Calcific Tendonitis


Calcific tendonitis is a painful condition affecting the rotator cuff tendons of the shoulder.

The rotator cuff is a group of four tendons around the shoulder which are responsible for movement and stability of the shoulder joint.

Calcium deposits of 1-2cm form in areas of tendon wear and tear. It causes tissue irritation and inflammation. It most commonly forms in the supraspinatus tendon.

This condition most commonly affects women and people in 30-60 year age group. Diabetics are also more commonly affected.



The exact cause is not known in many cases. The condition is often NOT related to a specific traumatic event. The incidence is higher in diabetics.

Symptoms and Signs

Diagnosis is based on patient symptoms, examination findings and scan results.


This is typically quite severe when the calcium is being resorbed by the body. It is worse with shoulder movement and may be quite painful at night when sleeping. The pain may radiate down the arm.

Clicking / Catching

This may occur with shoulder movement. Irritated tendons may occasionally click or snap with arm use.

Reduced movement

Some reduced movement may occur.


Some weakness may occur.



This will reveal an area of calcification.

Ultrasound and MRI

This will reveal the exact location of the calcium deposit within the rotator cuff tendon and if there is an associated tendon tear.

Non-surgical treatment

Treatment depends on length and severity of symptoms. Non-surgical measures are tried as first line treatment.

Activity Modification

Avoid repetitive shoulder use and sleeping on the affected side.

Pain Killers / Anti-Inflammatory Medications

Anti-Inflammatory medications such as Nurofen help settle the inflammation and pain down.

Heat or Ice

Heat or ice may be used to settle the inflammation down.


This is aimed at maintaining and restoring shoulder movement and strength.

Steroid Injection

This is used to provide a local anti-inflammatory effect to provide pain relief.

Needle Aspiration and Lavage

This is performed by a radiologist. Occasionally, large painful calcium deposits may be broken down with a needle, sucked out and washed out to reduce the calcium load and provide relief.
