Comparative study between fixed-angle and polyaxial screws in distal radius fixation with two volar locking plates.

Introduction: When treating a distal radius fracture with a volar locking plate (VLP), numerous plate-screw designs are available. To date, there is not a screw fastening system with a clear superiority among the others.

Hypotesis: Fixed-angle screws are superior to polyaxial screws in distal radius VLP fixation with respect to screw protrusion and reduction preservation.
