. A practical treatise on fractures and dislocations. URES. of the surgical neck (as I have here defined the latter) is arbitrarilydrawn and I doubt, for the reasons given, if it can often be recognizedclinically.

Independent mo-bihty of only the upper part of the tuberosity would at least show thatthe fracture was high. Two specimens described and pictured by R. W. Smith (Figs. 109and 110) show healing with marked impaction in one case and withcomplete reversal of the head in the other. In the one shown in , examined five years after the accident, the head of the humeruswas found to have been drawn into the cancellated tissue of the shaftbetween the tuberosities so deeply as to be below the summit of the Fig. 109.
