Abstract
A rare case of trans-triquetral dorsal perilunate dislocation is described. It differs from the Mayfield and Johnson theory of progressive perilunar instability in greater arc injuries which states that the injury passes from the radial to the ulnar carpal bones and soft tissues in stages. This injury supports the concept of a reverse greater arc injury from ulnar to radial being possible with the radial carpal bones being spared in some cases.
