Acromio-Clavicular Joint (ACJ) arthritis

Shoulder Steroid (cortisone) Injection London

The Acromio-Clavicular Joint (ACJ) refers to the joint between the end of the collar bone and the acromion, a bony protrusion in the upper, outer part of the shoulder (see white arrow in the figure)

The ACJ commonly undergoes early degeneration, with signs of wear and tear developing after the age of 30.  AC joint arthritis is usually diagnosed with an x-ray which shows narrowing of the joint with small bony outgrowths (osteophytes). The lining of the joint (synovium) becomes inflamed and locally painful.

The joint is very superficial to the skin and as a result the pain associated with ACJ arthritis tends to be well localised and easy to feel when pressing over this area.  It is often associated with tenderness when wearing a backpack or a bra, which can compress the joint.  It is also aggravated when putting on clothes such as a scarf and with overhead activities such as with shoulder press and benchpress exercises, as well as with push ups.

Physiotherapy can help to optimise range of movement and strengthen the structures around the joint to reduce pain but sometimes pain persists and oral pain killers may not provide enough relief.

An injection under ultrasound guidance can help to accurately target the thickened and inflamed joint lining (synovium).  This can reduce inflammation and pain, and alongside avoidance of aggravating activities can result in medium to long-term improvements.
