摘　　要：目的：为临床脊神经根性疾患的诊治提供解剖学基础。方法：对３５具（７０侧）成人尸体的全部脊神经前后根形态、位置、解剖汇合点和前后根的横径进行观测。结果：①脊神经后根有复根现象，双根的占２４．３％（双侧），三根占０．４％（双侧），而且有１．３２％的前根位于后根上方的变异；②前后根解剖汇合点８０％位于脊神经节的远端，２０％位于节的中部；③前后根横径之比在１１．５～２．５之间。结论：脊神经存有形态和位置上的变异，在临床手术治疗中应加以注意。bjective:To provide anatomic data for treatment of spinal nerve root diseases.Methods:All the spinal ventral roots and dorsal roots were observed on 35 adults cacaveric specimens (70 sides).Results:About 24.3% of the spinal dorsal root had two roots on both sides, and 0.4% of them had three roots.A few cases (1.32%) of the spinal ventral roots emerged higher than that of spinal dorsal roots from spinal cord.Eighty percent of ventral roots and dorsal roots joined together at the distal part of dorsal root ganglion,and the other 20% of them were at the middle part.Conclusions:During the operation attention should be paid on the morphologic and position variations of spinal nerve.
