WHAT KINDS OF PROBLEMS OCCUR AT THE AC JOINT?
The most common problems that occur at the AC joint are arthritis, fractures and “separations.” Arthritis is a condition characterized by loss of cartilage in the joint. Like arthritis at other joints in the body, it is characterized by pain and swelling, especially with activity. Over time, the joint can wear out, leading to swelling and formation of spurs around the joint. These spurs are a symptom of the arthritis and not the primary cause of the pain. Motions which aggravate arthritis at the AC joint include reaching across the body toward the other arm. AC joint arthritis is common in weight lifters, especially with the bench press, and to a lesser extent military press. AC joint arthritis may also be present when there are rotator cuff problems.
