研究目的:

评价足踝固定器在OWHTO中的应用价值,为 OWHTO 术中精确调整患侧下肢力线提供设备和技术支持,同时缩短手术时间、减少术中透视,降低患者及手术人员放射暴露风险,节约人力资源。  

Objectives of Study:

Evaluate the application value of the Foot & Ankle fixation device in OWHTO, provide equipment and technical support for precisely adjusting the force line of the affected lower limb during the OWHTO procedure, shorten the operation time, reduce intraoperative fluoroscopy, lower the radiation exposure risk for both patients and surgical personnel, and save human resources.
