【摘要】 目的观察前交叉韧带(ACL)胫骨附着处的解剖学形态,并对学术界存在的一些相关问题进行探讨。方法测量中国人干燥骨骼标本ACL胫骨附着处的大小、形态、位置。结果最大横径(9.38±1.67)mm;最大纵径(15.93±2.52)mm;附着区前缘距胫骨平台前缘的距离(7.85±1.52)mm;胫骨平台附着区长轴与胫骨平台平面正中矢状轴夹角(21.54±4.61)°;ACL的胫骨附着区形态主要以前宽后窄的倒三角形偏心形态为主(57.4%)。结论ACL胫骨附着处的特殊解剖位置有利于ACL在剧烈运动中具备较强的抗撕脱能力,另一方面亦导致了一旦ACL撕裂,往往会增加合并半月板损伤的发生率;A-CL纤维在胫骨附着处的不规则偏心分布形态为膝关节镜下ACL重建寻找“等长点”带来困难。更多还原

【Abstract】 Objective To observe ACL(anterior cruciate ligament)adherent area in t ibial eminence in a morphological and anatomical way and explore some relative p roblems. Methods Measure the dimensions,positions and profile of ACL adherent a rea in tibial eminence of 101 dry Chinese skeleton-specimens. Results Width of a dherent area was (9.38±1.67)mm,length (15.93±2.52)mm,the distance from front m argin of ACL adherent area in tibial eminence to front margin of tibial eminence was(7.85±1.52)mm,the angle from axis of ACL adherent area to median sagittal a xis was(21.54±4.61)°,the majority(57.4%)in the profile of ACL adherent area in tibial eminence was likely a inverted triangle. Conclusion The stability of AC L against exterior lacerating forces under varied extreme motions is strengthene d by the anatomical position of ACL adherent area in tibial eminence meanwhile A CL being lacerated may cause the increase rate of meniscus injures in knee joint . The irregular distribution of fibre within ACL adherent area in tibial eminenc e bring difficulties in locating the entrance of tibial channel in reconstructio n of ACL by arthroscopic assisted "isometric point".更多还原
