Radial trans-scaphoid perilunate dislocation.

An unusual case of trans-scaphoid perilunate fracture-dislocation of the carpus with radial displacement in a 19-year-old man is reported. On the basis of the clinical and radiologic findings it was assumed that the tip of the radial styloid process caused the scaphoid fracture. Following closed reduction with acceptable positioning of the carpal bones, the patient has good function and slight pain, and was able to return to almost full employment about 1 year postinjury.
