LOWER EXTREMITY.
Gunshot Fracture of the Ankle.

The course of the bullet was anteroposterior, striking the fibula from behind with a velocity of long range, and causing some slight fragmentation without displacement of the fragments.

The joint architecture is slightly disturbed. The joint mortice is a bit widened by the external deflection of the external malleolus, which permits a slight outward rotation of the astragalus.

As the dangers of infection are usually escaped, the treatment is that for Pott’s fracture.
