- ABSTRACT: Lunate dislocation is a palmar dislocation of the lunar bone caused by high–energy trauma such as falling from a motorcycle. It is a rare injury often misdiagnosed on initial examination. Median nerve paralysis or ischemic necrosis of the lunar bone may occur if not treated quickly. We report a case of lunate dislocation with distal radius fracture after a motorcycle accident. A 27–year–old man driving a motorcycle collided with a car and fell off. He complained of left wrist pain. Physical examination revealed no head or trunk trauma. He was diagnosed as having left lunate dislocation with distal radius fracture, right thumb metacarpal fracture and right capitate bone fracture by simple X–ray/CT examination. Open dislocation reduction and internal fixation were performed on the left wrist joint on the day of injury and on the right hand on the following day. He was discharged without complications on the ninth hospital day. The lunate dislocation was diagnosed and treated at an early stage, leading to a good outcome without complications. When diagnosing lunate dislocation, attention must be paid to the characteristic injury mechanism of severe wrist dorsiflexion and disorder of the carpal bone arrangement on simple X–ray images of the wrist joints. 要旨:ABSTRACT: Lunate dislocation is a palmar dislocation of the lunar bone caused by high–energy trauma such as falling from a motorcycle.
