What are AC Separations?
AC (acromioclavicular) separations, also known as shoulder separations or AC joint injuries, occur when the ligaments that connect the collarbone (clavicle) to the shoulder blade (acromion) are damaged or torn. AC separations commonly result from a fall onto the shoulder or a direct blow to the shoulder area.
The severity of an AC separation is classified using a grading system:
- Grade 1: A mild AC separation where the ligaments are stretched but not torn. The collarbone remains in its normal position, and there is minimal deformity or displacement.
- Grade 2: A moderate AC separation where the ligaments are partially torn. This results in some degree of collarbone displacement, leading to a visible bump or deformity at the AC joint.
- Grade 3: A severe AC separation where the ligaments are completely torn. This causes significant displacement of the collarbone, resulting in a noticeable bump or deformity at the AC joint.
Symptoms of AC Separations
- Pain at the top of the shoulder: The pain is usually localized to the AC joint area.
- Swelling and bruising: The shoulder may become swollen and bruised, especially in more severe cases.
- Visible deformity or bump: Grade 2 and 3 AC separations can cause a visible bump or prominence at the AC joint due to collarbone displacement.
- Limited shoulder movement: Shoulder movement may be limited or painful, particularly when trying to lift the arm or perform overhead activities.
Treatment of AC Separations
Treatment for AC separations depends on the severity of the injury, the patient's age and activity level, and the individual's goals and preferences. Treatment options include:
Grade 1 and some Grade 2 AC separations:
These injuries can often be managed non-surgically with conservative measures, such as rest, activity modification, pain management, and physical therapy exercises to improve shoulder strength and mobility.
Severe Grade 2 and Grade 3 AC separations:
These injuries may require surgical intervention, especially for individuals with high activity levels or those who require full shoulder function for their daily activities or sports participation. Surgery typically involves reconstructing or stabilizing the torn ligaments to realign the collarbone and restore shoulder stability.
Rehabilitation for AC Separations
After treatment, rehabilitation is crucial to restore shoulder strength, range of motion, and function. Physical therapy exercises are often prescribed to help with muscle strengthening and joint stability.
It's important to consult with a healthcare professional, such as an orthopedic specialist or a sports medicine physician, for an accurate diagnosis and appropriate treatment plan for an AC separation. They can assess the severity of the injury and guide you through the most suitable treatment options based on your specific circumstances.
If you suspect an AC separation or have any concerns about your shoulder health, it is best to consult with a qualified healthcare provider for an accurate diagnosis and personalized treatment.
