Foreign bodies in the hand are easily shown. Especiallyneedles in the palm often come under the observation of the prac-titioner. CHAPTER XII HAL FORM A TIONS As previously mentioned, the great scientific and practicalvalue of the Rontgen rays is also evident in the study of congenitalmalformations. Skiagraphy of the extremities especially has givenmore valuable information than dissection. The exact anatomicaldiagnosis that it enables us to make informs us whether surgicalinterference in a case of malformation is possible, and if so, out-lines clearly our modus operandi beforehand. The ingenious oper-ations of Bardenheuer (division of the ulna for carpal implanta-tion) and of von Eiselsberg (transplantation of the toe),
