Roentgenologic alternatives in the diagnosis of diseases of the urinary tract.

The extent to which active movements are practised by the patient while the splint is still on, varies with different temperaments. Some cases require more encouragement than others. If after the removal of the splint there is still some limitation of movement at the metacarpo-phalangeal joints, the application of heat, preferably in the form of paraffin baths, followed by active movements, is found to be the most effective way of restoring mobility. The position of fixation. Most cases can be treated with the hand in line with the forearm, as described above. In some cases, however, it is found that, although the reduction is easily performed, the deformity easily recurs. The correct position can in all cases be maintained if the wrist is flexed and is maintained flexed. This position is not adopted as a routine because the fingers cannot be so fully used and because it results in a delay in the return of movement in the wrist yet it must of necessity be sometimes adopted. No hard and fast rules can be laid down as to when to use the flexed position, but with experience it is possible to judge at the time of reduction whether the deformity is likely to recur, or whether the corrected position can be maintained by a plaster with the hand straight.
