DISLOCATION of the scaphoid is a rare injury of which only a few reports of its occurrence appear in the literature. These include Higgs (1930), two cases; Buzby (1934); Kuth (1939); Wood-Walker (1943); Schlossbach (1954) and Connell & Dyson (1955), all reporting single cases. Russell (1949), in a review of intercarpal dislocations and fracture dislocations reported only one case of dislocation...

Trans-scaphoid, trans-radial styloid, trans-triquetral perilunate fracture dislocations are rare. We describe a 19-year-old male who suffered this injury after crashing his bicycle. He underwent open reduction internal fixation and percutaneous pinning. Scaphoid union was achieved at 8 weeks. Near complete range of painless motion was achieved by 4 months.

Scaphoid fracture with ipsilateral metacarpal fracture dislocation is very rare. A unique case of this injury is reported. It is important to be aware of this fracture pattern so that appropriate evaluation and treatment can be instituted. Thorough clinical and radiographic examination at the initial presentation of the patient is the key to identify uncommon combination of injuries.

A rare case of trans-radial styloid, trans-scaphoid, trans-triquetral perilunate dislocation is described. The injury was treated by reduction and internal fixation using a Herbert screw and Kirschner wire. A good functional result was achieved. A review of the literature illustrates that early surgery is recommended. Alternative surgical approaches are discussed.

We report a rare case of simultaneous dorsal dislocation of 4 ulnar carpometacarpal joints and dorsoradial dislocation of the trapezium with an associated fracture of the scaphoid tuberosity. The injuries were diagnosed early and treated successfully with closed reduction and transfixation using Kirschner wires. The functional results were excellent at 17-month follow-up.

AbsractAll perilunate fracture-dislocations combine bone avulsions, ligament disruptionand fractures in different forms. The most frequent pattern is the dorsal transscaphoidperilunate fracture-dislocation. The reported risk of missed initial diagnosisin perilunate dislocations is as high as 20%. Concerning pathomechanics of theperilunate fracture-dislocation, it should be noted that most dorsa...

A rare combination of an ulnar fracture with posterior dislocation of the head of the radius and fracture of the radius shaft concomitant with an ipsilateral scaphoid fracture is presented. To the best of our knowledge, no such case has been reported. The mechanism of this fracture combination is discussed with respect to its role in producing the Monteggia type II fracture. Treatment consisted...
