在20具成人腰骶部脊柱标本上,观察了腰椎间关节及部分相关结构的神经分布.腰椎间关节主要由腰神经后内侧支支配,为单源多节段分布模式。后内侧支的行程为双“S”形,可使神经缓冲牵拉免受损伤,它经过狭窄弯曲的骨纤维管时可能易受嵌压导致下背痛.
The neurological distribution of lumbar intervertebral joints and some related structures were observed on 20 adult lumbosacral spine specimens.The lumbar intervertebral joint was dominated by the posterior medial branch of the lumbar nerve and was of single source and multi-segmental distribution pattern. The posterior medial branch has a double “S” -shaped stroke that cushions the nerve to pull it from injury. It may be susceptible to lower back pain when it passes through a narrow, curved canal.
