What are the common causes of acromioclavicular pain?
Acromioclavicular pain describes pain felt on or around acromioclavicular (AC) joint, a place on the front of the shoulder, where the collar cube articulates with the scoop - that is, where the key is the joint with the shoulder blade. Although there is no large amount of movement between the two bones, some gliding and turning the bones against each other is essential to lift the arms over their heads. As with any movable joint, the joint can cause damage, such as dislocation caused by a sharp trauma or an inflammatory condition caused by frequent and recurring shoulders over time. Common causes of acromioclavicular pain include dislocation of alternating joint or fracture of bones in the joint, damage to the joints surrounding the joint, joint inflammation due to excessive use or arthritis, which is the condition characterized by carrying joint cartilage.
The bones of the acromioclavicular joint include collarbones or collarbone, narrow bone several inches to length that laterally bridgee upper chest and process of acromions of shoulder blades or shoulder blades. It is a curved piece of bone that projected from the back of the blade at an angle, pointing towards the shoulder before turning forward across the upper part of the shoulder blade. The acromion process sits directly above the glenohumeral or shoulder joint, where the bones of the arm meet the shoulder blade; AC The joint is located between the inner aspect of the acromion and the outer end of the collarbone on the front of the shoulder. Directly between the bones is a layer of fibrocartilage for padding, while the neighboring ends of the bones are covered with ligaments exceeding the joint.
acromioclavicular pain can suddenly be raised as a sudden injury or over time due to chronic injury or disease. Athletes that play contact sports may be particularly prone to traumatic AC joint injuries that can be caused by collision or fall. One of the common damage of this place is the dislocation of the collarbone from the acromion process in which the collar clovor is displaced from its artirounding surface on acromion. When this happens, acromioclavicular (AC) ligaments that exceed the joint and coroclavicular (CC) ligament that connects to the acromion process into the nearby Coracoid process. In serious cases, muscles such as deltooid and trapezoids that connect to these bones can tear or maintain other damage.
While sudden trauma can cause serious acromioclavicular pain, less traumatic joint injuries can become quite painful. Individuals who often lift weights, and athletes who repeatedly rise in the air, such as basketball and volleyball players, are particularly susceptible to the pain resulting from overuse of injuries. The common form of this injury is the shsyndrome osulder, in which the muscle tendon running under the AC joint and over the upper part of the shoulder becomes inflamed, swells and three on the underside of the acromion process. This results in not only the painful wear of the tendon, but in the development of bone spots, bony growth of the European ChampionshipZi bones and tendons that narrow the space and increase the friction between the tendon and the bone. Such pain may be difficult to eliminate without avoiding movements that lead to tendon impact in the first place.
Chronic diseases are another common cause of acromioclavicular pain, with AC arthritis predominant. Arthritis is brought over time and with wear and is more common in persons who have previously suffered joint injuries. This disease involves gradual degeneration of tissues inside the joint, namely cartilage protecting bones from walking against each other. As joint pain caused by other conditions, the pain of AC joint arthritis feels like pain directly at the point of the joint that burns when the arm moves into the shoulder joint, pain that can be alleviated by the use of ice and use of non -steroidal anti -inflammatory (NSAIDs) drugs. Unlike other sources of acromioclavicular pain, however, arthritis pain can also be alleviated by the light of the shoulder joint.
