The conditions were much the same as those shown in plates 28 and 29, except that the striking energy of the projectile was somewhat greater with the velocity of mid range.
The treatment, without infection, is that of a simple fracture.
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.
The course of the bullet was in an anteroposterior direction at a high velocity of short range, which, imparting its energy to the fragments, drove some of them through the tissues as “secondary missiles” and caused a laceration of the wound to exist.
The longitudinal fragmentation and splitting indicates a considerable energy of the projectile, which may have been deflected, as its long axis was turned somewhat from the trajectory at the time of impact.
The emergency treatment is antiseptic dressing and splint immobilization.
The subsequent treatment is conservative with the removal of detached fragments and with control of infection as the course indicates.
The course of the bullet was transverse through the middle of the forearm, striking the posterior border of the ulna.
Small fragments were broken from the posterior wall of the medullary canal, without destroying the longitudinal continuity of the anterior wall.
The velocity of the bullet was probably that of mid-range, as the striking energy of the impact was fairly great.
The posterior surface of the forearm lay next to the plate.
The emergency treatment is antiseptic dressing and splint immobilization.
The subsequent treatment is that of a simple fracture, as infection is not usual.
