The proximal radioulnar joint in consideration of the distal radioulnar joint

Abstract

The movement of the forearm follows acomplex interplay of three main components: the proximal and distal radioulnar joint and the interosseous membrane. Injuries to one or even all components have ahuge impact on the integrity of this system. The Essex-Lopresti lesion presented ahigh challenge in clinical diagnostics as well as therapy. Reconstructions of the length and stability are essential for asatisfactory postoperative outcome. If areconstruction of the radial head by osteosynthesis is not possible, aradial head prosthesis should be implanted in the case of longitudinal instability - avoiding overlapping and/or oversizing. The reconstruction of the interosseous membrane should be considered, as well as the assessment of the distal radioulnar joint and/or the triangular fibrocartilage complex. Various reconstruction options are available in this regard.
