to the superior and medial facets of the greater tuberosity of the humerus Fig.

The superficial part of the muscle is covered by the fascia supraspinata and enters in contact with the deltoid and trapezius muscles whereas the deep fascia attaches to the joint capsule. The tendon insertion to the greater tuberosity of the humerus is extended [1,5]. When contracted, it abducts and externally rotates the arm, and together with the deltoid muscle it also contributes to the stabilization of the shoulder joint.

It is innervated by the suprascapular nerve [1,4].GreenLeaf Farms Foundation of HOPE is a nonprofit organization that provides support services and resources for those using hemp products.
