Adhesive capsulitis (AC), also known as frozen shoulder, is a condition associated with shoulder pain and stiffness. [1] It is a common shoulder ailment that is marked by pain and a loss of range of motion, particularly in external rotation. [3] There is a loss of the ability to move the shoulder, both voluntarily and by others, in multiple ...
The shoulder joint involves articulation between the glenoid cavity of the scapula (shoulder blade) and the head of the upper arm bone and functions as a diarthrosis and multiaxial joint. Due to the very loose joint capsule that gives a limited interface of the humerus and scapula, it is the most mobile joint of the human body.
The shoulder joint has a very loose joint capsule, which can sometimes predispose the shoulder to dislocate. [citation needed] The "U shaped" dependent portion of the axillary part of the capsule ,located between the anterior and posterior bands of inferior glenohumeral ligament, is called "axillary pouch". [3]
In some cases, arthroscopic surgery is not enough to fix the injured shoulder. When the shoulder dislocates too many times and is worn down, the ball and socket are not lined up correctly. The socket is worn down and the ball will never sit in it the same. After many dislocations the shoulder bones will begin to wear down and chip away.
A fracture in this area is most likely to cause damage to the axillary nerve and posterior circumflex humeral artery. Damage to the axillary nerve affects function of the teres minor and deltoid muscles, resulting in loss of abduction of arm (from 15-90 degrees), weak flexion, extension, and rotation of shoulder as well as loss of sensation of ...
The axilla (pl.: axillae or axillas; also known as the armpit, underarm or oxter) is the area on the human body directly under the shoulder joint.It includes the axillary space, an anatomical space within the shoulder girdle between the arm and the thoracic cage, bounded superiorly by the imaginary plane between the superior borders of the first rib, clavicle and scapula (above which are ...
The Weaver–Dunn procedure is a type of surgery involved in the treatment of severe separated shoulders developed by James K. Weaver and Harold K. Dunn in the early 1970s. [ 1 ] The procedure is done to replace the coracoclavicular ligaments with the coracoacromial ligament .
Symptoms include pain, swelling, and a decreased ability to move the shoulder. [1] Complications may include axillary nerve or axillary artery injury. [3] The cause is generally a fall onto the arm or direct trauma to the arm. [3] Risk factors include osteoporosis and diabetes. [4] [5] Diagnosis is generally based on X-rays or CT scan. [3]
