          Abstract

          Introduction:

          Isolated dislocation of the distal radioulnar joint (DRUJ) is a rare phenomenon. Approximately 50% of isolated DRUJ dislocations are undiagnosed or diagnosed late with significant functional consequences. This clinical injury is rarely described in the literature and management is not well established. We reported a case of volar DRUJ dislocation early diagnosed.

          Case Report:

          A 36-year-old man was diagnosed with an isolated volar dislocation of the DRUJ. The clinical examination, X-rays, and computed tomography scan allowed an early diagnosis. A reduction by external maneuvers was performed and the patient was immobilized in an above elbow plaster cast for 6 weeks. Magnetic resonance imaging did not reveal any capsuloligamentous lesions requiring surgery. Evolution was favorable.

          Conclusion:

          Isolated volar dislocation of the DRUJ is an uncommon injury which can be easily missed. Missed or late diagnosis may lead to significant morbidity. Early diagnosis and treatment of such injuries usually results in excellent functional recovery.

          Minimally invasive anesthesia in wide awake hand surgery.

          Tumescent minimally invasive local anesthesia is eliminating the need for sedation and proximal nerve blocks as well as all of their risks, costs, and inconveniences. It has facilitated advances in procedures such as hand fracture reduction, tendon repair, and tendon transfer by allowing the surgeon to see cooperative patient active movement during the surgery. It has improved the patient experience for simple hand operations such as carpal tunnel release.

            Locked volar distal radioulnar joint dislocation

            Highlights • Volar dislocation of the distal radioulnar joint is a rare injury and can be easily missed. • The stability of the DRUJ is enhanced by ligaments and muscles, and The triangular fibro cartilage complex (TFCC) is the most important stabilizer. • In cases of volar dislocation, there is a history of hyper supination and the patient is unable to pronate. • In cases of volar dislocation, there is a history of hyper supination and the patient is unable to pronate.

              Missed isolated volar dislocation of distal radio-ulnar joint: a case report.

              We report a case of isolated volar dislocation of the distal radio-ulnar joint in a young man who injured his left wrist while playing rugby. Initially, this injury was missed in the emergency department; however, a true lateral view radiograph later revealed volar dislocation of the distal radio-ulnar joint. The dislocation was subsequently reduced under general anesthesia with a good end result. The importance of thorough clinical examination and a true lateral view radiograph of the wrist is stressed.
