Proceedings of Meeting of the Association of Military Surgeons of the United States. . the Lower Extremity of the Radius. 535 firm thumb pressure upon the back of the lower fragment willpush it forward into place. If the hand is then brought intopalmar flexion the fracture surfaces fall together, and the normalcontour of the bone is restored, the carpo-nlnar ligament is re-laxed and the ulna assumes or may be pressed up into proper po-sition in relation to the radius. Should the first effort to secureperfect reduction be unsatisfactory imits results, renewed and morethorough attempts should be made, until it is evident that the bestpossible position of the fragments has been secured. Ordinarily there is but little tendency to renewed displace-ment after reposition, provided the part is protected from furtherdirect force. Any pressure on the anterior surface of the wristwill bear upon the projecting anterior lip of the lower fragment,and may crowd that fragment back to the plane of the shaft of thebone. Anteroposterior pressure also tends to crowd the soft tis- 3pl i nt.

The first indications areto give the injured part support and protection, and bv immobi-lization and equable compression to limit effusion and promote re-pair. With the subsidence of the primary wound reaction, espe-cial precautions to maintain the mobility of the wrist and fingerjoints are indicated. In very many cases the application of a Manuel roller bandageand the support of a sling will be all the apparatus required. Asmall compress, about one-quarter inch in thickness should befirst adjusted upon the front of the forearm, its lower edge beingpermitted to come down nearly but not quite to the level of theanterior lip.
