AC Arthritis

Understanding AC Arthritis

AC arthritis, or acromioclavicular arthritis, is a condition that affects the acromioclavicular joint, which is located at the top of the shoulder where the collarbone (clavicle) meets the highest point of the shoulder blade (acromion). This condition is characterized by the degeneration of the cartilage in the joint, leading to inflammation and pain.

Causes and Symptoms of AC Arthritis

AC arthritis is most commonly caused by the natural aging process. Over time, the cartilage in the AC joint can wear away, leading to bone-on-bone contact and resulting in inflammation and pain. Other causes can include injury to the joint, such as a dislocation or fracture, and overuse from activities that involve heavy lifting or overhead movements.

Symptoms of AC arthritis can include pain and tenderness over the front of the shoulder, pain that worsens with activities such as lifting or reaching overhead, and a grinding or popping sensation in the shoulder.

Diagnosis and Treatment

Diagnosis of AC arthritis typically involves a physical examination and a review of the patient’s medical history. The doctor may perform specific movements to test the range of motion in the shoulder and to identify any areas of pain or discomfort. Imaging tests, such as X-rays or an MRI, may also be used to confirm the diagnosis and assess the severity of the condition.

Treatment for AC arthritis often involves conservative measures, such as rest, physical therapy, and non-steroidal anti-inflammatory drugs (NSAIDs) to manage pain and inflammation. If these measures are not effective, more invasive treatments, such as corticosteroid injections or surgery, may be considered.

Prevention and Prognosis

While it is not always possible to prevent AC arthritis, there are measures that can be taken to reduce the risk and manage symptoms. These include maintaining a healthy weight, staying active, and performing exercises to strengthen the shoulder muscles and maintain joint flexibility.

The prognosis for AC arthritis varies depending on the severity of the condition and the effectiveness of treatment. With appropriate management, most individuals with AC arthritis are able to maintain a good quality of life and continue their normal activities.

In conclusion, AC arthritis is a common condition that can cause significant shoulder pain and disability. However, with early diagnosis and appropriate treatment, most individuals with this condition are able to manage their symptoms and maintain their quality of life.
