Staging of scapholunate dissociations as proposed by Garcia-Elias et al [5]

Scapholunate dissociation stage	Anatomopathological abnormality
1	Is there a partial rupture with a normal dorsal scapholunate ligament?
2	If ruptured, can the dorsal scapholunate ligament be repaired?
3	Is the scaphoid normally aligned (radioscaphoid angle ≤ 45°)?
4	Is the carpal malalignment easily reducible?
5	Are the cartilages at both radiocarpal and midcarpal joints normal?
6	Complete scapholunate ligament injury with irreducible malalignment and cartilage degeneration?
