Preliminary cadaver, animal, and human studies were performed to determine the feasibility of axial anterior lumbosacral spine access using a percutaneous, presacral approach. Custom instruments were directed under fluoroscopic guidance along the midline of the anterior sacrum to the surface of the sacral promontory where an axial bore was created into the lower lumbar vertebral bodies and discs. Imaging and gross dissection were performed in cadavers and animals. The procedure was used for lumbosacral biopsy in human subjects guided by intraoperative imaging and clinical monitoring. All procedures were technically successful. This study demonstrates the feasibility of the axial access technique to the anterior lower lumbar spine.
进行了初步的尸体、动物和人体研究，以确定采用经皮骶前入路进行腰骶椎前路轴向穿刺的可行性。在荧光透视引导下，使用定制器械沿骶骨前部中线指向骶岬表面，在该位置向腰椎椎体和椎间盘钻一个轴向孔。在尸体和动物身上进行了影像学和大体解剖。该手术在术中影像学和临床监测的引导下用于人体腰骶部活检。所有手术在技术上均获成功。本研究证明了轴向穿刺技术用于下腰椎前路的可行性。
