摘要
目的研究X线下前交叉韧带(anterior cruciate ligament,ACL)起止点印迹在股骨髁及胫骨平台上的定位,为术中重建ACL制备骨隧道时提供参考依据。方法采集12例正常国人膝关节标本,制作标本后分别在股骨髁及胫骨平台将ACL起止点边缘用金属丝标记,标记后摄标准的正侧位膝关节标本x线片,使用X-Caliper测量仪在CR片上精确测量ACL股骨髁和胫骨平台止点的几何中心与CR片骨性标记之间的距离。结果ACL股骨侧止点中心在股骨干力学轴与其平行线之间(65．3±1．1)%处,在Blumensaat线及其平行线之间(78．1±1．0)%处。胫骨侧止点中心在正位片上位于胫骨平台(47．1±2．6)%处,在侧位片位于(43．9±1．7)%处。结论股骨干力学轴和Blumensaat线及与其平行的股骨髁切线结合更方便定位ACL股骨侧标记；X线下胫骨平台定位更为准确。
Objective To study attachment of anterior cruciate ligament （ACL） at femoral condyle and tibial plateau on CR radiographs so as to provide reference for localization of insertion site in ACL reconstruction. Methods Twelve normal Chinese human knee specimens were fully inspected for its integrity and marked at both femur and tibia with metal wires. Standard radiographs of anteroposterior view and lateral view of the specimen were used for measuring the attachment site of ACL to femur and tibial plateau by X-Caliper in order to locate its insertion site. Results The center of ACL footprint was found at （65.3 ± 1.1 ） % and （ 78.1 ± 1.0 ） % respectively in between mechanical axial of femur and Blumensaat line and their paralleled condylar line. The center of tibial ACL attachment spans was approximately at （47.1 ± 2.6） % of the sagittal depth and （43.9 ± 1.7 ） % of the coronal depth of tibial plateau. Conclusion Mechanical axis of femoral stem and Blumensaat line combined with tangent line of the condyles are good for locating femoral insertion site of ACL on a perfect lateral projection radiograph, Attachment is more precise on tibial plateau under X-ray.
