Rifle—Plate 39.
UPPER EXTREMITY.
Gunshot Fracture of the Left Ulna.
The course of the bullet, with the velocity of long range, was anteroposterior through the lower third of the forearm, striking the outer side of the bone. The initial velocity of the projectile was much reduced, as is shown by the tendency to puncture the bone without much fragmentation.
There was no displacement of fragments as a direct result of the impact, although muscular contraction has caused some slight subsequent overriding.
The wounds of entrance and exit were about the same, if not quite similar in appearance.
The emergency treatment is the conventional antiseptic dressing with splint immobilization.
The subsequent treatment is usually that of a simple fracture, as infection in such cases is rare.
