Fracture of the distal radius. A prospective comparison between trans-styloid and Kapandji fixations.
We performed a prospective study on 96 patients with extra-articular or intra-articular fractures of the distal radius with a dorsally displaced posteromedial fragment. After closed reduction, we compared trans-styloid fixation and immobilisation with Kapandji fixation and early mobilisation. Forty-two patients of mean age 57.1 years +/- 18.1 (SD) were treated by trans-styloid K-wire fixation and 45 days of short-arm cast immobilisation. Fifty-four patients of mean age 57.7 years +/- 18.7 (SD) had Kapandji fixation and immediate mobilisation according to the originator. All the patients had clinical and radiological review at about six weeks and at 3, 6, 12 and 24 months after the operation. Pain, range of movement and grip strength were tested clinically, and changes in dorsal tilt, radial tilt, ulnar variance, and radial shortening were assessed radiologically. Statistical analysis was applied to comparisons with the normal opposite wrist. Pain and reflex sympathetic dystrophy were more frequent after Kapandji fixation and early mobilisation, but the range of motion was better although this became statistically insignificant after six weeks. The radiological reduction was better soon after Kapandji fixation, but there was some loss of reduction and increased radial shortening during the first three postoperative months. The clinical result at two years was similar in both groups.
