摘要：

背景：人工全膝关节置换手术中常用到第2跖骨干轴线作为参照，其通过踝关节的位置还不明确。
目的：确立一种新的激光瞄准定位可重复的标准体位下下肢X射线照片方法，分析正常中国南方汉族青年人第2跖骨干轴线与踝关节中心的关系。
方法：志愿者分为3组：①采用新方法由同一操作者标记皮肤，指导拍片体位。②采用新方法由不同操作者标记皮肤，指导拍片体位。③用常规方法不标记皮肤拍片做对照。每位均照片2次。
结果与结论：同一操作者与不同操作者操作差异无显著性意义(P=0.729)，均与常规方法差异有显著性意义(P=0.017)，前两组2次照片差值绝对值比对照组小，重复性比对照组高。使用新照片方法，在踝关节线水平第2跖骨干轴线到踝关节外缘的距离和到踝关节内缘的距离比值为1.06±0.882。在临床上可以认为第2跖骨干轴线经过踝关节中点。

Abstract:

BACKGROUND: During total knee arthroplasty surgery, second metatarsal shaft axis is consider as a reference, but its position through the ankle joint is unclear.
OBJECTIVE: To establish a new laser aiming reproducible standard full-length lower limb radiography, to use the method to evaluate the relationship between the second metatarsal shaft axis and the center of the ankle in healthy southern Han Chinese adults.
METHODS: All subjects were divided into 3 groups: ① The new method was adopted to mark skin by same tester who guided the filming position of patients. ② The new method was adopted to mark skin by different testers. ③ Routine radiography was used as control without mark. Twice radiography was done for each subject.
RESULTS AND CONCLUSION: There was no difference of the testers in the group 1 and group 2 (P=0.729), but had difference in the group 1 and group 3 (P=0.017). Absolute value in two radiography of the groups 1 and 2 was lower than that of the group 3,  repeatability in the groups 1 and 2 was higher than the group 3. Using the new method, the ratio of the distance from the second metatarsal shaft axis to the medial and lateral ends of the transverse axis of the ankle was 1.06±0.882. The view that the second metatarsal shaft axis passes the center of the ankle is acceptable clinically.
