Quadrilateral space syndrome is a rotator cuff denervation syndrome in which the axillary nerve is compressed at the quadrilateral space of the rotator cuff. Cause
The quadrangular space is a clinically important anatomic space in the arm as it provides the anterior regions of the axilla a passageway to the posterior regions. In the quadrangular space, the axillary nerve and the posterior humeral circumflex artery can be compressed or damaged due to space-occupying lesions or disruption in the anatomy due to trauma.
Fibrous bands, cysts of the glenoid labrum, lipoma or dilated veins can occupy the quadrilateral space pathologically. Similar symptoms are common with anterior shoulder dislocation, humeral neck fracture, brachial plexus injury and thoracic outlet and inlet syndrome. It is important to include those pathologies for a complete as possible ...

This syndrome can begin with severe shoulder or arm pain followed by weakness and numbness. [5] Those with Parsonage–Turner experience acute, sudden-onset pain radiating from the shoulder to the upper arm. Affected muscles become weak and atrophied, and in advanced cases, paralyzed. Occasionally, there will be no pain and just paralysis, and ...
The scenario, in which space debris collides and creates more debris, is called Kessler Syndrome. Eventually, the proliferation could make Earth’s orbit too clogged for satellites to orbit ...
Triangular Interval Syndrome (TIS) was described as a differential diagnosis for radicular pain in the upper extremity. [6] It is a condition where the radial nerve is entrapped in the triangular interval resulting in upper extremity radicular pain. The radial nerve and profunda brachii pass through the triangular interval and are hence vulnerable.
The phenomenon is known as Kessler syndrome, named after retired NASA engineer Don Kessler, who first proposed it mechanisms in 1978. RELATED STORY | Why Space Junk Is A Compounding Issue For ...
