Late Distal Radio-Ulnar Joint Instability after Childhood Distal Forearm Fracture

Introduction: Paediatric distal radius fractures are considered benign, and associated ulnar styloid injury is mostly ignored. Although a significant portion evolves to non-union, only a minority present associated complications such as ulnar pain, ulnocarpal abutment, or distal radio-ulnar instability. Distal radio-ulnar dislocations are rare and point to failure of the stabilizing mechanisms of this joint, warranting urgent reduction. Case Report: 18-years old male presents to the emergency department with a volar distal radio-ulnar joint dislocation after a twisting motion of the left wrist. Patient was submitted to urgent closed reduction under general anesthesia and cast immobilization, and surgical repair of ulnar styloid non-union and triangular fibrocartilage complex tear was performed 1 week later. At 6 months follow up the patient as achieved pain free full mobility without instability. Conclusion: The triangular fibrocartilage complex and distal radio-ulnar joint may be affected by seemingly benign injuries, later presenting with acute complications. Fracture and subsequent non-union of the ulnar styloid in the setting of a distal radius fracture is common and underdiagnosed, but clinical significance of and optimal treatment of this injury are still undefined.

Isolated Volar Distal Radioulnar Joint Dislocation, a Very Rare and Easily Missed Injury.

Background: Isolated distal radioulnar joint (DRUJ) dislocations without associated fracture are very rare entities. A few mechanisms of injury were reported in the literature with dorsal(posterior) dislocation being more common than the volar (palmar, anterior) dislocation.
 Case report: A 26-year-old male, manual laborer presented to our emergency department (ED) 24 hours post-self-inflected injury with right wrist pain, deformity, and decreased range of motion (ROM). The physical examination showed bruising over the dorsal ulnar side of the wrist, loss of the ulnar styloid bony prominence, abnormal volar fullness of the wrist, and gutter deformity on the dorsal aspect of the distal forearm and wrist. The diagnosis was confirmed by comparative radiographs which were followed by closed reduction and immobilization in the below-elbow cast in pronation for 4 weeks.
 Conclusion: Timely accurate diagnosis and conservative treatment with favorable outcome necessitate a proper history on the mechanism of injury with a thorough physical examination, accurate radiographic positioning, and true lateral view.

A RARE COMBINATION: LOCKED VOLAR DISTAL RADIO-ULNAR JOINT DISLOCATION WITH ISOLATED VOLAR CAPSULE RUPTURE

Distal Radioulnar Joint (DRUJ) dislocation is a commonly missed injury. A high clinical suspicion is required as the dislocation may not be obvious in the conventional views of radiographs. Volar DRUJ dislocations are far less common than the dorsal ones. Since triangular fibrocartilage complex (TFCC) is the major stabilizer of DRUJ, it is common that the irreducible DRUJ dislocation is associated with TFCC tear. We report a patient who had irreducible volar DRUJ dislocation blocked by the volar lip of sigmoid notch, with only isolated volar capsule rupture.

Fracture de Galeazzi avec luxation radio-ulnaire palmaire

The authors report the rare case of Galeazzi fracture with a volar distal radio-ulnar joint dislocation, as it is very important to restore exactly the anatomy with solid fixation of the radius fracture to achieve reduction of the ulnar head.

Complex volar dislocation of the distal radioulnar joint in a Galleazi variant associated with interposition of the ulnar neurovascular bundle

Galleazi type fracture dislocations are sometimes associated with complex dorsal dislocation of the distal radioulnar joint due to interposition of the extensor carpi ulnaris tendon. We present the first reported case of complex volar distal radioulnar joint dislocation in a Galleazi variant associated with interposition of the ulnar neurovascular bundle.
