Notwithstanding, therefore, the opinions of Dupiiytren, Diday, &e., &c., we think that, as a general rule, in the case of Colics' fracture the prognosis is favourable. It may be otherwise, if the styloid process of the radius be elevated much above its natural level, if the hand has quitted, par- tially, the lower end of the ulna, so as to be carried "par un inouvetncnt de totalite " outwards, and if the case has not been early recognised. Anatomical characters nfthe Fracture. — On dissection, it will be found that the hard swelling which occupies the back part of the hand and wrist, is caused by the displacement backwards of the lower fragment of the radius, and the carpus carried with it in this direction. As a consequence of the altered direction of the radius, we find that the aspect of the carpal articular surface of this bone is altered, and instead of being directed, as it normally is *, downwards and somewhat forwards, it is now directed downwards and backwards ( fig. 933.) ; the carpus and metacarpus retaining Fig. their connexion with the broken radius must always thus follow this bone in its derange- ments, and cause the characteristic dorsal convexity above alluded to. The change of direction of the articular surface of the radius is well shown by measuring the length of the broken radius in these cases, both on the palmar and dorsal aspect of this bone longi- tudinally, when it will be found that in Colics' fracture, the posterior measurement is several lines less than the anterior, which is exactly the reverse of what this measurement normally should be.
