[Effectiveness of TiRobot-assisted and free-hand percutaneous kyphoplasty via pedicle of vertebra in treatment of osteoporotic vertebral compression fracture of thoracic vertebra].

To compare the effectiveness of TiRobot-assisted and C-arm X-ray fluoroscopy assisted percutaneous kyphoplasty (PKP) via pedicle of vertebra in the treatment of osteoporotic vertebral compression fracture (OVCF) of thoracic vertebrae. The clinical data of 85 patients with OVCF of thoracic vertebrae who were admitted between January 2020 and March 2023 and met the selection criteria was retrospectively analyzed including 40 patients (50 vertebrae) undergoing PKP assisted by TiRobot (group A) and 45 patients (50 vertebrae) undergoing PKP assisted by C-arm X-ray fluoroscopy (group B). There was no significant difference in the comparison of baseline data such as gender, age, body mass index, bone mineral density T-value, fracture segment, trauma history, and preoperative numerical rating scale (NRS) score, Oswestry disability index (ODI), and Cobb angle of injured vertebra between the two groups ( Both groups of patients successfully completed the operation, the operation time, the volume of injected cement, the times of fluoroscopies, and the length of hospital stay in group A were significantly less than those in group B ( TiRobot-assisted unilateral PKP in the treatment of OVCF of thoracic vertebrae is safe and effective, which can reduce the X-ray transmission times during operation, shorten the operation time, reduce the volume of bone cement injection, and thus decrease incidence of bone cement leakage. 比较“天玑”骨科机器人辅助下与C臂X线机透视下徒手经椎弓根行经皮椎体后凸成形术（percutaneous kyphoplasty，PKP）治疗胸椎骨质疏松性椎体压缩骨折（osteoporotic vertebral compression fracture，OVCF）的疗效。. 回顾分析2020年1月—2023年3月收治且符合选择标准的85例胸椎OVCF患者临床资料，其中40例（50个椎体）于“天玑”骨科机器人辅助下穿刺行PKP（A组），45例（50个椎体）于C臂X线机透视下徒手穿刺行PKP（B组）。两组患者性别、年龄、身体质量指数、骨密度T值、骨折节段、外伤史及术前数字疼痛评分（NRS）、Oswestry功能障碍指数（ODI）、伤椎Cobb角等基线资料比较差异均无统计学意义（ 两组患者均顺利完成手术，A组手术时间、骨水泥用量、透射次数及住院时间均少于B组（ “天玑”骨科机器人辅助下经椎弓根行PKP治疗胸椎OVCF安全有效，可减少术中透射次数、缩短手术时间、减少骨水泥注入量、降低骨水泥渗漏发生。.
