Rifle—Plate 36.
UPPER EXTREMITY.
Gunshot Fracture of the Ulna.
The course of the bullet was anteroposterior through the ulna a little above the middle of the forearm, and fairly through the long axis.
This is a bone effect much similar to those shown in plates [28], [29], and [31], except that this condition is due to the impact of a missile, with a still higher velocity of shorter range, imparting its energy to small fragments of bone, which added their momentum to the destructive force of the projectile.
No large fragments were carried along with the missile to cause any more destruction of tissue in exit than in entrance, so that the skin wounds, under these conditions, are about the same in appearance.
The treatment is conservative and expectant with immobilization.
Results in such cases are uniformly good.
