摘　　要：目的：为临床提供有关脊神经节（ｓｐｉｎａｌ ｇａｎｇｌｉｏｎ ，ＳＧ） 的形态学基础。方法：解剖观测了３８具（７６ 侧） 成人尸体标本的ＳＧ 形态。结果：①Ｃ１～尾部ＳＧ 长度和横径呈现同步变化的趋势，两值在Ｃ４ ～Ｔ２ ，Ｌ２～Ｓ４ 两次出现高峰区；②Ｓ１ 的ＳＧ 最大，尾ＳＧ 最小；③ＳＧ 长度与横径比值从大到小依次为骶部、腰部、尾部、颈部和胸部。结论：腰骶部ＳＧ 体积较大；对腰背痛患者，应充分考虑ＳＧ 受卡压的可能性；了解ＳＧ 的形态特征，有助于临床有关病症的诊治。To provide morphological data of SG (spinal ganglion) for clinic.Metods:The morphology of SG was studied on 38 adult cadaveric specimens (76 sides).Results:①From the C 1 nerve to Coccygeal nerve,the length and the width of SG change consistently.From C 4 to T 2 and from L 2 to S 4,there are two peaks respectively;②The SG on S 1 nerve is the largest one,and the coccygeal SG is the smallest one;③The ratio of the length to width of SG,from the maximum to minimum is sacral,lumbar,coccygeal,cervical and thoracic part.Conclusions:The size of lumbo sacral SG is large;and it is necessary to consider the possibility of SG being pressed in patients with low back pain.The knowledge of the morphology of SG is helpful to clinic.
