Isolated volar dislocation of the distal radioulnar joint: Current concepts review and case report

Isolated volar distal radioulnar joint (DRUJ) dislocation is a rare condition with only a few cases reported in the literature. Its diagnosis is often overlooked in the acute phase, and there is no consensus in its management. We present the case of a 20-year-old male patient with an isolated volar radioulnar dislocation, together with a review of the literature. The aim is to present and summarize the acute management of this condition and propose a therapeutic algorithm.

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.

Outcomes of Isolated Radial Osteotomy for Volar Distal Radioulnar Joint Instability Following Radial Malunion in Children.

The radius bone has a slight dorsoradial bow that allows for full forearm pronosupination around the ulna. However, radial malunion can lead to reversal of the radial bowandsubsequent volar instability of the distal radioulnar joint (DRUJ), predominantly in supination. This study assessed the outcomes of corrective radial osteotomy for volar DRUJ instability after radial malunion in children. The charts of 7 children (2 boys and 5 girls) treated with corrective radial osteotomy for volar DRUJ instability after a radius fracture or deformity were reviewed. Demographic, diagnostic, treatment, and complication information was collected for each patient. Radiographs at initial injury, fracture union, diagnosis of DRUJ instability, and final follow-up were reviewed for radiographic measurements of radial deformity and subsequent correction. Fractures included 4 distal radius, 2 proximal radius, and 1 plastic deformation of the radial shaft. Volar DRUJ instability was diagnosed an average of 2.7 years (range, 1-6 years) after fracture at an average age of 13.6 years (range, 12-17 years). Two of 7 patients hadpersistent symptoms despite having undergone previous soft tissue surgery for DRUJ instability. Radial osteotomy was performed on all patients (3 dorsal and 4 volar approaches), with an average sagittal plane correction of 23° ± 10° (range, 14° to 40°). Osteotomy site varied (3proximal third, 1 middle third, and 3 distal third) based on the apex of maximal deformity. Patients were observed an average of 2.3 years (range, 1.0-5.7 years). At final follow-up, all patients had a stable DRUJ and no patient required soft tissue stabilization. Apex volar malunion of radial fractures may result in volar instability of the DRUJ. Radial osteotomy restored the normal apex dorsal radial bow and effectively stabilized the DRUJ without the need for soft tissue repair. Osteotomy should be tailored to the specific site of radiographic deformity. Therapeutic V.

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.

Luxation radio-cubitale palmaire, cas clinique et revue de la littérature

The authors report the case of a volar distal radio ulnar joint dislocation. The rarity of this lesion seems to be linked to the anatomical relationship of the distal portion of the ulna with the tendons of the extensor carpi ulnaris and the tendon of the extensor digiti minimi. Early diagnosis based on physical examination and radiology gives a better prognosis for closed treatment, reserving surgery for failure or irreducible luxations.
