Tendinitis - Overview

Alternative Names

Calcific tendinitis; Bicipital tendinitis

Definition of Tendinitis:

Tendinitis is inflammation, irritation, and swelling of a tendon, which is the fibrous structure that joins muscle to bone. In many cases, tendinosis (tendon degeneration) is also present.

Causes, incidence, and risk factors:

Tendinitis can occur as a result of injury, overuse, or with aging as the tendon loses elasticity. It can also be seen in persons with body-wide (systemic) diseases such as rheumatoid arthritis or diabetes.

Tendinitis can occur in any tendon, but some commonly affected sites include the:

Elbow
Heel (Achilles tendonitis)
Shoulder
Wrist
