Cause of calcific tendonitis

Calcific tendonitis is a comparatively common disease with an incidence between 2.7 and 7.5% and minority of cases are symptomatic.

The Etiology of the calcific tendonitis is still unclear.

Possible Causes of calcific tendonitis :

- Hypovasculariation, but has been removed from both poorly and well-vascularized tissues.
- Compression,
- Metabolic factors,
- Mesodermal defects,
- Local degenerative and proliferative changes

Unlikely Causes of calcific tendonitis :

- Infection and trauma,
- Blood or urine chemistry,
- Calcific tendonitis occurs in 2.5%–7.5% of healthy shoulders in adults, and 39% to 62% of those being seen in medical centers for shoulder pain.

Calcified tendonitis is more commonly seen in women (70% of cases) and most frequently during the 5th decade of life, but has been seen in a 3 year-old and a 72 year-old patient...

Right shoulder is more frequently affected by calcific tendonitis but there is no evidence to support predisposing factors.
