The arterial supply of the talus. A study on the relationship to experimental talar fractures.

After filling the arteries of the talus with contrast medium, fractures of the neck were produced to study the effect on these vessels. It was found that the ascending branches from the main arteries, arteria canalis tarsi and arteria sinus tarsi, were ruptured in all cases. The vessels in the fracture area were all sharply cut off. Without fracture displacement the surrounding arteries were remarkably intact, whereas with displacement these became affected by varying degrees of disruption. The vessels in the bone adjacent to the fracture remained intact.
