Optimal positioning of the DVR plate in distal radius fractures: a cadaveric examination of a referencing technique.

Abstract

Volar locking plates have revolutionised the treatment of distal radius fractures but complications are not uncommon. We present a cadaveric study and a technical tip to assist in the accurate and reproducible placement of one such plate. We placed 25-g needles in the distal radioulnar joint and radiocarpal joint and measured the distance from these needles to a DVR plate in its optimal position. This distance measured 5mm, corresponding to the width of the depth gauge handle. Placing this next to needles in these joints can help pre-plan the most distal and ulnar extent of the plate allowing for reproducible optimal positioning of the DVR plate. The technique developed uses the existing kit and is simple and easy to build into one's existing fixation technique.
