The Achilles tendon is the tendonous extension of three muscles in the lower leg: gastrocnemius, soleus, and plantaris. In humans, the tendon passes behind the ankle. It is the thickest and strongest tendon in the body. It is about 15 cm long, and begins near the middle of the leg, but receives fleshy fibers on its anterior surface, almost to its lower end. Gradually becoming contracted below, it is inserted into the middle part of the posterior surface of the calcaneus, a bursa being interposed between the tendon and the upper part of this surface. The tendon spreads out somewhat at its lower end, so that its narrowest part is about 4 cm. above its insertion. It is covered by the fascia and the integument, and stands out prominently behind the bone; the gap is filled up with areolar and adipose tissue. Along its lateral side, but superficial to it, is the small saphenous vein. The achilles' muscle reflex tests the integrity of the S1 spinal root. Grays Fig. ...

The oldest-known written record of the tendon being named for Achilles is in 1693 by the Flemish/Dutch anatomist Philip Verheyen. In his widely used text Corporis Humani Anatomia, Chapter XV, page 328, he described the tendon's location and said that it was commonly called "the cord of Achilles" ("quae vulgo dicitur chorda Achillis"). The Wrath of Achilles, by François-Léon Benouville (1821–1859) (Musée Fabre) In Greek mythology, Achilles (also Akhilleus or Achilleus) (Ancient Greek: ) was a hero of the Trojan War, the central character and greatest warrior of Homers Iliad, which takes for its theme, not the War...

The name Achilles' heel comes from Greek mythology. His mother, the goddess Thetis, received a prophecy of her son's death. In order to protect him, she dipped him into the River Styx, which protected his entire body from harm. However, in order to dip him into the river, she needed to grab onto his heel. During the Trojan War Achilles was struck on his unprotected heel by a poisoned arrow, which killed him.

Role in disease

Achilles tendonitis is inflammation of the tendon, generally due to overuse of the affected limb or as part of a strain injury. More common is Achilles tendinosis, a degenerative condition with inflammation of the tendon, often accompanied by pain and swelling of the surrounding tissue and paratendon. Maffulli et al. suggested that the clinical label of tendinopathy should be given to the combination of tendon pain, swelling and impaired performance. Achilles tendon rupture is a partial or complete break in the tendon; it requires immobilisation or surgery.

Treatment of Achilles tendon damage

Initial treatment of damage to the tendon is generally nonoperative. Orthotics can produce early relief to the tendon by the correction of malalignments, non-steroidal anti-inflammatory drugs (NSAIDs) are generally to be avoided as they make the more-common tendinopathy (degenerative) injuries worse[citation needed]; though they may very occasionally be indicated for the rarer tendinitis (inflammatory) injuries. Physiotherapy by eccentric calf stretching under resistance is commonly recommended, usually in conjunction with podiatric insoles or heel cushioning. According to reports by Hakan Alfredson, M.D., and associates of clinical trials in Sweden, the pain in Achilles tendinopathy arises from the nerves associated with neovascularization and can be effectively treated with 1-4 small injections of a sclerosant. In a cross-over trial, 19 of 20 of his patients were successfully treated with this sclerotherapy. Orthotics is the medical field concerned with the application and manufacture of orthoses, devices which support or correct the function of a limb or the torso. ... Non-steroidal anti-inflammatory drugs, usually abbreviated to NSAIDs, are drugs with analgesic, antipyretic and anti-inflammatory effects - they reduce pain, fever and inflammation. ...

Where tendon rupture is concerned, there are three main types of treatment: the open and the percutaneous operative methods, and nonoperative approaches.

Achilles tendon damage in popular culture

Severance of the Achilles tendon is considered by many a particularly unpleasant injury. This has led authors to use it for shock value. Achilles tendons are severed in the movies Pet Sematary (1989), Sympathy for Mr. Vengeance (2002), Kill Bill (2003), House of Wax (2005), Hostel (2006), and Saw 3 (2006) . In the Gor novels, severing Achilles tendons is a punishment for slaves who try to flee.

Ironically, during the filming of Troy (2004), Brad Pitt injured his achilles tendon and was unable to perform during this period. Troy is a movie that was released on May 14, 2004 about the Trojan War, which is described in Homers Iliad and other Greek myths as having taken place in Anatolia (modern Turkey) around the 13th or 12th century BC; however, the plot differs greatly from Homer (see deviations...
