Because his heel was never immersed, it remained his one area of vulnerability. After the fall of Troy, Achilles met his demise when he was shot in the heel by Paris, whose arrow was guided by the Greek god Apollo.

Three basic mechanisms of injury have been described: (1) dorsiflexion violence against the maximally plantarflexed foot, typically occurring in a fall from a height; (2) powerful contraction of the triceps surae muscle with simultaneous extension of the knee such as when a person is about to sprint in a race; (3) a direct blunt blow to the hindfoot.\n                    <jats:sup>1 , 2 , 8<\/jats:sup>\n                  <\/jats:p>\n                  <jats:p>We are describing a case of avulsion of the calcaneal tuberosity due to direct penetrating trauma from a gunshot wound, a mechanism not previously reported.<\/jats:p>","DOI":"10.1177\/107110078900900411","type":"journal-article","created":{"date-parts":[[2013,3,3]],"date-time":"2013-03-03T03:24:58Z","timestamp":1362281098000},"page":"204-206","source":"Crossref","is-referenced-by-count":16,"title":["The Heel of Achilles: Calcaneal Avulsion Fracture from a Gunshot Wound"],"prefix":"10.1177","volume":"9","author":[{"given":"Daniel E.","family":"Cooper","sequence":"first","affiliation":[{"name":"Department of Orthopaedics, University of Texas Health Science Center at San Antonio"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"James D.","family":"Heckman","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics, University of Texas Health Science Center at San Antonio"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[1989,2,1]]},"reference":[{"key":"bibr1-107110078900900411","first-page":"258","volume":"117","author":"Arner O.","year":"1959","journal-title":"Acta.
