A practical treatise on fractures and dislocations. 308 FRACTURES. by the history and the effect upon the soft parts of the direct violencewhich has caused the fracture, the doubt can be removed by noting thatpain at that point is aroused by the effort actively to extend the elbowagainst opposition. If the radius remains entire and is not dislo-cated at either end, there can be no shortening of the limb, no over-riding of the fragments, and displacement, if present, must be recogrnized by following the outline of the bone w^ith the finger. Crepitusand abnormal mobility may be obtained by grasping the limb aboveand below the fracture and making pressure alternately upon the frag-ments with the fingers, or by seizing the fragments between the thumband fingers and moving them forward and backward upon each important and not infrequent complication is dislocation of thehead of the radius forward; it should always be suspected when thereis marked displacement of the fragments of the ulna or unusual swell-ing at the elbow. Fig. Fracture of ulna, with dislocation of head of radius -forward. The prognosis is good as regards repair and preservation of function. Reduction. Reduction can be made only by appropriate pressure uponthe displaced fragments, traction being practically without value. Thedisplacement which it is most important to overcome is the lateral onetoward the radius, and that should be met in the same way as afterfracture of both bones, that is, by pressing the thumb and fingers inbetween the bones. As the radius acts as a splint to prevent overriding of the fragmentsthe surgeon^s chief care is to secure immobility and prevent lateral orangular displacement. - This can be done by the anterior and posteriorsplints used in fracture of both bones, or by a rectangular splint fast-ened against the inner side of the arm and semi-pronated forearm, orby a moulded plaster splint. In some cases it may be necessary to FRACTURES OF THE BONES OF THE FOREAR
