Lateral femoral cutaneous nerve (LFCN) decompression and transposition are surgical treatment options for meralgia paresthetica. Identifying the LFCN during surgery may be challenging, and preoperative localization is a valuable adjunct in this case. The objective of this study was to explore a new technique using preoperative ultrasound-guided clip localization (USCL) of the LFCN.
After Institutional Review Board approval, data were collected on patients who underwent both preoperative ultrasound-guided wire localization (USWL) and USCL over the past 13 years. Skin-to-nerve time was calculated prospectively.
Fifty-six patients were identified, 51 had USWL and 5 had USCL; the skin-to-nerve median time was 7.5 and 6 minutes, respectively. Six wires were misplaced, and this was at the beginning of utilization of the USWL technique. There were no nerve injury, infection, or bleeding complications related to either wire or clip placement.
USWL or USCL is safe and time-efficient in LFCN surgeries.
股外侧皮神经（LFCN）减压术和转位术是感觉异常性股痛的手术治疗选择。手术中识别LFCN可能具有挑战性，在此情况下术前定位是一项有价值的辅助手段。本研究的目的是探索一种使用术前超声引导下LFCN夹定位（USCL）的新技术。
经机构审查委员会批准后，收集了过去13年中接受术前超声引导下钢丝定位（USWL）和USCL的患者的数据。前瞻性计算皮肤到神经的时间。
共识别出56例患者，51例行USWL，5例行USCL；皮肤到神经的中位时间分别为7.5分钟和6分钟。6根钢丝放置错误，这发生在USWL技术使用初期。未出现与钢丝或夹子放置相关的神经损伤、感染或出血并发症。
USWL或USCL在LFCN手术中安全且高效。
