The present study aimed to assess the efficacy and safety of ultrasound-guided percutaneous A1 pulley release using a needle knife.
The author performed percutaneous A1 pulley release in 84 cadaveric hands fixed with 10% formalin. The cadaveric hands were divided into three groups: 28 hands in each group (group U: ultrasound-guided needle knife pushing group, group N: non-ultrasound-guided needle knife pushing group, group T: classical needle knife operation puncture group). Percutaneous A1 pulley release was performed, the soft tissue was dissected layer by layer, and the relevant anatomical data were measured.
The injured cases were as follows: group U, 29 (20.7%); group N, 36 (25.7%); and group T, 28 (20.0%). There is no significant difference between different tissue injury types in different intervention methods. The missed release cases were as follows: group U, 8 (5.7%); group N, 4 (2.9%); and group T, 13 (9.3%). The percentage of released A1 pulley were as follows: group U, 71.4% ± 30.7%; group N, 66.0% ± 20.3%; and group T, 61.0% ± 30.4%. The percentage of released A1 pulley of the three groups were compared: group U > group N > group T, and there was statistical difference between the three groups. The full release rates of the three groups were compared: group U(31.4%) > group N(15.7%) > group T(13.6%), and there were significant difference in the full release of A1 pulley between group U and group T, group N.
Based on the cadaver specimen, the length and percentage of released A1 pulley is longer by ultrasound-guided percutaneous A1 pulley release using a needle-knife. and there was no statistical difference in the injury rate between the three techniques.
Clinical anatomic study. To test the efficacy and safety of ultrasound-guided percutaneous A1 pulley release using a needle knife in cadaveric hands, and provide an anatomically based support in clinic.
本研究旨在评估超声引导下使用针刀经皮松解A1滑车的疗效和安全性。
作者在84只用10%福尔马林固定的尸体手上进行经皮A1滑车松解。将尸体手分为三组：每组28只手（U组：超声引导针刀推进组，N组：非超声引导针刀推进组，T组：经典针刀手术穿刺组）。进行经皮A1滑车松解，逐层解剖软组织，并测量相关解剖数据。
损伤情况如下：U组29例（20.7%）；N组36例（25.7%）；T组28例（20.0%）。不同干预方法下不同组织损伤类型之间无显著差异。遗漏松解情况如下：U组8例（5.7%）；N组4例（2.9%）；T组13例（9.3%）。A1滑车松解百分比情况如下：U组71.4%±30.7%；N组66.0%±20.3%；T组61.0%±30.4%。比较三组A1滑车松解百分比：U组＞N组＞T组，三组间存在统计学差异。比较三组完全松解率：U组（31.4%）＞N组（15.7%）＞T组（13.6%），U组与T组、N组之间A1滑车完全松解存在显著差异。
基于尸体标本，超声引导下使用针刀经皮松解A1滑车的长度和松解百分比更长。三种技术之间的损伤率无统计学差异。
临床解剖学研究。旨在测试超声引导下使用针刀经皮松解尸体手A1滑车的疗效和安全性，并为临床提供解剖学依据支持。
