 The DVR® volar locking plate system can provide rigid stabilization for a distal radius fracture by taking full advantage of the principle of subchondral support and buttress fixation. Although the clinical results have for the most part been promising, we have sometimes encountered cases of secondary loss of reduction, especially when the fracture has considerable dorsal comminution and a fracture void, and we recently began using a subchondral bone tamp (SBT) technique to maintain anatomical reduction in such cases. The SBT technique is similar to the techniques used to for manage depressed intra-articular fractures. Access to the subchondral bone is gained through the fracture site or a cortical window in the metaphyseal bone. A tamp or elevator is then inserted and used to produce a compact subchondral zone with local cancellous bone, which is effective as a subchondral support system. The purpose of this article is to describe our SBT technique and its efficacy as a means of treating distal radius fractures with a massive fracture void.
