What is Calcific Tendinitis?
Calcific tendinitis (calcific tendinopathy) happens when calcium crystals build up inside a tendon. These deposits irritate surrounding tendons and bursae, causing inflammation, pain, and limited movement.
Approximately 80% of cases occur in the shoulder, most commonly affecting the supraspinatus tendon, followed by the infraspinatus and subscapularis.
Note: It is not caused by dietary calcium intake or taking calcium supplements.
Who Gets It and What Causes It?
- Most common in adults between 40 and 60 years old, with women slightly more affected than men.
- Contributing factors include reduced blood supply to the tendon, natural aging, cellular changes, diabetes, thyroid disorders, and hormonal factors.
Common Symptoms
- Sudden, severe shoulder pain
- Pain when lifting the arm or reaching overhead
- Night pain and difficulty sleeping on the affected side
- Stiffness and reduced range of motion
- Tenderness and localized weakness
Diagnosis and Treatment
Diagnosis
- Physical examination: Checking range of motion, tenderness, and strength.
- X-ray: The primary imaging test for identifying calcium deposits.
- Ultrasound and MRI: Used to assess deposit size, location, and surrounding tendon health.
Treatment
- Rest, activity modification, ice, and NSAIDs.
- Physical therapy for mobility and rotator cuff strength.
- Corticosteroid injections or ultrasound-guided barbotage (lavage).
- Extracorporeal shock wave therapy (ESWT).
- Surgery is needed only in a small percentage of persistent cases.
