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.

Neer test for subacromial impingement. The Neer impingement test is a test designed to reproduce symptoms of rotator cuff impingement through flexing the shoulder and pressure application. Symptoms should be reproduced if there is a problem with the supraspinatus or biceps brachii. [1]
Impingement of the shoulder was previously thought to be precipitated by shoulder abduction and surgical intervention focused on lateral or total acromionectomy. [ 4 ] [ 25 ] In 1972, Charles Neer proposed that impingement was due to the anterior third of the acromion and the coracoacromial ligament and suggested surgery should be focused on ...
The Neer classification of proximal humerus fractures is the most commonly used classification system. It classifies fractures depending on the number of segments (2-4 parts), and whether or not there is displacement present.
Palpation of sternoclavicular joint, clavicle, acromioclavicular joint, subacromial bursa, bicipital tendon. Evaluation of passive and active range of motion: Neck range of motion should be assessed that may reveal a neck source of shoulder pain. The Apley scratch test specifically tests range of motion and in a normal exam, an individual ...
The lateral fragment of the clavicle during a fracture is depressed by the weight of the arm and is pulled downward by the strong abductor muscles of the shoulder joint, especially the deltoid. The part of the clavicle near the center of the body is tilted upwards by the sternocleidomastoid muscle. Children and infants are particularly prone to it.
The shoulder joint is made up of three bones: the shoulder blade (scapula), the collarbone (clavicle) and the upper arm bone (humerus). The acromion is a bony process at the end of the scapula The shoulder is a complex mechanism involving bones, ligaments , joints , muscles , and tendons .
A significant bump, resulting in some shoulder deformity, is formed by the lateral end of the clavicle. This bump, caused by the clavicle's dislocation, [5] is permanent. The clavicle can be moved in and out of place on the shoulder. A radiographic examination will show the results as abnormal. [medical citation needed]
