Bifocal dislocation of the forearm: elbow and perilunate dislocation

We report a case of bifocal dislocation of the forearm due to posterior dis location of the elbow and transcaphocapital retrolunate dislocation of the carpus, Fenton's syndrome, associated with fracture of both bones of the fo rearm. The emergency procedure achieved reduction of the elbow, plate fixat ion of the radius and ulna, used a posterior and an anterior access to achi eve reduction and osteosynthesis of the radial styloid, the scaphoid, and t he capitatum and temporary schapholunate, triquetrolunate, scaphocapitate, and radiolunate pinning. At ten months, the patient only complained of mode rate pain for exceptional efforts. Complete amplitude elbow motion was rest ored. Wrist flexion and extension were 50 degrees and 30 degrees respective ly. X-rays demonstrated union of the scaphoid and the capitatum. There was no scapholunate diastasis and the scapholunate angle was normal.
