Both Bone Forearm Fracture with Complex DRUJ Dislocation: What Are the Odds?

Abstract

Background Distal radioulnar joint (DRUJ) dislocation can occur as an isolated injury or in association with fracture radius (Galeazzi fracture-dislocation), Essex–Lopresti lesion or, rarely, with fracture of both radius and ulna (termed “Galeazzi type fracture”). DRUJ dislocations can be simple or complex. While simple DRUJ dislocation can be reduced by closed methods once the associated fractures are fixed anatomically, complex dislocation does not reduce by closed means. A complex DRUJ dislocation occurring in a both bone forearm fracture is an extremely unusual pattern of injury.

Case Description We describe the clinical presentation, intraop findings, management, and follow-up of two such cases of both bone forearm fracture with complex DRUJ dislocation. In both the cases, the ulnar head was found to be buttonholed through extensor retinaculum between the extensor tendons. Open reduction had to be done via dorsal approach. Timely intervention allowed good results in both the patients.

Literature Review Several authors have reported simple DRUJ dislocations in both bone forearm fractures; however, we could come across only three cases of complex DRUJ dislocation in a both bone forearm fracture. A summary of various series and reports on these injuries is presented.

Case Relevance Through this case report, we want to highlight this unusual association and emphasize on sequence of fixation, so that this perilous injury pattern is not missed, and favorable outcomes could be obtained through appropriate and timely intervention.
