Isolated dislocation of the radial head, with simultaneous dislocation of proximal and distal radio-ulnar joints without fracture in an adult patient: case report and review of the literature

Simultaneous Dislocation of Proximal and Distal Radio-Ulnar Joints: A Case Report

“…2 Two others involved double volar dislocations of the proximal and distal radio-ulnar joints, and a criss-cross injury mechanism was proposed, with the interosseous membrane acting as a pivot between the 2 forearm bones. 3,4 In the current case, the radial head displaced anterolaterally and the ulnar head displaced dorsally. Continued hyperpronation may have been the main force to dislocate the proximal and distal radio-ulnar joints.…”

“…Four cases of simultaneous dislocation of the proximal and distal radio-ulnar joints have been reported. [1][2][3][4] One was a dislocation of the radial head and distal radio-ulnar joint associated with complete elbow dislocation. 1 Another was a 12-year-old injury, with instability of the elbow and wrist joints (injury mechanism was not described).…”

Simultaneous dislocation of the proximal and distal radioulnar joints

“…1,4,9,10,15 Both of these injuries occurring together in the same arm in an adult, after trauma, is an extremely rare event and we have identified only two cases reported in the English literature. 11,14 The humeroulnar joint and the radiocarpal joint are not affected in this injury. Other reports included either neglected chronic instability of the distal radioulnar joint or distal radioulnar joint dislocation associated with elbow dislocation.…”

Simultaneous dislocation of the radial head and distal radio-ulnar joint. A case report

“…A simultaneous dislocation of the radial head and distal radio-ulnar joint with no other injury seems to be extremely rare since only one report was found in the English literature 7.…”

“…Isolated dislocation of the DRUJ, although it has been described since 1777 by Desault 6, only few cases have been reported according to a recent review 7. Isolated dislocation of the radial head is common in children but rare in adults as only 20 cases have been reported during the last 30 years 8.…”
