CLINICAL RELEVANCE: At the level of the proximal border of the distal radioulnar joint, isolated distal radius translation does not significantly affect forearm rotation.Copyright © 2014 American Society for Surgery of the Hand. Published by Elsevier Inc. All rights reserved.

CONCLUSIONS: In this cadaveric model, translation of the distal radius fragment in the lateral direction had no effect on forearm rotation.

METHODS: Ten fresh cadaveric limbs underwent distal radius osteotomy just proximal to the distal radial-ulnar joint to simulate an extra-articular distal radius fracture. We used an Agee Wrist Jack external fixator to create increasing magnitudes of distal fragment lateral translation in 2-mm increments. Forearm rotation was measured using a 3-dimensional camera at each magnitude of lateral translation.

PURPOSE: To determine the effect of lateral translation of the distal radius in the coronal plane on forearm rotation after distal radius fracture.

RESULTS: Total forearm rotation for the intact specimen and 2, 4, 6, and 8 mm (maximal) radial translations was 186degree +/- 53degree, 188degree +/- 54degree, 189degree +/- 55degree, 190degree +/- 57degree, and 193degree +/- 59degree, respectively. There was no significant difference for any magnitude of radial translation. The average maximal radial translation possible before radioulnar abutment was 8 +/- 0.5 mm.
