50 @entity1 following talar @entity174 , 3 and 4 during the years 1972-1993, could be analysed retrospectively. Evaluated factors effecting posttraumatic avascular @entity39 of the body of the talus are: type of @entity174 , age of the @entity1 , additional @entity174 of the medial malleolus and time of non weight bearing. The Hawkins sign is reliable to show vitality in the body of the talus. We could see @entity455 in 51% of all Marti 3 @entity174 and in 100% of all Marti 4 @entity174 . @entity1 with a concomitant @entity174 of the inner malleolus showed positive influence on the blood supply of the talus. In this case the ligamentum deltoideum and the ramus deltoideus of the arteria tibialis posterior remained intact. In addition to this the prognosis was better in young @entity1 . A long period of non weight bearing could not preserve vitality of the talus. Necrosis of the talus did only appear in 34% of the Marti 3 and in 51% of the Marti 4 @entity174 . This means that early anatomic reconstruction of the talus is necessary. Primary arthrodesis of the ankle joint and talectomie are not up to date.
