PERITENDINITIS AND TENOSYNOVITIS - A REVIEW

The muscle-tendon unit may be inflamed in the area of the tendon sheath (tenosynovitis) or outside of it, in the paratenon and the muscle-tendon junction (peritendinitis). Both variants resemble each other with regard to their clinical picture, but the location is different. Although these diseases are often seen at physicians' offices and they are expensive, in economic terms, due to lost workdays, little is known of their occurrence rates, pathogenesis, or etiology. Yet, most investigators think that overexertion of the muscle-tendon unit is the main cause of morbidity. So far, this hypothesis has not been formally tested.
