本文对42具标本的腰骶韧带进行了研究。它从L5椎骨延伸到骶骨翼，并与其所连接的结构一起形成骨纤维化隧道，作为椎间孔的延伸。第五腰神经根穿过骶翼上方的隧道，位于LSL后方。第四腰神经根的一个分支在腰骶韧带前方与第五腰神经根在韧带下方汇合形成腰骶干。与L5神经根的交感交通支总是在LSL的上级边界处穿过LSL并到达隧道内的神经。髂腰血管的分支伴随L5根。通常发现L5下缘的大骨赘和LSL的紧密性导致L5神经根对骶骨翼的卡压和压迫。
The lumbo-sacral ligament (LSL) was studied in 42 specimens. It extends from the L5 vertebra to the ala of the sacrum and forms, with the structures to which it is attached, an osteofibrotic tunnel as an extension of the intervertebral foramen. The 5th lumbar nerve root passes through the tunnel over the ala of the sacrum and behind the LSL. A branch of the 4th lumbar nerve root passes in front of the LSL to join the 5th below the ligament to form the lumbo-sacral trunk. The sympathetic ramus communicans to the L5 root always penetrates the LSL at its superior border and reaches the nerve inside the tunnel. Branches of the ilio-lumbar vessels accompany the L5 root. Large osteophytes on the inferior border of L5 and tightness of the LSL were often found to cause entrapment and compression of the L5 nerve root against the ala of the sacrum.
