There were 36 males and 40 females,with the average age of 47.7 years.36 patients presented with sciatica and perineal numbness,11 patients had painless mass and the other 20 were identified due to other causes.Among 67 benign neurogenic tumors,54 were originated from S1-S3 nerves,3 from S4-S5 nerves and 11 from the presacral space without caudal involvement.Giant cell tumor was found in 60 patients,which included 24 males and 36 females,with an average age of 32 years.Upper sacrum（S1-S2） was involved firstly.There were 56 patients（average,37.7 years） diagnosed as other primary benign bone tumors,which included 24 cases of teratomas,epidermoid cyst or dermoid cyst.Other malignant tumors,including chondrosarcoma （17）,Ewing′s sarcoma/PNET（14）,multiple myeloma（12）,lymphoma（6） and osteosarcoma（6） were found in 64 patients.

其中脊索瘤95例，男62例，女33例，平均年龄55.7岁，骶尾区疼痛是主要症状（82例），半数以上患者伴有坐骨神经痛，肿瘤多先累及低位骶骨（S3~S5）；神经源性肿瘤76例，男36例，女40例，平均年龄47.7岁，神经纤维瘤43例，神经鞘瘤24例，恶性神经鞘瘤9例，主诉多为坐骨神经痛、会阴部麻木（36例）和无痛性包块（11例），20例患者为查体或其他原因检查时发现，67例骶骨良性神经源性肿瘤起源于S3以上神经者54例，起源于S3以下神经者3例，发生于骶前未累及骶管者10例；骨巨细胞瘤60例，男24例，女36例，平均年龄32岁，腰骶尾部不适（37例）、坐骨神经痛（21例）是主要的临床表现，肿瘤多先累及上位骶骨（S1~S2）；骶骨其他原发良性肿瘤及瘤样病变56例，包括畸胎瘤、皮样囊肿、表皮样囊肿共24例；其他原发恶性肿瘤64例，包括软骨肉瘤17例，尤文肉瘤14例，多发性骨髓瘤12例，成骨肉瘤6例等。

Methods Employing cholera toxin B-subunit combined horseradish peroxidase retrograde tracing technique and cholera toxin B-subunit combined colloid goldretrograde tracing with calcitonin gene-related peptideimmunohistochemical double-labeled staining technique,the innervation of musculus sacrococcygeus ventralis medialisin rats was studied.

大鼠骶尾腹内侧肌又称荐尾腹侧中肌(musculus sacrococcygeus ventralis medialis)或屈尾短肌，是位于盆腔后壁、骶椎前方的一对梭形肌肉，属尾肌群，因其功能似乎仅为屈尾，故至今尚未引起人们的注意，而与该肌位置关系较密切的会阴肌因在某些运动神经元疾患时仍可保持其正常生理功能而一直受到神经工作者的关注，尤其是近年来有诸多文献报道了会阴肌的神经支配、相关神经元的细胞构筑、神经递质和神经调质的分布以及纤维联系特点［1～10］，藉以探讨运动神经元疾病的神经病理学。

Results We found firstly that the SCVM was innervated by both somatic motor neurons of ventral group and Onuf's nucleus in ventral horn of the spinal cord,which is similar as perineal muscles,that means double innervation.
