Aviator’s Astragalus

 

Other Known AliasesNone

Definition – Any fracture dislocation of the talus.

Clinical Significance None.  This is an antiquated term for talar injuries

History – First coined in 1919 by Henry Graeme Anderson, who was a consulting surgeon for the Royal Flying Corps during World War I.  He described 18 cases of fracture and dislocation of the talus in pilots between 1914-1919.  During the early history of flight, planes did not reach lethal speeds and when they crashed, the rudder bar (which was controlled by the pilot’s feet) would get driven up into the instep of the foot just anterior to the calcaneous.
