Trans-Scaphoid Transcapitate Perilunate Fracture-Dislocation.

Trans-scaphoid transcapitate (TSTC) perilunate fracture-dislocation (PLFD) is a rare type of perilunate injury. Because of the rarity and complexity of this entity, initial diagnosis may be delayed and the extent of osseous and ligamentous lesions underestimated. Early surgical treatment by open reduction and fracture stabilization is recommended to avoid complications such as avascular necrosis, nonunion, posttraumatic arthritis, and functional impairment. In this article, we report the case of a 32-year-old man who sustained a TSTC-PLFD. We describe the radiographic and intraoperative findings, review the current surgical principles for reduction and stabilization of this injury, and assess the clinical and radiologic outcomes.
