Q
Order of ligaments injured in a perilunate dislocation using the Mayfield classification?
A
I - Scapholunate dissociation: Radioscaphocapitate and scapholunate ligaments fail
II - Lunocapitate dissociation: dorsal dislocation of the capitate
III - Lunotriquetral dissociation “perilunate”: lunotriquetral ligament fails
IV - Lunate dislocates from lunate fossa, risk of median n. compression: Dorsal radiocarpal ligament tear
Shor radiolunate ligament is the last ligament to remain intact.
