Rifle—Plate 32.
UPPER EXTREMITY.
Gunshot Fracture of the Ulna.
The course of the bullet was transverse through the arm at the junction of the middle and upper thirds from behind the radial border externally to the ulnar border internally, striking the wall of the medullary canal with a punching effect that partly split off short longitudinal fragments and caused transverse and longitudinal cracks, without separation or displacement of fragments.
The same ballistic conditions applied to cancellous tissue at the end of the bone would probably have bored through it without fracture.
This effect is generally seen in wounds of small-caliber bullets traveling at reduced velocity of long range.
The treatment is that of a simple fracture.
Results, in such cases without infection, could not be bad.
