title: Partial necrosis of the lunate after a translunate palmar perilunate fracture dislocation.
abstract: We present an extreme rare case of traumatic partial avascular necrosis of the lunate after palmar perilunate dislocation with lunate fracture. A 32-year-old female was injured by motorcycle accident with palmar perilunate fracture dislocation and lunate fracture. Scapholunate and lunotriquetrum dislocations were reduced and fixed temporarily. The torn dorsal ligament was repaired. Considering close observation with both arthroscopy and fluoroscopy, we decided not to conduct open reduction and internal fixation for the lunate. Partial avascular necrosis of the lunate appeared gradually in follow-up.
