【Abstract】 [ObjectivelObserve the morphous,position of lumbar zygapophyseal joints and govern nerves and their relations with surrounding tissues,and provide morphological evidence and anatomic data.[Method]1.To choose 15（30 sides） lumbar spinal columns of formalin-treated adult corpses,step by step anatomise zygapophysial joints,then described and measured its mophous,position, the connection with surrounding tissues and position,Courser of govern nerves.2.Observe the type of 50 lumbar zygapophysial joints and desiccated adult spinalis skeleton specimens.3.To collect 300 orthophoric radiographs of adult lumbar,and observe the connection between the top line of iliac crest and vertebral segment.[Result]1.zygapophysial joint is in the two sides of midline of the processus spinosus,its artic amplitude is between the superior articular process of one vertebra and the inferior articular process of the vertebra directly above it.The distance between superior border of lumbar’ zygapophysial joint and posterior median line are as follows（mm）:13.27±0.92、15.01±1.27、17.03±1.86、19.64±2.48、23.41±2.65,to the body surface are as follows（mm）:32.39±1.93、35.35±1.97、39.29±1.78、43.68±2.98、46.83±1.56;between the inferior border and posterior median line are as follows（mm）:12.94±0.90、14.40±1.88、15.91±2.24、18.09±3.04、22.77±2.86,to the body surface are as follows（mm）:32.63±1.75、36.09±1.77、39.92±1.57、44.73±1.52、46.70±1.51.2.Between superior articular process and transverse process,there is lumbar nerve of posterior media branch into the bone groove,through the osteo-fibrous canal under the rear running inwards.The distance between osteo-fibrous canal and posterior median line are as follows（mm）:20.91±1.09、22.51±1.48、24.83±1.51、27.29±1.25、29.28±0.93;to the body surface are as follows（mm）:29.49±1.57、33.48±1.76、37.52±1.26、40.42±1.57、42.24±1.66.3.The lateral branch of lumbar posterior divisions pass obliquely outward behind the Intervertebral foramina cross with the backside of transverse process.The distance between transverse process and posterior median line are as follows（mm）:22.6±1.26、24.35±1.19、26.88±1.50、30.17±1.72、32.26±1.51;to the body surface are as follows（mm）: 31.55±1.78、35.67±1.77、38.65±1.38、42.51±1.39、45.97±1.37.4.There is 31%planar type and 69%concave type of L₁-S₁ zygapophyseal joints,few down（2%）and dual concave type（1%）. 5.Between the top line of iliac crest and spinous process midline,male is in L4 spinous process,but female is the L4-5 interstice.[Conclusion]1.The puncture of lumbar zygapophyseal joints should,perpendicular needle insertion at the outside of corresponding spinous process interstice midpoint（12.94±0.90～22.77±2.86）mm,the depth of needle insertion is（32.63±1.75～46.70±1.51）mm.2.The puncture of medial branch of lumbar posterior divisions should perpendicular needle insertion at the outside of corresponding spinous process interstice midpoint （20.91±1.09～29.28±0.93）mm,the depth of needle insertion is（29.49±1.57～42.24±1.66） mm.3.The puncture of lateral branch of lumbar posterior divisions should perpendicular needle insertion at the outside of corresponding spinous process inferior border（22.62±1.26～32.26±1.51）mm,the depth of needle insertion is（31.55±1.78～45.97±1.37）mm.更多还原
