Acromioclavicular osteoarthritis

The acromioclavicular (AC) joint is a joint in the shoulder composed of the lateral part of the shoulder bone (acromion) and the clavicle. This joint is important for shoulder mobility and stability and can be affected by injuries such as acromioclavicular subluxation or osteoarthritis.

Causes of Acromioclavicular Osteoarthritis
The most common causes of acromioclavicular osteoarthritis include:

• Wear and tear: Osteoarthritis can be caused by normal wear and tear over time, especially after age 50.
• Previous injuries: Previous injuries, such as shoulder dislocations, can increase the risk of acromioclavicular osteoarthritis.
• Repetitive overload: Repetitive overload or overuse of the shoulder can cause injury to the acromioclavicular joint and increase the risk of arthritis.
• Genetics: Some studies suggest that acromioclavicular arthritis may be inherited.
• Systemic Diseases: Systemic diseases, such as osteoporosis, can increase the risk of arthritis in all joints, including the acromioclavicular joint.

Diagnosis of Acromioclavicular Osteoarthritis
The diagnosis of acromioclavicular osteoarthritis is made through a combination of a clinical evaluation, a complete medical history, and various imaging tests. These may include X-rays, ultrasound, and MRI. The doctor may also perform a physical evaluation and movement tests to determine the severity of the condition and identify other factors that may be contributing to the symptoms.

Treatment of Acromioclavicular Osteoarthritis
Treatment for acromioclavicular (AC) osteoarthritis depends on the severity of the symptoms and how they are affecting the patient's quality of life. Some treatments include:

• Physical Therapy: Muscle strengthening and stretching to relieve pressure on the AC joint.
• Lifestyle Modifications: Avoiding activities that cause pain and resting the AC joint.
• Analgesics and nonsteroidal anti-inflammatory drugs (NSAIDs): to reduce pain and inflammation.
• Ultrasound-guided corticosteroid injections: to reduce inflammation and pain, improving shoulder function. Ultrasound guidance is especially useful as the joint is small and difficult to access.
• Ice therapy: applying ice to the affected area to reduce inflammation and pain.
• Surgery: in severe cases, a surgical procedure may be necessary to repair or reconstruct the AC joint.

It is important to note that treatment for AC osteoarthritis should be individualized and based on the evaluation of a healthcare professional.
