To compensate for the shallow shoulder socket, the joint has a cuff of cartilage called a labrum that forms a cup for the end of the arm bone. When a patient sustains a shoulder injury, it is possible that the patient has a labral tear. The labrum also becomes more brittle with age and can fray and tear as part of the aging process.
The glenohumeral joint is another name for your shoulder joint. This ball-and-socket joint is vulnerable to osteoarthritis due to its frequent use. It can become worn down with age, causing pain and mobility issues.
According to the Cleveland Clinic, people who frequently swim are at risk of shoulder issues from overuse. In fact, 65% of swimmers experience a shoulder injury during their lifetime, but they are not the only ones.
Shoulder pain can range from mild to severe and can come on suddenly or build up over time. Shoulder pain causes include fractures, tissue inflammation or tears, joint or ligament instability, and arthritis.
Arthritis in the AC joint is a most common cause of shoulder pain in adults. Arthritis here usually develops when the smooth cartilage between your scapula and collar bone wears down, becoming thin and rough. This can cause pain and inflammation in the joint when the end of your bones rub against each other.
