摘要
目的:研究三种腰椎椎弓根定位方法与椎弓根的解剖关系,为腰椎椎弓根选择定位方法提供客观依据.方法:选取正常成人L1～L5节段干燥骨标本50具,测量横突定位法、人字嵴顶点定位法、棘突定位法与椎弓根中轴线及上下缘内外缘的解剖关系,比较三种定位方法的优缺点.结果:三种方法与椎弓根的解剖关系存在差异;在垂直向人字嵴顶点定位法与椎弓根关系最近,而水平向关系最远;L1～L4横突法及棘突法二者与椎弓根的解剖关系差别不大(P＞0.05);综合比较解剖关系及临床应用各方面,建议L1～L4椎弓根定位优先选择次序为人字嵴法-棘突法-横突法,L5椎弓根定位优先选择次序为横突法-人字嵴法-棘突法.结论:三种定位方法各有特点,人字嵴法、棘突法比横突法更适合临床应用.
Objective：To investigate the anatomic relationship between three transpedicular localization meth- ods and pedicle of lumbar vertebrae and offer objective basis for selection of which option.Method：Fifty dry normal adult skeletons（L1-L5） were obtained,the distance from transverse process anchoring point,the “∧” shape crest anchoring point and spinous process pedicle anchoring point to superior,inferior,medial and lateral edge and to axis of vertebral pedical were measured,comparement between the three options were analysed. Result：The anatomic relationship between anchoring point to vertebral pedicle was different in three methods, the vertical distance from “∧” shape crest anchoring point to vertebrae pedicle was the nearest in three methods,but the horizontal distance was the rarest in three methods.There was no statistical significant differ- ence between transverse process method and spinous process method at L1-L4（P〉O.O5）.Combined with clinical application,we suggest the “∧”shape crest method（SCM） over spinous process method（SPM） and SPM over transverse process method （TPM） in terms of pedical localization at L1-L4,at L5 the order was TPM,SCM and SPM.Conclusion：Three localization methods have different characteristics separately,but “∧” shape crest method and spinous process method is superior to transverse process method in clinical application.
