Glenohumeral Joint

The GH joint is a diarthrodial joint with minimal bony constraint, allowing it the largest range of motion of any major diarthrodial joint in the body. The GH joint has been described as being similar to a golf ball on a tee, with a large humeral head balanced on a smaller glenoid.

The GH joint […]

Scapula

The scapula is a flat, triangular-shaped bone that serves as the articulating surface for the head of the humerus as well as provides areas for 17 muscle attachments. With the arm at the side, the scapula overlaps the dorsal surfaces of the second to seventh ribs. It has three prominent projections: the spine, the coracoid […]

Management-Techniques

The technique and approach of surgical decompression of the suprascapular nerve is dependent on the location of the presumed etiology of the nerve dysfunction. If the pathology is at the suprascapular notch, then the transverse scapular ligament and suprascapular notch may be approached anteriorly, superiorly, or posteriorly.

The anterior approach uses a saber-type incision, just […]

Biomechanics

During sports, repetitive microtrauma can damage the nerve in several ways, including entrapment and compression, traction and friction, direct trauma, as well as conditions affecting the brachial plexus in general. Besides direct effects on the nerve, intimal damage to the axillary or suprascapular artery has been proposed to result from direct trauma or friction that, […]

Anatomy

The suprascapular nerve originates from the fifth and sixth anterior cervical roots, which are part of the upper trunk of the brachial plexus. The suprascapular nerve typically is a motor nerve with no cutaneous sensory capabilities. It travels laterally, across the posterior cervical triangle, deep to the posterior belly of the omohyoid muscle and the […]
