Analysis for Clinical Effect of Virtual Windowing and Poking Reduction Treatment for Schatzker III Tibial Plateau Fracture Based on 3D CT Data

Objective. To explore the applications of preoperative planning and virtual surgery including surgical windowing and elevating reduction and to determine the clinical effects of this technology on the treatment of Schatzker type III tibial plateau fractures. Methods. 32 patients with Schatzker type III tibial plateau fractures were randomised upon their admission to the hospital using a sealed envelope method. Fourteen were treated with preoperative virtual design and assisted operation (virtual group) and 18 with direct open reduction and internal fixation (control group). Results. All patients achieved primary incision healing. Compared with control group, virtual groups showed significant advantages in operative time, incision length, and blood loss (P < 0.001). The virtual surgery was consistent with the actual surgery. Conclusion. The virtual group was better than control group in the treatment of tibial plateau fractures of Schatzker type III, due to shorter operative time, smaller incision length, and lower blood loss. The reconstructed 3D fracture model could be used to preoperatively determine the surgical windowing and elevating reduction method and simulate the operation for Schatzker type III tibial plateau fractures.
