Suture Anchor Fixation for Lunate Osteochondral Shear Fracture

Abstract

Case: A 26-year-old right-hand–dominant man sustained a left transradial, translunate perilunate injury after motor vehicle collision. The proximal lunate fractured a primarily cartilaginous 15 × 15 mm osteochondral shear fragment with 40% articular surface involvement. A novel lunate fracture suture anchor fixation technique is described, which led to fracture healing. The radial styloid was treated with a single screw. Conclusion: Translunate perilunate injuries involving the lunate proximal articular surface are rare. Treatment recommendations are limited to case reports. Suture anchor fixation led to stable fixation and fracture healing at the final 6-month postoperative follow-up.
