The position of the hall is indicated by the outline and depth of shadow of the normal size of a shrapnel ball. The ball must therefore be very near the plate and behind the head of the humerus.
There is no injury to the bone. The slight deformity of the ball was caused by ricochet before it caused the wound, as no particles of lead are seen on the bone to account for the impact of the missile.

Shrapnel—Plate 86.
UPPER EXTREMITY.
Gunshot Fracture of the Clavicle.
The ball ranged from before backward and upward, comminuting the outer half of the clavicle.
The fragments have been removed. The particles of metal which mark the path of the ball lie in front of the acromion process of the scapula, because lack of density and indistinct outline of the shadows show them to be farther from the photographic plate than the spine of the scapula which rested on the plate, escaping the imminent danger of wounding the subclavian vessels.
