I have myself seen one such case,1 but Iregret to say that my examination of the condition of the arm was not such asto enable me to give a very satisfactory account of the cause and symptoms of the accident. Referring, however, to theFig. 144. experiments upon the cadaver detailed in the succeeding pages, it will be seen thatI have been able to produce this fractureby forced palmar flexion of the Fracture of the Styloid ProcessesAccompanying Colless Fracture.—Ibelieve I have seen two examples of a Fracture ot radius and displacement „ . l,. , ., forward. (R. W. Smith.) fracture commencing on the radial side of the bone and terminating in thejoint, the separated fragment including considerably more than the styloidprocess; but neither of these cases has been verified by an autopsy. Nelaton observes that all the varieties of this fracture which he has seen areoften accompanied with fracture of the styloid apophysis of the ulna, and witha tearing of the triangular ligament. Cameron, also, thinks it more common inconnection with a Colless fracture than has generally been supposed; and, inconfirmation of this opinion, reports five cases which he has himself Dislocation of the Lower End of the Ulna in Connection with CollessFracture.—Dr. Moore, of Rochester, N. Y., has demonstrated, by exami-nations upon the cadav
