The dissection re- vealed a simple and transverse fracture of the carpal extremity of the radius, with a dis- placement backwards of the lower fragment, as with ordinary cases of fracture of the radius in the immediate vicinity of the wrist- joint, a species of injury, which in this city is known by the name of" Colics' ; It would also appear to Malgaigne, Bouchet, and Voillemier, that this fracture may be the result of a sudden and violent flexion of the hand without the patient having had any fall. This fact was first established by Bouchet, who, in endeavouring to produce dislocation of the wrist on the dead body, only caused in his experiments fractures of the inferior ex- tremity of the radius ; sometimes with other disorders, and more particularly with a simul- taneous fracture of the styloid process of the ulna. Symptoms. — If Colles' fracture of the radius be produced by a fall, the patient will, sometimes, be able to say that at the moment of the accident he felt a sensation of some- thing having given way near to the wrist-joint. The inferior extremity of the forearm ami the hand swell ; the finger^ are semi-Hexed, and the patient experiences the greatest diffi- culty in performing the ordinary movements of the hand, or forearm. He usually pre- sents himself to us with the hand of the injured forearm resting on its ulnar margin, and supported by the other hand, and in a middle state between pronation and supina- tion. The posterior surface of the forearm usually represents a considerable deformity; for a depression is seen to exist about one inch above the line of the wrist-joint, whilst a con- siderable swelling occupies the wrist itself and metacarpus ; indeed, the carpus and base of the metacarpus, appear to be thrown back- wards so much, as at first view to exc
