The plate was developed with theformula given in Chapter XIII. The time was about right for thehand, but slightly too short for the wrist and larger bones; anothersecond would have been better, but would have overexposed thehand. Fractures and displacements in the carpal bones are generallyaccompanied by fractures in either the end of the radius or ulna,and often in both. Fig. 138 shows a skiagraph of an ugly and very

Injuries ofthis kind should always be skiagraphed before reduction is at-tempted. No physician who cares anything for his reputation canafford to treat a case of this kind blindly, as the results will be badenough after the very best treatment in the hands of an expert inthe handling of bone injuries. Fig. 139 shows a dislocation at the wrist and a fracture of theradius, with the fragment on the dorsal surface. This was a neg-lected injury, and was seen several weeks after the accident. Itwill be noticed that this is a very difficult fracture to reduce becausethe fragment from the radius is displaced to its upper surface and 310 PRACTICAL ELECTRO-THERAPEUTICS AND X-RAY THERAPY the end of the radius is left in the shape of a wedge.
