The adductor canal block has become a common analgesic technique in patients undergoing knee arthroplasty. Dispersion of local anesthetic outside the adductor canal through interfascial layers and blockade of smaller nerves that confer innervation to the knee could contribute to the analgesic efficacy of the adductor canal block. We studied the diffusion of local anesthetic mixed with dye after injection into the adductor canal in fresh human cadavers. In all 8 legs, injectate was found in the popliteal fossa in contact with the sciatic nerve and/or popliteal blood vessels. Interfascial spread patterns were identified.
内收肌管阻滞已成为膝关节置换术患者常用的镇痛技术。局部麻醉药通过筋膜层扩散至内收肌管外，并阻断支配膝关节的较小神经，这可能有助于内收肌管阻滞的镇痛效果。我们研究了在新鲜人体尸体的内收肌管注射混有染料的局部麻醉药后的扩散情况。在所有8条腿中，均在腘窝发现注射物与坐骨神经和/或腘血管接触。确定了筋膜间的扩散模式。
