UPPER EXTREMITY.
Gunshot Fracture of the Right Humerus, with Lodgment of the Missile.
Wound of entrance, antero-external aspect of upper third of arm.
Wound of exit, none.
The missile, deformed by ricochet, struck the bone with greatly reduced velocity and without sufficient energy to perforate the bone by which it was deflected slightly from its course and lodged in the arm.
This is something of the same effect that might have been caused by a shrapnel ball, under the same ballistic conditions with a normal shrapnel velocity giving about the same penetrating force.
The wound, without infection, is in the first week or two of repair, before any callus has formed.
Treatment is expectant.
