腰脊神经在椎管内受压(包括:椎管、神经根管、侧隐窝以及椎间孔)。是腰腿痛的重要原因之一,因而已对腰椎管的解剖作了比较详细深入的研究(附图)。国内文献报道很多,至于椎管外的解剖结构是否潜在有腰神经受压的因素,李怀先等(解剖学报1986;16:244)报道了在 L_(1-5)椎间孔的后外方,存在包绕神经后支的骨纤维管,由上关节突外侧缘 Lumbar spinal nerve compression in the spinal canal (including: spinal canal, nerve root canal, lateral recess and intervertebral foramen). Is one of the important reasons for low back pain, which has made a detailed and in-depth study of the anatomy of the lumbar canal (with photos). There are many reports in the domestic literature. As for whether the anatomical structure outside the spinal canal is potentially a cause of lumbar nerve compression, Li et al. (Anatomy 1986; 16: 244) reported that after the L_ (1-5) posterior foramen, There is a fibrous tube surrounding the posterior branch of the nerve, the lateral margin of the superior articular process
