This case report describes a 74-year-old man with the rare injury of transscaphoid dorsal lunate dislocation (LD). He sustained a crushing injury with a huge amount of energy to his right wrist while working with a pressing machine. There were deep abrasions and areas of skin necrosis on the dorsum of the wrist. The patient was treated with closed reduction and a Herbert screw fixation for the scaphoid fracture. Six months postoperatively, avascular necrosis (AVN) of the lunate and scaphoid was apparent on the wrist radiographs. We offered a proximal row carpectomy to the patient, but he declined surgery because he was able to perform his activity of daily living. Dorsal LD as well as its variants has a high prevalence of AVN of the lunate. Delayed diagnosis, delayed treatment, and open reduction increase the risk of AVN development of the lunate. The level of evidence is therapeutic IV.

Article Synopsis
- Perilunate dislocation is a rare wrist injury often caused by excessive loading on a hyperextended and ulnar-deviated wrist, leading to potential ligament damage and displacement of the lunate bone.
- A unique case of a 38-year-old construction worker with a trans-styloid, trans-scaphoid perilunate fracture dislocation and accompanying carpal tunnel syndrome was documented, marking an unusual presentation not previously reported.
- Treatment involved open reduction and ligament repair to preserve hand function, along with carpal tunnel release due to the symptomatic nerve compression.
