Abstract

Isolated dorsal dislocation of the trapezoid at the scaphotrapeziotrapezoidal (STT) joint represents an exceptionally rare entity among carpal injuries. This report documents the case of an adult male who sustained an injury in a high-energy road traffic accident and presented with wrist pain, swelling, and deformity. Radiographs and computed tomography confirmed a dorsal dislocation of the trapezoid at the STT joint without associated perilunate disruption or carpal fractures. The injury was successfully managed with closed reduction and splint immobilization. At the short-term follow-up, the patient demonstrated anatomic alignment, full recovery of wrist function, and completely pain-free movement. This case highlights the importance of maintaining a high index of suspicion and utilizing advanced imaging to ensure early recognition and optimal treatment of this rare carpal injury.
