RESUMO
INTRODUCTION: Isolated acute distal radioulnar joint (DRUJ) dislocation is a rare injury that should be early recognized and treated promptly to avoid the limitation and disability associated with delayed diagnosis and management. CASE PRESENTATION: We present a patient with a traumatic dorsal isolated DRUJ dislocation who was successfully treated with a closed reduction and k-wire pinning along with cast immobilization. DISCUSSION: Previous reports of distal radioulnar joint dislocation have described the mechanics of this injury as well as a guidance to diagnosis and treatment. Closed reduction, stabilization of wrist joint, and early mobilization of elbow joint can help in preserving the joint function and a faster recovery. CONCLUSION: Closed reduction under general anesthesia, DRUJ stabilization by k-wire pinning, and above elbow casting can be successful in most cases. We recommend an early transition to below elbow cast to encourage early elbow range of motion and prevent joint stiffness.
