Dorsal perilunar dislocations are rare traumatic entities. Associated fractures such as carpal bones and radial styloid processes can occur. However, the dorsal perilunar dislocation associated with dislocation of distal radioulnar joint is extremely rare. The authors herein report the case of a 34-year-old man who was presented with transscaphoidal perilunar dislocation which is associated with dislocation of distal radioulnar joint.
The authors report the case of a patient with the combination of a Type I Monteggia equivalent lesion and Essex-Lopresti injury. This combination of injury is very rare, and an associated distal radioulnar injury is often missed. We hope our experience illustrates the need to examine the wrist joint carefully and to be aware of the potential for distal radioulnar joint instability in all patients with type I Monteggia equivalent lesions.
There are variable types in wrist joint injury. Most common case is simple distal radius fracture. And ulnar head dislocation associated with disruption of distal radioulnar ligament is unusual. Among thease injury types. volar dislocation of ulnar head in the distal radioulnar joint is not common and it is misdiagnosis frequently. So it needs to surgical operation frequently. The author reviews this injury with the relevant literature.
PURPOSE To evaluate the significance of distal radioulnar joint injury which may affect the postoperative radiologic and clinical results of AO classification, type C distal radius fractures. MATERIALS AND METHODS From October 2000 to October 2005, 58 patients of AO classification, type C distal radius fracture, who had been treated with operative methods were studied. They are thirty-six men and twenty-two women. The average follow up period was 14 months. The patients were divided into five groups. In the first group (13 cases), there was no distal radioulnar joint injuries. In the second group (20 cases), there were ulnar styloid fractures. In the third group (11 cases), there were separation of distal radioulnar joint. In the fourth group (9 cases), there were ulnar styloid fractures with separation of distal radioulnar joint. In the fifth group (5 cases), there were displacement of ulna in sagittal plane. We measured the radial length, radial inclination and volar tilt in plain radiograph in each group and analyzed the results through Scheck's methods. To analyzed the clinical results, we used the Demerit Point System by Sarmiento. RESULTS There was no significant differences in radiologic and clinical results among the five groups. CONCLUSION According to compairing the radiologic results of each group which was suspicious of distal radioulnar joint injuries, in the intraarticular comminuted fractures of distal radius, the distal radioulnar joint injuries did not affect the results of treatment when anatomical reduction of distal radius was achieved.

PURPOSE To evaluate the effectiveness of operative treatment in distal radius fracture with distal radioulnar joint injury.
MATERIAL AND METHOD: From January 1992 to January 2000, 66 cases of distal radius fracture with distal radioulnar joint injury who had been treated with conservative or operative methods were analyzed the final state of radius articular surface and distal radioulnar joint. RESULT In operatively treated cases(42 cases), the average of volar tilt was 3.74 degrees, ulnar inclination 21.9 degrees, radial length 9.74mm. In conservatively treated cases(24 cases), The average of volar tilt was 1.75 degrees, ulnar inclination 15.1 degrees, radial length 7.67mm. The state of distal radioulnar joints were as follows; In operatively treated cases, anatomical reduction 37(88%), joint widening 5, In conservatively treated cases, anatomical reduction 17(70%), joint widening or ulnar impingement syndrome 7. CONCLUSION In treatment of distal radius fracture with distal radioulnar injury, operative treatment is probably more effective in restoration of radius articular surface and distal radioulnar joint healing.
