强直性脊柱炎(AnkylosingSpondylitis,AS)是一种慢性炎症性疾病,主要累及脊柱并导致骨质结构改变,显著增加胸腰椎骨折风险{l。AS 相关胸腰椎骨折常伴有骨质疏松、骨结构破坏和脊柱畸形等复杂病理改变,治疗难度较大。椎弓根螺钉固定是主要治疗手段,其效果直接影响患者预后。传统徒手置钉技术依赖术者经验,易出现置钉偏差、固定强度不足等问题,可能导致螺钉松动、断裂或神经损伤等并发症[2。近年来,机器人辅助手术因其精准的定位和导航功能,逐渐应用于脊柱外科领域[3]。该技术有望提高AS合并胸腰椎骨折手术的螺钉置入精度,减少手术并发症。本研究旨在评估机器人辅助椎弓根螺钉内固定术治疗AS合并胸腰椎骨折的临床效果。
1 资料与方法
1.1临床资料选取2020年1月—2024年1月新疆医科大学第六附属医院收治的84例AS合并胸腰椎骨折患者,采用随机数表法分为对照组( n=42 )和观察组( n=42 )。对照组患者行手术机械臂或光学导航系统辅助徒手椎弓根螺钉内固定术,观察组患者行机器人辅助椎弓根螺钉内固定术。纳入标准:① 符合国际脊柱关节炎协会ASAS-2016关于AS的诊断标准[5]; ② 经CT三维重建确诊为急性胸腰椎骨折(AOSpine分型A/B型),累及T10~L2单节段;③ 术前美国脊柱损伤协会(American Spinal InjuryAssociation,ASIA)神经功能分级 ⩾D 级; ④ 无严重心肺功能障碍,能耐受手术。排除标准: ① 合并严重骨质疏松; ② 既往胸腰椎内固定手术史;③ 合并其他部位恶性肿瘤; ④ 对手术内固定材料过敏; ⑤ 合并精神性疾病,无法配合手术及术后康复训练。……
