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.
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).
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.
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.
探讨术前规划及虚拟手术（包括手术开窗和抬高复位）的应用，并确定该技术对Schatzker III型胫骨平台骨折治疗的临床效果。
采用密封信封法对32例Schatzker III型胫骨平台骨折患者入院时进行随机分组。14例采用术前虚拟设计及辅助手术治疗（虚拟组），18例采用直接切开复位内固定治疗（对照组）。
所有患者切口均一期愈合。与对照组相比，虚拟组在手术时间、切口长度和出血量方面具有显著优势（P < 0.001）。虚拟手术与实际手术相符。
虚拟组在治疗Schatzker III型胫骨平台骨折方面优于对照组，手术时间更短，切口长度更小，出血量更少。重建的三维骨折模型可用于术前确定手术开窗和抬高复位方法，并模拟Schatzker III型胫骨平台骨折的手术。
