THE ASTRAGALUS: A Case of Dislocation, Excision, and Replacement. An Attempt to Demonstrate the Circulation in this Bone.

Function may be hoped for after removal of the astragalus with its cartilage intact and replacement of this bone.

We believe that in all severe dislocations of the astragalus the blood supply of the bone is interrupted,-perhaps temporarily destroyed.

There is no main nutrient artery to this bone. It is supplied by numerous small blood vessels.

We are of the opinion that the vessels supplying this bone cannot be stretched to the degree necessary for dislocation without rupture. This confirms the statements made by Nelaton.

We believe that in severe dislocations of the astragalus this bone may be replaced in normal position and a good functionating foot may be hoped for.
