Introduction

Fracture-dislocations of the carpus represent a spectrum of complex injuries1-3,5-12,14. Accurate description of a specific injury may be difficult because of the number of skeletal and ligamentous structures involved. Some authors have suggested that these injuries represent so-called perilunate injuries, as the mechanism of injury has been noted to follow a pattern about the lunate5,9,10. Moneim described greater arc injuries as those including trans-scaphoid, transcapitate, trans-hamate, and transtriquetral perilunate fracture-dislocations. When the lunate itself is dislocated, the injury is more extensive and classification is more difficult.
We report the case of a patient who had an unusual fracture-dislocation of the wrist. The lunate was displaced volarly in conjunction with displaced fractures of the adjacent scaphoid and triquetrum.
