Radiographic alignment of unstable distal radius fractures fixed with 1 or 2 rows of screws in volar locking plates


Neuhaus, Valentin; Badri, Omar; Ferree, Steven; Bot, Arjan G J; Ring, David C; Mudgal, Chaitanya S (2013). Radiographic alignment of unstable distal radius fractures fixed with 1 or 2 rows of screws in volar locking plates. Journal of Hand Surgery, 38(2):297-301.

Abstract

PURPOSE: We tested the null hypothesis that there is no difference in the change in volar tilt of the articular surface of the distal radius on lateral radiographs obtained before suture removal and 3 months or more after surgical fracture fixation when 1 or 2 rows of screws are used in the distal part of a volar locked plate. METHODS: We retrospectively identified 364 consecutive patients with a distal radius fracture treated by 2 surgeons with open reduction and volar locked plate fixation between 2007 and 2011 at our institution. A manually case-matched design with one-to-one matching of 2 different strategies for screws in the distal part of the plate (1 row versus 2 rows) on the basis of sex, AO type, presence of dorsal comminution, ulna fracture, mechanism of injury, and age (± 8 y) resulted in a group of 34 pairs, 68 total fractures. Radiographic alignment was measured before suture removal and 3 months or more after surgery. RESULTS: The change in volar tilt of the articular surface was -1.2° in the 1-row group and -0.9° in the 2-row group, which was not significantly different. The secondary displacement of radial inclination and ulnar variance were likewise small and not statistically significant. CONCLUSIONS: We found no advantage of 2 rows of distal screws over a single row of screws with respect to maintenance of achieved restoration of volar angulation after volar locked plate fixation of AO type A and C fractures of the distal radius. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic III.
