The case is similar in course and results to that shown in the preceding [plate 90].

Shrapnel—Plate 92.

UPPER EXTREMITY.
Gunshot Fracture of the Right Humerus,
with Lodgment of the Missile.

The missiles, shrapnel balls deformed by ricochet, were multiple, with a course from without inward and diagonally downward. The streaks of metal particles along the seat of fracture indicates the path of a shrapnel ball or fragment from the point of impact to the lower fragment of the fracture, where several deformed shrapnel fragments are lodged. Multiple wounds by shrapnel are common.

The wounds of entrance were small. There was no wound of exit. The wound was not infected. This is another evidence that does not defend the inference that ricocheted missiles are prone to introduce elements of infection into a wound.

The plaster dressing does not seem to meet the indications for support of the fracture.

The treatment is conservative in such cases.
