Publisher's Synopsis
Dislocations and perilunate fracture-luxations of the carpus are uncommon injuries, accounting for 5-10% of traumatic wrist injuries. The combination of bone and ligament injuries explains the difficulty of treating these injuries. We collated 30 retrolunate dislocations and fracture-luxations of the carpus surgically treated between 2004 and 2014 with a minimum follow-up of 24 months. Two classifications were used Herzberg's classification for perilunate dislocation fractures of the carpus, which comprises 3 stages I, IIa and IIb according to the direction of sagittal displacement of the capitate in relation to the lunate and the degree of sagittal displacement of the lunate in relation to the radius.
