What Causes AC Pain?
Many injuries and degenerative conditions contribute to acromion shoulder pain, including:
Shoulder Injuries
Injuries are one of the most prevalent causes of acromion pain.
When you fall, either onto your shoulder or an outstretched arm, you risk spraining the ligaments that connect your acromion to the other bones in your shoulder, including the coracoclavicular ligaments.
Your discomfort could also stem from collarbone fractures or dislocations.
Impingement Syndrome
Shoulder impingement syndrome occurs when your acromion rubs on your rotator cuff, including the tendon and bursa in the subacromial space.
Subacromial impingement causes inflammation in your shoulder, restricting motion and causing pain and stiffness.
Osteoarthritis
You can also develop osteoarthritis in your AC joint as the cartilage that covers, protects, and lubricates the joints wears away.
Day-to-day activities and aging lead to the breakdown of the cartilage which causes osteoarthritis to develop.
Rotator Cuff Tears
Problems with the AC joint can also increase your risk of a torn rotator cuff.
Repetitive movements that press the acromion against the rotator cuff tendons can weaken and damage the tissue, leading to severe pain and reduced mobility.
How Is Shoulder Pain in the AC Joint Treated?
The shoulder specialists at OrthoNeuro begin with a comprehensive exam to identify the specific condition causing your symptoms.
They will feel your AC joint for tenderness and check for signs of inflammation or deformity.
Your doctor may also gently lift or rotate your arm, or ask you to do so yourself, so they can see how your discomfort affects your mobility.
