在３０具成人和５具新生儿（计７０侧）尸体脊柱腰骶段标本上，观察了腰５－骶１椎间孔区的三条韧带及其与邻近结构的毗邻关系。腰骶韧带和腰骶弓状筋膜恒定（１００％）；椎体横突韧带少见（４０．２９％±５．８６％），其坚韧，形似索状。第五腰神经前支在后者深面的下方穿出椎间孔，易被挤压而引发腰腿痛。
Three lumbosacral ligaments in the lumbosacral-lumbosacral foramen lumbar region and their adjacent structures were observed on the lumbosacral specimens of 30 adult and 5 neonatal (total 70) cadaveric spine. The lumbosacral ligament and lumbosacral fascia were constant (100%). The transverse ligament of vertebral body was rare (40.29% ± 5.86%), which was tough and cord-like. Fifth anterior lumbar nerve in the latter deep below the piercing foramen, easily squeezed and lead to low back pain.
