Clinical outcomes in arthroscopic hip preservation surgery have improved over the past two decades due to many factors, including advancements in technique and instrumentation. Complications following hip arthroscopy are associated with increased traction and overall surgical times. The purpose of this study was to compare traction and surgical times during hip arthroscopy using two different radiofrequency ablation wands produced by the same manufacturer. The authors hypothesized that the wand with a larger surface area would result in significantly less traction and surgical times. This study was a retrospective comparative investigation on patients who underwent arthroscopic surgery of the central, peripheral, peritrochanteric and/or deep gluteal space compartments of the hip. Both wands are 50-degree-angled probes, but the tip and shaft diameters are 3 and 3.75 mm for Wand A (Ambient Super MultiVac 50; tip surface area 7.1 mm2) compared to 4.7 and 4.7 mm for Wand B (Ambient HipVac 50; tip surface area 17.3 mm2), respectively. There was no difference (P = 0.16) in mean age of Wand A patients (30 females, 20 males; 35.2 years) versus Wand B patients (31 females, 19 males; 32.7 years). Traction time was significantly less in the Wand B group (41 ± 6 versus 51 ± 18 min; P < 0.001), as was surgical time (102 ± 13 versus 118 ± 17 min; P < 0.001). There were no significant differences in the number of labral anchors used or Current Procedural Terminology codes performed between groups. In conclusion, it was observed that the use of a larger surface area wand was associated with significantly less traction and surgical times during hip arthroscopy.

在髋关节镜检查中在双极射频棒上使用更大表面积的尖端与显着降低牵引力和总手术时间相关

由于许多因素，包括技术和器械的进步，关节镜下髋关节保留手术的临床结果在过去 20 年有所改善。髋关节镜检查后的并发症与牵引力增加和整体手术时间有关。本研究的目的是比较使用同一制造商生产的两种不同射频消融棒进行髋关节镜检查时的牵引和手术时间。作者假设具有较大表面积的魔杖会导致牵引和手术时间显着减少。这项研究是一项回顾性比较研究，对接受髋关节中央、外周、转子周围和/或臀部深部空间隔室的关节镜手术的患者进行。两根棒都是 50 度角探头，但 Wand A（Ambient Super MultiVac 50；尖端表面积 7.1 mm2）的尖端和轴直径分别为 3 和 3.75 mm，而 Wand B（Ambient HipVac 50；尖端表面积 17.3 mm2）分别为 4.7 和 4.7 mm。Wand A 患者（30 名女性，20 名男性；35.2 岁）与 Wand B 患者（31 名女性，19 名男性；32.7 岁）的平均年龄没有差异（P = 0.16）。Wand B 组的牵引时间显着缩短（41 ± 6 对 51 ± 18 分钟；P < 0.001），手术时间也是如此（102 ± 13 对 118 ± 17 分钟；P < 0.001）。组间使用的盂唇锚的数量或执行的当前程序术语代码没有显着差异。总之，据观察，在髋关节镜检查期间，使用更大表面积的棒与显着减少牵引和手术时间相关。
