The bones of the forearm or the hand can be as readily skiagraphed through a voluminous surgical dressing or through the ordinary clothing, as when the parts are entirely divested of any covering. Even bed-ridden patients can be skiagraphed through the bed-clothes, and, therefore, without danger from exposure.
When any time has elapsed after the accident, the great swelling which often quickly follows such injuries still further obscures the diagnosis by manipulation. The X rays, however, are oblivious, or nearly so, of all swelling, and the bones can be skiagraphed in the thinner parts of the body at present, say up to the elbow and the ankle, with very great accuracy.
So, too, in an equal number of cases, bullets and shot have been located, even after a prior fruitless search, and have been successfully extracted. It will be noticed that their denser shadow is seen even through the bones of the hand themselves, for the hand was skiagraphed palm downward. Professor von Bergmann of Berlin has uttered, however, a timely warning upon this very point.
In the dead body, arteries filled with substances opaque to the X rays, such as plaster of Paris or cinnabar mixtures, have already been skiagraphed successfully. It is not at all improbable that calcified arteries in the living subject may be equally well shown. So, too, when we are able to skiagraph through thick tissues, we may be able to show such deposits in the internal organs of the body.
Sydney Rowland skiagraphed the hand, and showed that there was only a bridge of bone uniting the last two joints of the finger. An anaesthetic was administered, and with very little force the bridge of bone was snapped, the finger saved, and the normal use of the hand restored. Deformities of bone can be admirably shown.
