A prospective randomized comparison of variable-angle and fixed-angle volar locking plating for intra-articular distal radius fractures

The Journal of Hand Surgery May 09, 2021

Nishiwaki M, Terasaka Y, Kiyota Y, et al. - This study sought to correlate clinical and radiographic outcomes of using a variable-angle volar locking plate (VAVLP) with those of using a fixed-angle volar locking plate (FAVLP) for treating unstable intra-articular fractures of the distal radius. Researchers randomized a total of 120 individuals with unstable intra-articular fractures of the distal radius to open reduction and internal fixation with a VAVLP (n = 60) or a FAVLP (n = 60). They used posteroanterior and lateral radiographs to assess standard radiographic parameters before surgery, in the immediate postoperative period, and at 1 year. Using computed tomography, plate prominence and articular congruity were evaluated at 6 months. The findings revealed that individuals with intra-articular distal radius fractures can expect good functional and radiographic outcomes with VAVLP or FAVLP fixation. The outcomes demonstrate that VAVLP may be more prone to technical errors, leading to complications, whereas the FAVLP is more likely to need supplementary fixation.
