The acromioclavicular (AC) joint is the small joint located at the top of the shoulder, where the collarbone (clavicle) meets the highest point of the shoulder blade (acromion).

​

Clinical Symptoms

AC joint pain is localized directly to the top of the shoulder. It is typically provoked by reaching across the body (cross-body adduction), lifting heavy objects, performing push-ups or bench presses, or sleeping directly on the shoulder point.

​

Causes & Injection Solutions

AC joint pain usually stems from localized osteoarthritis, prior acromioclavicular joint sprains, or repeated heavy compression loading.

 

• Targeted Injections: Because the AC joint is very small and superficial, precise placement is essential. We perform ultrasound-guided AC joint injections utilizing low-dose corticosteroids or hyaluronic acid to calm joint inflammation and provide durable localized symptomatic relief.
