We hypothesized that volar locking pate fixation using a minimum number of screws-four in the distal row and two in the shaft of the plate-will provide sufficient stability for unstable extra-articular fractures of the distal radius. We aimed to compare the biomechanical properties of different numbers and locations of screws in volar locking plate fixation and describe the clinical and radiological outcome of plate fixation using a minimum number of screws for distal radius fractures. ⋯ In the dorsally comminuted, extra-articular, nonosteoporotic distal radius fractures, the minimum number of screws-four in the distal row and two in the shaft-in volar locking plate fixation can provide sufficient stability. Further biomechanical studies involving osteoporotic bone will be necessary to confirm the results because volar plate fixation is most commonly used in patients with osteoporosis.
