Anatomy of the AC Joint

The acromioclavicular (AC) joint is the point where the clavicle (collarbone) meets the acromion (the highest part of the shoulder blade). This joint is secured by multiple ligaments and cushioned by cartilage at the ends of each bone. Injuries to the AC joint are common shoulder conditions, usually resulting from a hard fall or blunt force.

Dr. Khaleel, Senior Consultant Arthroscopic Shoulder and Sports Surgeon, Kims Alshifa, Perintalmanna, Kerala, India, specializes in treating AC joint injuries and can help alleviate pain, guiding patients towards an active, healthy lifestyle.

Causes of AC Joint Injuries

AC joint injuries often result from a direct impact to the top of the shoulder. This impact can range in severity from a mild sprain to a complete shoulder separation.

The injuries are classified into grades:

Grade 1: Mild sprain

Grade 6: Severe, complete disruption resulting in a total AC joint separation

Symptoms of an AC Joint Injury

The primary symptom of an AC joint injury is pain upon palpation of the joint. This pain can range from mild tenderness to sharp, intense discomfort, typically felt at the top of the shoulder.

Other symptoms may include:

• Bruising
• Swelling
• Visible deformity
• Popping sensation (in higher-grade injuries)

Diagnosing an AC Joint Injury

Diagnosis involves a thorough physical examination of the shoulder and a series of X-rays to confirm the diagnosis and rule out fractures. Additionally, an MRI scan may be performed to determine the injury's grade and assess ligament damage, allowing for an effective treatment plan.
