Diagnosis

Volar perilunar dislocation

Discussion

Frontal radiograph of the wrist reveals overlap of the distal carpal row with the proximal carpal row. This overriding gives rise to the “crowded carpal” appearance and is a sign specific for volar perilunate dislocation. It is secondary to proximal migration of the distal row of carpal bones during subluxation.
