THE MECHANISM OF TOTAL DISLOCATION OF THE TALUS
Baldo Leitner M.D.1
1 Unfallkrankenhaus, Wien
Total dislocation of the talus results either from excessive supination or from excessive pronation; accordingly the dislocated talus lies either laterally or medially. A first-degree supination injury results in medial subtalar dislocation; a second-degree supination injury results in medial subtalar dislocation with talocrural subluxation; and a third-degree supination injury results in total lateral dislocation of the talus.
A first-degree pronation injury results in lateral subtalar dislocation; a second-degree pronation injury results in lateral subtalar dislocation, together with talocrural subluxation; and a third-degree pronation injury results in total medial dislocation of the talus.
