Malgaignedescribes a case in which the fragment apparently had not reunitedwith the shaft, and yet the patient could use the limb actively, andeven handle a sword or a foil. On examination it was found, how-ever, that the vigor and strength of the arm depended largely upon itsposition, being greatest when the hand was supinated and the armdependent, and disappearing almost entirely when the arm was raisedabove the horizontal line. Failure of union, as in the case just mentioned, is not very uncom-mon ; the upper fragment may remain freely movable, or it may to the humerus. In a case of the latter condition which came FRACTURES OF THE BONES OF THE FOREARM. 291 under my observation thirty-five years after the accident (Fig. 185)the forearm could be completely flexed and could be extended to 135degrees, the force of extension being ve
