Eighteen cadaveric dissections were performed to determine the location of the segmental vessels and the cephalad nerve root in relation to the posterolateral lumbar disc. The most lateral point of each lumbar disc was determined, and measurements were made form this reference point. Segmental vessels were found to be a mean of 10 to 13 mm from the junction of the vertebral body and the disc. The exception to this was the vessel superior to L5-S1, which was a mean of 7 mm from the disc margin. The cephalad nerve roots were consistently found to be adjacent to the disc, and were an average of 9 to 22 mm posterior to the lateral reference point.
进行了18次尸体解剖，以确定节段血管和向头侧走行的神经根相对于腰椎间盘后外侧的位置。确定了每个腰椎间盘的最外侧点，并从该参考点进行测量。发现节段血管距椎体与椎间盘的交界处平均为10至13毫米。L5-S1上方的血管除外，其距椎间盘边缘平均为7毫米。一直发现向头侧走行的神经根与椎间盘相邻，且位于外侧参考点后方平均9至22毫米处。
