Achilles tendon tear or rupture. An Achilles tendon can partially tear or completely tear (rupture) . A tear usually occurs in the tendon about 1.5 in. (3.8 cm) to 2.5 in. (6.4 cm) above where it attaches to the heel bone. Some doctors believe that this area is most likely to tear or rupture because of a limited blood supply.
The Achilles tendon joins the calf muscles to the heel bone and runs down the back of the lower leg. When this tendon is put under excess strain, it can become inflamed. This is Achilles tendinitis. The Achilles tendon is the largest tendon in the body. It can endure great force, but it is still susceptible to injury. Achilles tendinitis, or tendonitis, usually results from microtears that occur in the tendon during strenuous, high impact exercise, such as running. Untreated, the tendon can become torn or ruptured.
