[Using the DRP 2.4 device for volar plating of distal radius for dorsally displaced wrist fractures. Report of 22 cases].

OBJECTIVE: Our first experience of palmar plating for dorsally displaced distal radius fracture with locking compression plate showed good results. But ancillary tools was ineffective, so we report our early experience with the DRP 2,4 device.

METHODS: Between January and October 2004, 22 patients (16 women, 6 men), mean age 56,8 years (age range: 24-77 years), underwent internal reduction and fixation using DRP 2.4 by Henry's approach. By AO classification there was 10 A3 and 12 C1 or C2 fracture. On pre operative X Ray, radial inclination was 13.9 degrees , and dorsal tilt was 27 degrees .

RESULTS: Seventeen patients were reviewed with mean follow-up of 11 months (5 to 17). On postoperative X Ray, radial inclination was 22,7 degrees and palmar tilt was 2,1 degrees. At 6 month radiological findings found no loss of postoperative reduction. According to SOFCOT's criteria's, we noticed 9 anatomical results and 8 moderate malunion. Clinical results (Green and O'Brien) showed 6 excellent, 7 good, 4 fair and no poor results. Mean DASH score was 13.5. Strength recovery was 82% of opposite side. Complications concerning 6 patients with, 4 reflex sympathetic dystrophy, and 2 screwdriver breakage during insertion.

DISCUSSION: Volar plating with DRP 2.4 is an effective technique, but obtain anatomical reduction remind challenging for the surgeon.

CONCLUSION: DRP 2.4 volar plating is an effective treatment for dorsally displaced fracture. Controlled study with orthopaedic reduction and K Wire fixation are need for determining the place of each treatment.
