Minimally invasive stabilization of an isolated dorsal distal radioulnar joint dislocation using a suture button suspension system

Abstract

Isolated dislocation of distal radioulnar joint (DRUJ) is rare. The first choice of treatment is closed reduction and casting. If it is unsuccessful, operative intervention is the next step. In this report, we present a patient suffering from an unstable DRUJ dorsal dislocation after attempting closed reduction under general anesthesia. The instability was confirmed clinically and radiologically. The surgical treatment included a minimally invasive stabilization technique in which a suture button suspension system was applied to the extra-articular part of a DRUJ. At a 6-month follow-up, a pain-free full range of motion of forearm and stable DRUJ were achieved. Level of evidence: 4.
