We examined 40 wrists of 12 embalmed and eight fresh cadavers and defined the relative position of the flexor retinaculum to the neurovascular structure, ultrasonographic markers and safe zones by ultrasonography and anatomical dissection. Both longitudinal and transverse ultrasonographic sections clearly depicted the flexor retinaculum, neurovascular bundles, median nerve, flexor tendons and bony boundaries of the underlying joints. Topographic measurement showed [i] good correlation between the actual extent of the flexor retinaculum and the ultrasonographically determined distance between bony landmarks in all hands, and [ii] the widths and lengths of well-defined safe zones. A comparison study confirmed the accuracy of ultrasonography. We conclude that these ultrasonographic landmarks can locate the flexor retinaculum and facilitate safe and complete carpal tunnel release with open or minimally invasive techniques.
我们检查了12具防腐处理尸体和8具新鲜尸体的40只手腕，通过超声检查和解剖确定了屈肌支持带相对于神经血管结构、超声标志物和安全区的相对位置。纵向和横向超声切面均清晰显示了屈肌支持带、神经血管束、正中神经、屈肌腱以及下方关节的骨性边界。局部测量显示：[i] 所有手部中屈肌支持带的实际范围与超声测定的骨性标志之间的距离具有良好相关性；[ii] 明确的安全区的宽度和长度。一项对比研究证实了超声检查的准确性。我们得出结论，这些超声标志物可定位屈肌支持带，并有助于采用开放或微创技术安全、完整地进行腕管松解术。
