对 34 具尸体的腰骶椎椎间孔外韧带进行了研究。体横韧带附着在与躯体横突相同的椎骨上。在旋转半脱位或椎间盘空间完全丧失时，韧带可能会卡住其下方的退出神经根。腰骶韧带从L5横突和L5-S1椎间盘延伸至骶翼，形成L5脊神经穿过的腰骶隧道的顶部。如果还存在侧椎间盘突出、骨赘或肿瘤转移，这可能是椎间孔外卡压的部位。神经悬韧带附着在神经鞘和椎间盘上，被认为是机械感受的重要载体。
The extraforaminal ligaments of the lumbosacral spine were studied in 34 cadavers. The corporotransverse ligament attached to the body and transverse process of the same vertebra. The ligament may entrap the exiting nerve root below it in rotary subluxation or in complete disk space loss. The lumbosacral ligament extends from the transverse process of L5 and the L5-S1 disk to the sacral ala, forming the roof of the lumbosacral tunnel through which the L5 spinal nerve passes. This may be the site of extraforaminal entrapment if lateral disk herniations, osteophytes, or tumor metastasis are also present. The nerve suspensory ligament attaches to the nerve sheath and to the disk and is felt to be significant as a vehicle for mechanoreception.
