Carpus - Perilunate, dissociation

General considerations

Perilunate dislocations are pure ligamentous injuries. They result from high-energy trauma. They may lead to severe disruption of carpal anatomy, leading to profound changes in wrist biomechanics.

Rupture of the scapholunate ligament is the first event in any sequence of perilunar ligament ruptures. It is the most common cause of wrist instability.
