Complete disruption of the lunate from both dorsal and palmar ligamentous attachments caused by palmar dislocation has rarely been reported. The authors present two cases and discuss the surgical treatments performed. They conclude from these cases that the lunate is at risk for remaining avascular after such trauma, so that proximal row carpectomy should be considered as a surgical option in the primary treatment.
