Clinical Significance The Achilles tendon is the thickest tendon in the body and rupturing this structure takes a tremendous amount of force.  Powerful plantarflexion while jumping is the most common mechanism and most commonly occurs in inflammed or chronically stressed tendons.

History – I am a bit of a mythology geek and I love this eponym.  The Achilles tendon was named after the famous Greek warrior, Achilles, who was the hero of the Trojan War for killing Prince Hector, son of King Priam of Troy.  This is a major part of Homer’s Illiad. 

I digress…..

The reason for this eponym is that Achilles’ mother is Thetis, an immortal sea nymph, who could not bear to see her child injured or killed.  To remedy this, she dipped him in the River Styx to make him invulnerable.  Since he was mortal, she couldn’t just drop him in, so she held him by the heel.  The spot on his heel that was held by Thetis was unprotected and ultimately would be his “Achilles Heel” (get it) when an arrow shot by Paris, brother of Hector, pierced this spot and killed him.
