As the impact was direct, the energy producing such effect was that of low velocity.
The great radiographic penetration shown in this plate gives the shadows of the ball great distinctness and definite outline, especially in the line of fracture, although its opposite border is not in such sharp contrast. This appearance, together with the very slight enlargement, leads to the suspicion that the ball lies posteriorly, but a larger metal fragment, below the ball, is less clear and suggests a position anterior to the bone. With the posterior surface of the arm next to the plate and with but little difference in the distance from the plate to either the anterior or posterior surface of the bone, it is not easy to determine the location of the ball in the anteroposterior direction, but it would seem to be on the anterior surface of the bone.
The wound is not infected. The treatment is conservative and results favorable.
The subsequent course would probably indicate the removal of a foreign body from a site so near the joint.
