Rifle—Plate 40.

UPPER EXTREMITY.
Gunshot Fracture of the Ulna.

The course of the bullet was obliquely anteroposterior through the lower third of the forearm, striking the radial edge of the bone with a velocity of long range.

The wounds shown in plates [35] and [39] represent conditions similar to those causing this wound, except that the ranges were progressively greater.

In this case the projectile exhibited a punching effect at the point of impact, and although the lines of force are shown in characteristically divergent fissures, the energy imparted to the fragments—less than in the preceding cases—has not been sufficient to separate or to displace the fragments.

The emergency and subsequent treatment is conventionally conservative, as in the preceding cases.
