Acromioclavicular joint arthritis

Acromioclavicular joint arthritis is a degenerative condition affecting the acromioclavicular (AC) joint, which is located at the top of the shoulder, where the acromion of the scapula meets the clavicle.

This condition is characterized by the breakdown and eventual loss of cartilage within the joint, leading to pain, inflammation, and decreased range of motion.

The AC joint is crucial for shoulder movement, and its deterioration can significantly impact the ability to perform overhead activities and movements that require lifting the arm.

Common symptoms include localized pain at the top of the shoulder, swelling, and a visible bump over the joint.

In advanced cases, there may be a grinding sensation or popping sound during shoulder movement.

Risk factors for developing acromioclavicular joint arthritis include age, previous shoulder injuries, and repetitive stress from activities such as weightlifting or overhead sports.

Diagnosis typically involves a physical examination and imaging studies, such as X-rays, to assess the extent of joint degeneration.

Management of this condition may include physical therapy, nonsteroidal anti-inflammatory drugs (NSAIDs), corticosteroid injections, and in severe cases, surgical intervention to remove damaged portions of the joint or to reconstruct the joint to restore function and alleviate pain.

Early diagnosis and intervention can help manage symptoms and maintain shoulder functionality.
