目的 :观测腰神经后支骨纤维孔与腰神经后支卡压的关系。方法 :在 2 0具成人尸体标本上 ,观察腰神经后支与腰神经后支骨纤维孔的解剖学关系 ;测量该孔的纵横径及其体表定位。结果 :腰神经后支先穿过腰神经后支骨纤维孔后再分为内侧支和外侧支等 ;该孔L3 的纵、横径为 5 6± 0 9mm、 3 4± 0 5mm ,而L5的纵、横径为 3 5± 0 3mm、 2 1± 0 2mm ;L4、5横突间韧带的厚度分别为 1 5± 0 7mm、 2 0± 0 8mm ;体表定位在相对应的各腰椎平面距后正中线外侧约 30～ 40mm处。结论 :腰神经后支骨纤维孔的结构特点是造成腰神经后支卡压的形态学基础 ,并为临床治疗腰背痛提供解剖学依据
Objective: To observe the relationship between posterior lumbar nerve fiber branch and lumbar nerve posterior branch compression. Methods: Twenty adult cadaver specimens were examined for the anatomic relationship between the posterior lumbar nerve branches and the posterior bony branches of the lumbar nerves. The vertical and transverse diameters of the holes and their body surface were measured. Results: The posterior lumbar nerve branches first through the posterior lumbar nerve branches and then divided into medial branch and lateral branch. The longitudinal and transverse diameters of L3 of the lumbar nerve were 56 ± 0 9mm and 34 ± 0 5mm, while L5 The longitudinal and transverse diameters of the lumbar vertebrae were 35 ± 0 3mm and 21 ± 0 2mm respectively. The thickness of L4,5 transverse ligament was 15 ± 0 7mm and 20 ± 0 8mm respectively. Plane from the midline after about 30 ~ 40mm outside. CONCLUSION: The structural features of the posterior bony fibers in the lumbar nerve are the morphological basis for compression of the posterior lobe of the lumbar nerves, and provide an anatomical basis for clinical treatment of low back pain
