Acromion Pain

What is the Acromion?

The acromion is a bony projection of the shoulder blade (scapula). It forms the top outer edge of the shoulder and connects with the collar bone (clavicle) to create the acromioclavicular joint, which is often referred to as the AC joint.

The acromion sits above the humeral head (the top of the upper arm bone) and helps form the subacromial space, which houses important soft tissue structures like the rotator cuff tendons, rotator cuff muscles, and the subacromial bursa (a fluid filled sac that reduces friction).

The acromion also serves as an attachment point for the coracoacromial ligament, which helps to stabilize the shoulder joint. Because of its location, the acromion plays a key role in shoulder movement, especially during overhead activities and external rotation.

What Causes AC Joint Pain?

AC joint pain and acromion discomfort can develop from several underlying issues, often involving irritation or compression within the subacromial space.

Common causes include:

• Repetitive overhead activities (sports, lifting, or work-related motions)
• Rotator cuff tear or degeneration of the rotator cuff muscles
• Inflammation of the subacromial bursa
• Structural variations in the acromion bone that narrow the subacromial space
• Trauma or injury to the shoulder joint or affected arm
• Wear-and-tear changes that lead to chronic pain
• Associated shoulder conditions like adhesive capsulitis (frozen shoulder)

When these issues occur, the acromion can place pressure on surrounding soft tissue, leading to irritation, inflammation, and ongoing discomfort.

Symptoms of Acromion Pain

People experiencing pain related to the acromion often notice symptoms that affect both comfort and function. These may include:

• Pain at the top of the shoulder, especially near the acromioclavicular joint
• Arm pain that may radiate down the affected arm
• Difficulty lifting the arm or performing overhead activities
• Reduced range of motion in the shoulder joint
• Pain during movements like external rotation
• Weakness in the shoulder, particularly involving the teres minor and other rotator cuff muscles
• Tenderness when touching the top outer edge of the shoulder
• Discomfort when lying on the affected side

In many cases, symptoms worsen over time if the underlying issue is not addressed, leading to chronic pain and limited function.

Acromion Pain Diagnosis and Examination

Diagnosing acromion pain begins with a detailed physical examination by an experienced orthopedic surgeon. During this evaluation, your provider will assess your shoulder anatomy, range of motion, and areas of tenderness.

The exam may include:

• Observing how the shoulder moves during specific motions
• Testing strength in the rotator cuff muscles
• Identifying pain patterns associated with shoulder impingement
• Checking for signs of a rotator cuff tear or inflammation

To confirm the diagnosis and better understand the condition, imaging tests such as X-rays or MRI scans may be recommended. These tests can reveal structural issues, inflammation, or damage within the subacromial space, including problems affecting the humeral head or surrounding soft tissue.

How is Shoulder Pain in the AC Joint Treated?

Treatment for ac joint pain and acromion-related discomfort typically begins with nonsurgical treatment options focused on reducing inflammation, improving mobility, and supporting the healing process.

Conservative Treatment Options

• Rest and activity modification to avoid movements that worsen symptoms
• Use of a rolled up towel or support to maintain proper shoulder positioning
• Anti-inflammatory medications to help reduce swelling and discomfort
• Targeted exercises and manual therapy techniques to improve range of motion and function
• Ice and other methods for reducing inflammation and helping relieve pain

These approaches are often highly effective, especially when started early.

When is Surgical Treatment Needed?

If symptoms persist despite conservative care, surgical treatment may be recommended. Surgical intervention may involve reshaping the acromion to create more space in the subacromial area or repairing damaged structures, such as a rotator cuff tear.

The goal of surgery is to relieve pressure, restore normal shoulder mechanics, and provide lasting pain relief. Recovery typically involves a structured healing process aimed at gradually returning to normal physical activity.
