Use of the Extensor Carpi Ulnaris Half-Slip for Treating Chronic Neglected Volar Dislocation of the Distal Radioulnar Joint.

Volar dislocation of the distal radioulnar joint (DRUJ) is a rare injury. Furthermore, few reports exist regarding DRUJ dislocation with simultaneous elbow dislocation. Elbow dislocation is easily diagnosed and reduced, whereas a DRUJ dislocation is easily missed because of an inaccurate or missed examination of the wrist, which results in a chronic condition. We experienced a case of simultaneous elbow and volar DRUJ dislocation; the latter was found 2 months postinjury. To treat chronic volar dislocation of the DRUJ, surgical methods should include reconstruction of the triangle fibrocartilage complex because of scar tissue and severe instability. In this paper, we describe triangle fibrocartilage complex reconstruction by using the extensor carpi ulnaris half-slip. It is the first report of applying this technique for chronic volar DRUJ dislocation. This technique has a role in creating strong stabilization of the DRUJ and can be an effective treatment option.
