Abstract: Fractures of lunate bone are rare injuries of the wrist that are usually resulted from high-energy trauma and are typically accompanied by other carpal injuries, such as scaphoid bone, capitate bone, radial styloid, and distal radius fracture. Misdiagnosis,missed diagnosis or inappropriate treatment in clinical practice lead to a high nonunion rate of lunate fractures, which often affects the movement of the wrist and even leads to complications such as osteonecrosis or loss of wrist function. The potential pathogenesis, therapeutic method,and prognosis of lunate fractures are still controversial. This article reviewed domestic and foreign literature on the classification, imaging characteristics and treatment methods from the perspectives of anatomical characteristics and injury mechanism of the lunate, so as to provide guidance for improving the prognosis of lunate fractures.

Key words: Lunate bone, Fracture nonunion, Osteonecrosis, Carpal injury
