AC Joint Dislocation

An AC joint dislocation occurs when the joint at the top of the shoulder where the acromion (a bony projection of the scapula) meets the clavicle (collarbone) becomes disrupted. This can happen due to a fall directly onto the shoulder or an outstretched arm, such as during a sports injury or accident. The severity of the dislocation can vary from a mild displacement to a complete separation of the joint.

Dr. Ishan Shevate would likely provide a thorough assessment of the injury, including imaging studies such as X-rays or MRI scans, to determine the best course of treatment for the patient’s specific condition. They would also provide guidance on rehabilitation and preventive measures to avoid future injuries.

The Acromioclavicular joint is located at the top of the shoulder, where the collarbone (clavicle) meets the highest point of the shoulder blade (acromion). A dislocation of this joint typically occurs due to a sudden impact or fall directly onto the shoulder. This injury is common among athletes, especially those involved in contact sports like football, rugby, or hockey.

Symptoms of an AC joint dislocation may include:

Pain at the top of the shoulder, particularly with movement or pressure.
Swelling and tenderness over the AC joint.
Limited range of motion in the shoulder.
A visible bump or deformity above the shoulder, indicating the displaced joint.

Treatment for an AC joint dislocation depends on the severity of the injury. In mild cases, rest, ice, and anti-inflammatory medication may be sufficient to reduce pain and swelling. Physical therapy exercises can help restore strength and range of motion in the shoulder.

For more severe cases or complete dislocations, a doctor may recommend:

Immobilization with a sling or brace to allow the joint to heal.
Closed reduction, a procedure to manually realign the joint.
Surgery to stabilize the joint, particularly if there is significant ligament damage or repeated dislocations.

FAQ...

What is an AC joint dislocation ?

An AC joint dislocation occurs when the collarbone (clavicle) separates from the acromion, which is part of the shoulder blade (scapula).

What causes AC joint dislocation ?

AC joint dislocations are commonly caused by a direct blow to the shoulder, such as during a fall onto the shoulder or an impact during sports.

What are the symptoms of AC joint dislocation ?

Symptoms may include pain, swelling, tenderness, deformity or prominence of the collarbone, limited shoulder movement, and a popping or grinding sensation with shoulder movement.

How is AC joint dislocation diagnosed ?

Diagnosis is typically based on a physical examination, medical history, and imaging tests such as X-rays or MRI scans to assess the extent of the injury and rule out other potential shoulder problems.

What are the different types of AC joint dislocation ?

AC joint dislocations are classified based on the severity of the injury, ranging from mild sprains (grade 1) to complete separations of the joint (grade 3, 4, 5, or 6), with higher grades indicating more severe displacement.

How is AC joint dislocation treated ?

Treatment may include rest, ice, pain medications, immobilization with a sling, physical therapy, and in severe cases, surgical intervention to repair or reconstruct the damaged ligaments and stabilize the joint.

What is the recovery time for AC joint dislocation ?

Recovery time varies depending on the severity of the injury and individual factors, but most people can expect to gradually resume normal activities within a few weeks to several months with appropriate treatment and rehabilitation.

Are there any complications associated with AC joint dislocation ?

Complications may include chronic pain, instability or weakness in the shoulder, arthritis of the AC joint, and recurrent dislocations if the injury is not properly treated or if there is underlying joint laxity.

Can AC joint dislocation be prevented ?

While it may not be possible to prevent all AC joint dislocations, wearing appropriate protective gear during sports and activities that carry a risk of shoulder injury can help reduce the risk.

When should I seek medical attention for AC joint dislocation ?

You should seek medical attention if you experience severe pain, swelling, deformity, or loss of shoulder function after a fall or injury to the shoulder, as prompt treatment can help prevent further damage and promote faster recovery.
