The treatment of distal radius articular fractures of C1-C2 type with DVR plate: analysis of 40 cases

The aim of this investigation was to evaluate the efficiency of fixed angle plates DVR in the treatment of C1 and C2 type articular wrist fractures according to the AO classification. From July 2005 to March 2009, 40 wrist fractures were treated: 18 were of C1 type while 22 of C2 type according to AO classification. The age of patients varied from 25 to 79 years old. The average length of follow-up was 17 months (range, 4–37 months). The average articular motility was flexion 59.4° and extension 62.7°. Final radiographic parameters were of 18.7° of average ulnar inclination, 10.3° of average dorsal inclination, and 1.45 mm of negative ulnar variance. All patients were reassessed according to Mayo Modified Wrist Score getting a very good/good result in 82% of cases and a medium/poor one in 18%. The DASH score pulled off 46.3 points in the first group, 5.1 in the second group, and 6 in the third one. The statistical analysis based on Student’s t test showed how C1 and C2 classification did not influence the results using the same treatment. DVR plate showed a very good reliability and a sufficient stability with both C1 and C2 fractures.
