Ha, Kim, Hong, Sim, and Kim: Comparison of Operative Management in Distal Radius Fractures Using 3.5 mm Versus 2.4 mm Volar Locking Compression Plates

Abstract

Purpose

To evaluate clinical and radiological results using 3.5 mm & 2.4 mm volar locking compression plate (LCP) in distal radius fractures.

Materials and Methods

This study reviewed the results of 115 cases of distal radius fractures treated with 3.5 mm volar LCP (73 cases) & 2.4 mm volar LCP (42 cases) from September 2003 to June 2009. The radiographic results were evaluated by radiographic assessment, and the clinical results were evaluated by Knirk and Jupiter's criteria, Modified Mayo wrist scoring system and DASH score.

Results

Radiological evaluation of the radial length, radial inclination, volar tilt and intraarticular step off were improved both 3.5 mm volar LCP and 2.4 mm volar LCP. Nine cases of arthritis occured in 3.5 mm volar LCP and 7 cases in 2.4 mm volar by using the Knirk and Jupiter's criteria. The mean score evaluated by Modified Mayo was 86.7 in 3.5 mm volar LCP and 84.8 in 2.4 mm volar LCP. DASH score was 11.2 point in 3.5 mm volar LCP, 10.9 point in 2.4 mm volar LCP. All cases showed bone union showing no evidence of malunion, nounion, nor metal failure.

Conclusion

Distal radius fractures treated with 3.5 mm volar LCP and 2.4 mm volar LCP show satisfying radiological and clinical outcome.
