Trans-scaphoid trans-triquetrum lunate dorsal dislocation combined with fracture of ulnar and radius with forearm compartment syndrome: a case report.

We reported a case of a 45-year-old male patient with trans-scaphoid trans-triquetrum lunate dorsal dislocation combined with fracture of ulnar and radius with forearm compartment syndrome. During the initial surgery, the scaphoid fracture end was mistakenly fixed together with the triquetrum fracture end, leading to an erroneous reduction, which was later identified and corrected through a secondary reduction. It is emphasized that in patients with lunate dislocation and concomitant scaphoid and triquetrum fractures, accurate identification of the fracture ends of both the scaphoid and triquetrum bones is critical to avoid erroneous fixation. Furthermore, the presence of ulnar and radial fractures increases the risk of forearm compartment syndrome.
