What is a glenohumeral joint?
Glenohumeral joint is commonly known as the shoulder joint. Humerus or bones of the upper arm usually meet a scoop or shoulder blade to create what is classified as a ball and a joint. This is because the round head of the ball in the shape of the ball fits into a shallow cavity in the shape of a drawer in the shoulder blade known as a glueid cavity. The arrangement allows a large range of movement, but at the same time the joint is not very stable, relying on the surrounding muscles and ties that holds everything together and prevents injury. Lubricating fluid known as synovial fluid can be found in the space between them. Although the part of the joint of the joint is shallow, the glueid cavity has a edge made of fibrous cartilage, which effectively reduces it. The surrounding joint is a capsule that is quite thin and does not fit firmly. This allows the glenohumeral joint to move freely. This helps to provide glenohumeral joint with some stability and protection. The cuff can sometimes be damaged and is a frequent cause of shoulder pain.
A common problem is a frozen arm or adhesive capsulitis. This is where the glenohumeral joint capsules intensify and full of fibrous tissues, making movement limited and painful. The cause is not always easy, although it can be caused by injury to the rotator cuff or a long period of immobility.
The supply of nerve to the capsule and links means that the glenohumeral joint responds to the injury. The surrounding muscles usually respond to the pain by getting into convulsions, preventing joint movement and stopping discomfort. Some of the darkness such as arthritis or infection, glenohumeral joint can occur. This is where the joint lining produces excess fluid that can prove to be swelling between the head of the humerus and the shoulder blade.
Due to many different shoulder movements, joint stability may sometimes be at risk. Therefore, of all the large joints, the shoulder is probably the one that is most often dislocated. Glenohumeral dislocationThe joints occur when the force is suddenly applied to the humerus so that the head of the humerus is down and ruptures the capsules. This can happen during a fall where the arm is stretched.
