Frontal
Lateral
- loss of Gilula arcs
- proximal migration of capitate
- capitate not sitting within the distal articular 'cup' of the lunate
- a line drawn through radius and lunate fails to intersect capitate
- lunate remains in articulation with distal radius (as opposed to lunate dislocation where it is usually in a volar position)
-
piece of pie sign: although also seen in lunate dislocation it may prove very helpful in initial identification of lunate related pathology
