[ A comparison of 2 methods of plastic cast fixation in treatment of loco classico radius fracture . A prospective , randomized study ] . The purpose of this study was to compare the functional and radiological result of two different positions of the wrist in a plaster cast following Colles ' fracture . For this prospective study , each of 50 patients with type A 2.2 , A 3.3 , C 1.2 or C 2.2 ( AO classification ) fractures of the radius was randomly assigned to one of two groups . Both groups were treated in the same way as far as anaesthesia and reduction were concerned . The only difference in treatment lay in the position of fixation in plaster . In group 1 the wrist was immobilized in neutral flexion-extension . In group 2 the wrist was dorsiflexed 20 degrees , while the carpus was pushed in a volar direction by an impression in the plaster cast . At review 2-7 years after the accidents , the two groups were compared with reference to symptoms , range of motion at the wrist , power of first closure and radiographic appearance . In group 1 there were 5 patients with significant disability , compared with only 1 in group 2 . A significant difference was found in the range of movement between the two groups for flexion and ulnar abduction ( p < 0.01 ) . The loss of power of first clenching ( difference between injured and healthy hand ) was 6.2 mmHg for group 1 and 3.8 mmHg for group 2 ( not significant ) . The radiographic examination showed significant differences both in sagittal inclination ( p < 0.001 ) and in radial shortening ( p < 0.05 ) . ( ABSTRACT TRUNCATED AT 250 WORDS )
