The treatment is conservative with free incision and drainage in the management of infection. [Illustration: Plate 44.] RIFLE--PLATE 44. UPPER EXTREMITY. Gunshot Fracture of the Third Phalanx. The course of the bullet was anteroposterior through the base of the proximal phalanx of the middle finger, with a velocity of long range. It practically punctured the bones and split off a few fragments without displacement. The wound of entrance would be much the same as the wound of exit, with the latter, but a little larger. Treatment is conservative. [Illustration: Plate 45.] RIFLE--PLATE 45. CHEST. Penetrating Gunshot Wound of the Chest, with Lodgment of the Projectile Near Posterior Chest Wall. Point of entrance, pectoral border and fourth rib. Point of exit, none. The distinct shadow of the angle of the ribs shows that the posterior chest wall was next to the photographic plate, and that the larger and less distinct outline of the anterior portions of the upper ribs was farther from the plate. The nearly normal size of the shadow of the projectile shows it to be much nearer the posterior than the anterior chest wall. The blurred outline shows it to have moved with respiration. Such conditions locate its position within the thoracic cavity. The emergency treatment is antiseptic dressing and rest. The subsequent treatment depends upon pleural involvement or the extremely rare infection of the lung. These cases are nearly all aseptic, and if the great vessels and nerves of the chest escape injury results are generally favorable. [Illustration: Plate 46.] RIFLE--PLATE 46. PELVIS. Gunshot Wound of the Pelvis, with Lodgment of the Missile in the Abdomen. The course of the bullet was from behind forward, striking the crest of the ilium, on which it was deflected, and spattering off some lead fragments. The slight penetration indicates a velocity of extremely long range and a striking energy lessened by ricochet. The irregular outline of the shadow of the projectile shows its deformity, and the blurred outline indicates intra-abdominal movement with respiration. While the missile, as revealed by its shadow, is not a shrapnel ball, the distribution of lead particles is more suggestive of a shrapnel than of a rifle projectile, and the ballistic conditions are more characteristic of the former than of the latter. There was no abdominal reaction; the invasion of the abdomen was revealed by the radiograph. The treatment in such cases is noninterference unless subsequent developments furnish definite indications. [Illustration: Plate 47.] RIFLE--PLATE 47. LOWER EXTREMITY. Gunshot Wound of the Gluteal Region, with Lodgment of the Bullet Near the Ischium. Wound of entrance, over gluteal prominence on a transverse line through the great trochanter. Wound of exit, none.
