Rotator Cuff Calcific Tendinitis

Calcific tendinitis of the rotator cuff occurs when calcium deposits form within the tendon, most commonly the supraspinatus. These deposits can cause acute severe pain during the resorptive phase or chronic aching pain during the formative phase. It affects up to 20% of adults with shoulder pain.

Typical Recovery Time

Acute phase resolves in days to weeks; chronic cases may take 3–6 months

Symptoms

•Sudden severe shoulder pain (acute phase)
•Difficulty moving the arm in any direction
•Pain at rest and at night
•Localized tenderness
•Reduced range of motion

Common Causes

•Calcium crystal deposition of unknown origin
•Repetitive microtrauma
•Metabolic factors (thyroid disease, diabetes)
•Tendon hypoxia
•Age 30–50 most commonly affected

Treatment Options

1NSAIDs and ice during acute phase

2Ultrasound-guided needling and lavage (barbotage)

3Corticosteroid injection for symptom control

4Shockwave therapy

5Arthroscopic removal for refractory cases

When to See a Doctor

See a provider promptly if pain is severe and sudden — calcific tendinitis in the acute resorptive phase can mimic a septic joint and needs evaluation.

Frequently Asked Questions

What is rotator cuff calcific tendinitis?

Calcific tendinitis is a condition where calcium deposits form within the rotator cuff tendons. This can cause sudden or severe shoulder pain. The condition often goes through phases of buildup and breakdown.

What causes calcific tendinitis?

The exact cause is not fully understood, but it may be related to tendon degeneration or changes in blood flow. It often occurs without a specific injury. Middle-aged adults are most commonly affected.

What are the symptoms?

Symptoms include sharp shoulder pain, especially with movement or at night. Some patients have limited motion and difficulty lifting the arm. Pain can come on suddenly during the resorptive phase.

How is it treated?

Treatment includes anti-inflammatory medications, physical therapy, and sometimes ultrasound-guided procedures to break up the calcium. Injections may help reduce pain. Most cases improve without surgery.

How long does recovery take?

Recovery varies depending on the phase of the condition. Some people improve over weeks, while others take several months. Symptoms often resolve as the calcium is reabsorbed.
