使用带针的套索环缝合进行关节镜下肩胛下肌修复的改良单工作门静脉技术
2025年8月8日
我们提出了一种改进的关节镜技术，即使用针通线套索环通过单侧前门静脉缝合肩胛下骨。
本研究的重点是关节镜手术技术，旨在改进方法，使手术更简单、更有效。传统的肩关节镜检查通常需要前门柱和后门柱。然而，最近的发展引入了更简单、侵入性更小的单门静脉技术。
尽管这些方法可能会给缝合线管理带来挑战，并可能增加创伤。该协议显着简化了作。而且，少一环缝合线更稳定，无需使用其他耗材即可降低成本，增加作效益。
首先，通过在患者肩部区域创建的后门脉确定肩胛下撕裂的上三分之一。松开肩胛下肌腱覆盖小结节，新鲜小结节诱出血。然后将双负载锚植入肩胛下足迹中。
将针头插入前门的撕裂处。调整循环大小并慢慢退出。接下来，用抓具从前门柱拉出PDS线环和一根白色和蓝色锚缝线，并在体外将两根锚缝线完全穿过PDS线环。
然后，拉动 PDS 环以穿过锚缝线的中间部分，并在肩胛下肌中形成缝合环。将缝合线的自由端穿过这个缝合环并将其拉紧以形成肩胛下肌的自收紧针迹。不要收紧自收紧针迹，否则会使肩胛下肌远离较小的结节足迹。
然后，拧紧锚缝线的另一端，将肩胛下肌固定到小结节上。最后，抓住白色和蓝色锚缝线的两端，依次打扎固定。该手术对 18 名患者进行了检查，并在术后对他们进行了评估。
与术前值相比，使用视觉模拟量表测量的疼痛在术后 12 个月显着减轻。与术前值相比，术后 12 个月，通过 Constant-Murley 评分和美国肩肘外科医生评分评估的肩部功能和功能结果显着改善。与术前测量值相比，术后 12 个月的肩屈曲、外旋和 90 度外展时的内旋显着增加。
