What is a ruptured tendon?
Muscles are attached firmly to bone and connective tissue at one end and generally insert in bones via tendons. Tendons are white fibrous cords that are lined with a loose tissue and which sometimes run through a fibrous tube. Tendons have the ability to glide over bone and through tissues. Muscle contraction is therefore transmitted via the tendons causing intervening joints to move.
In general, tendon rupture occurs in a middle-aged or older man. In the young, muscle usually tears before the attached tendon will tear. But in older people and in those with certain diseases (such as gout and hyperparathyroidism), tendon rupture may result.
