To evaluate the efficacy and safety of percutaneous tenotomy of the iliopsoas muscle tendon guided by ultrasound (US) in cadavers. We conducted an anatomical and descriptive study of the US-guided percutaneous tenotomy technique for the iliopsoas muscle tendon to review our experience performing it and its reproducibility in the clinical practice. Of the 20 tenotomies, 17 were total, at the level of the upper edge of the acetabulum, while 3 were partial. One procedure resulted in a partial injury to the femoral nerve. We measured the distance between the place of blade introduction and the femoral nerve, a noble structure potentially at a higher risk during the procedure; the mean distance was of 8.4 mm. Iliopsoas tendon release procedures guided by US in a cadaveric model are feasible and consistently result in the total release of the tendon, except in cases of obesity, with minimal repercussions on adjacent structures, and their completion requires approximately 4 minutes.
评估超声（US）引导下经皮髂腰肌肌腱切断术在尸体中的有效性和安全性。
我们对超声引导下经皮髂腰肌肌腱切断术进行了一项解剖学和描述性研究，以回顾我们实施该手术的经验及其在临床实践中的可重复性。
在20例肌腱切断术中，17例为在髋臼上缘水平的完全切断，3例为部分切断。1例手术导致股神经部分损伤。我们测量了刀片插入部位与股神经（该手术过程中潜在风险较高的重要结构）之间的距离；平均距离为8.4毫米。
在尸体模型中，超声引导下的髂腰肌肌腱松解手术是可行的，除肥胖病例外，通常能实现肌腱的完全松解，对相邻结构的影响最小，完成该手术大约需要4分钟。
