Acromio-Clavicular (AC) joint sprain, subluxation, and dislocation are common injuries that can occur in the joint at the top of the shoulder, where the collarbone (clavicle) meets the shoulder blade (scapula). The AC joint is responsible for providing stability and range of motion to the shoulder, and when it is injured, it can cause pain and discomfort.

Causes of AC Joint Sprain, Subluxation, and Dislocation:

AC joint sprain, subluxation, and dislocation are typically caused by a traumatic injury, such as a fall onto the shoulder or a direct blow to the joint. These injuries can cause the ligaments that hold the joint together to stretch or tear, leading to a range of symptoms.

Symptoms of AC Joint Sprain, Subluxation, and Dislocation:

The symptoms of AC joint sprain, subluxation, and dislocation can vary depending on the severity of the injury, but they typically include:

• Pain and tenderness in the shoulder, particularly when moving the arm or shoulder
• Swelling and bruising around the shoulder joint
• A visible bump or deformity at the top of the shoulder
• Limited range of motion in the shoulder
• A popping or clicking sensation in the shoulder joint

Diagnosis of AC Joint Sprain, Subluxation, and Dislocation:

I can diagnose AC joint sprain, subluxation, and dislocation through a physical exam and imaging tests such as X-rays, MRI or ultrasound. During a physical exam, I will check for tenderness, range of motion, and any visible swelling or deformity in the shoulder. Imaging tests can confirm the diagnosis and determine the extent of the injury.

Treatment of AC Joint Sprain, Subluxation, and Dislocation:

Treatment for AC joint sprain, subluxation, and dislocation depends on the severity of the injury. Mild cases may be treated with rest, ice, and pain medication. More severe cases may require a combination of treatments, such as:

• Physiotherapy: exercises to help maintain range of motion and strength in the shoulder
• Immobilisation: wearing a sling or brace to immobilise the shoulder and allow the ligaments to heal
• Steroid injections: injections of anti-inflammatory medication to reduce pain and inflammation
• Surgery: if other treatments do not provide relief, surgery may be necessary to repair or reconstruct the damaged ligaments.

Recovery from AC Joint Sprain, Subluxation, and Dislocation:

Recovery from AC joint sprain, subluxation, and dislocation depends on the severity of the injury and the type of treatment received. Mild cases may resolve with rest and ice, while more severe cases may require surgery and rehabilitation. Most patients are able to manage their symptoms and return to their normal activities with appropriate treatment.

In conclusion, AC joint sprain, subluxation, and dislocation are common injuries that can cause pain and discomfort in the shoulder joint. If you suspect you have one of these injuries, it is important to seek medical attention promptly to receive an accurate diagnosis and appropriate treatment. With proper treatment and rehabilitation, most people are able to manage their symptoms and return to their normal activities.
