国人腰椎管外骨纤维管与脊神经的关系 Ⅰ.腰神经后内侧支骨纤维管的观察及其临床意义

THE RELATION BETWEEN THE OSTEO-FIBROUS CANAL OUTSIDE OF THE LUMBAR SPINAL CANAL AND THE SPINAL NERVE PASSING THROUGH IT. Ⅰ.THE MORPHOLOGY OF THE OSTEO-FIBROUS CANAL OF THE MEDIAL DIVISION OF POSTERIOR RAMUS OF THE LUMBAR NERVE WITH SPECIAL REFER

本文观察了80侧男女尸体的384个腰神经后内侧支骨纤维管的位置,组成和上关节突副突韧带的形成。对骨纤维管外口的长径、宽径进行了测量。将管外口分为:近圆形35.14%(151)侧、近椭圆形32.29%(124)侧、裂隙形28.39%(109)侧等三个类型。腰神经后内侧支骨纤维管由乳突、副突、乳突副突间沟和上关节突副突韧带组成。依其前、后壁的结构分为:骨腱膜韧带型29.43%(113侧),骨骨膜韧带型66.4%(255侧)、骨型4.17%(16侧)。测量了上关节突副突韧带的长度、宽度、厚度,其中腰韧带的长度,在男女有显著性差别。观测骶骨上关节突骶骨翼间沟的长度和宽度。并认为腰神经后内侧支骨纤维管的后壁韧带称作上关节突副突韧带为宜。

1.40 cadavers were dissected in order to observe the position and formation of the osteo-fibrous canal(384 canals)of the medial division of posterior ramus of lumbar nerves together with the occurrence of the articulo-accessory(process)ligament.2.The form of the external opening of the osteo-fibrous canal may be classified into three groups;nearly circular 35.1%(151);approximately ellipsoid 32.3%(124);crack detector 28.4%(109).3.The osteo-fibrous canal consists of four walls,bounded by mammillary process,accessory process,bony wall and superior articular process ligament respectively.According to the constitution of the anterior and posterior walls of the canal,it may be divided into three categories;osteo-aponeuroticoligamentous type 29.4%(113);osteo-membranous type 66.4%(255)and bony type 4.2%(16).4.The length and width of the superior articular process ligament were measured.The sexual difference of the lengths of Llumbar is significant.5.The sulcus between the superior articular process and the alar portion of the sacrum was observed and measured.6.The ligament on the posterior wall of the canal is nominated as the ligament of the superior articular process.7.Based on the anatomical structures thus studied,some clinical significances were discussed.
