MRI showing subacromial impingement with partial rupture of the supraspinatus tendon, but no retraction or fatty degeneration of the supraspinatus muscle. Impingement syndrome can be diagnosed by a targeted medical history and physical examination , [ 11 ] [ 12 ] but it has also been argued that at least medical imaging [ 13 ] (generally X-ray ...
Thoracic outlet syndrome (TOS) is a condition in which there is compression of the nerves, arteries, or veins in the superior thoracic aperture, the passageway from the lower neck to the armpit, also known as the thoracic outlet. [1] There are three main types: neurogenic, venous, and arterial. [1]
Subacromial bursitis is a condition caused by inflammation of the bursa that separates the superior surface of the supraspinatus tendon (one of the four tendons of the rotator cuff) from the overlying coraco-acromial ligament, acromion, and coracoid (the acromial arch) and from the deep surface of the deltoid muscle. [1]
Abduction is carried out by the deltoid and the supraspinatus in the first 90 degrees. From 90-180 degrees it is the trapezius and the serratus anterior. Adduction is carried out by the pectoralis major, latissimus dorsi, teres major and the subscapularis. Horizontal abduction and horizontal adduction of the shoulder (transverse plane)

The impinged structures include the supraspinatus muscle, teres minor muscle, and the infraspinatus muscle. The Hawkins–Kennedy test is considered to be a highly sensitive test (79%) [ 3 ] and thus a positive Hawkins–Kennedy test suggests that injury is likely.
Such severe spinal stenosis symptoms are virtually absent in lumbar stenosis, however, as the spinal cord terminates at the top end of the adult lumbar spine, with only nerve roots (cauda equina) continuing further down. [15] Cervical spinal stenosis is a condition involving narrowing of the spinal canal at the level of the neck.
Stenosis (from Ancient Greek στενός (stenós) 'narrow') is the abnormal narrowing of a blood vessel or other tubular organ or structure such as foramina and canals. It is also sometimes called a stricture (as in urethral stricture ).
