Bones of the Shoulder

Shoulder is the meeting place of three bones viz. clavicle, scapula and humerus.  The junction of these three bones and the chest bone (sternum) form three joints: Glenohumeral joint:  It is the shallow ball-and-socket style joint created by the humerus and scapula.  This joint allows the arm to rotate circularly and to move up and out of the body.  Glenohumeral joint is surrounded by soft tissue and strengthened by fibrous ligaments. Acromioclavicular joint (AC joint):  This joint is the highest point of the shoulder.  It is because of this joint that we are able to raise the arm above the ...

Axillary Nerve Palsy and Shoulder Dislocation

Axillary nerve palsy is a condition marked by loss of movement or sensation in the shoulder area. There are so many reasons for axillary nerve palsy, but the prominent one is shoulder dislocation. Axillary nerve’s close proximity to the shoulder capsule puts it at risk for injury. It is also known as axillary neuropathy and mononeuropathy as it is a problem with just one nerve. Excessive stress or damage to the axillary nerve, which serves the deltoid muscles and skin of the shoulder, causes axillary nerve palsy. Dysfunction of the axillary nerve can occur in the myelin sheath which provides ...

Paralabral Cyst in the Shoulder

More often than not, paralabral cysts of the shoulder are an infrequent finding on MRI or MR Arthrogram. However, it is a significant diagnosis as they may cause a compression neuropathy of the suprascapular or axillary nerves depending on where they occur, along with a variety of other symptoms. About 2-4% of the general population is likely to have it and presentation may be common in males (especially around the third to fourth decades). On average, this cyst measures 10–20 mm in diameter and are located mainly on the posterosuperior aspect of the glenoid. These cysts may represent a synovial ...
