摘　　要：目的通过对比EOS成像系统(EOS imaging system),来评估全幅数字X线摄影(the full view digital radiography,DR)图像所测量下肢力线的准确性。方法本研究为前瞻性研究。对同一个膝关节骨关节炎患者在同一天分别使用全幅DR和EOS成像系统进行下肢全长检查并测量下肢力线。结果共纳入27例,其中男6例,女21例。年龄48~80岁,平均(63.67±7.68)岁。所有研究对象分左、右下肢分别测量,共54例。下肢力线的测量在全幅DR和EOS成像系统两种检查方法,差异均无统计学意义(P>0.05),其中髋膝踝角(hip-knee-ankle angle,HKA)的P值为0.331,股骨远端外侧角(lateral distal femoral angle,LDFA)的P值为0.140,胫骨近端内侧角(medial proximal tibial angle,MPTA)的P值为0.359,股骨胫骨关节线夹角(joint line convergence angle,JLCA)的P值为0.974。结论全幅DR虽然存在边缘放大效应,但对于下肢力线测量的影响较小。Objective To evaluate the accuracy of lower limb force lines measured in full view DR images by comparing EOS imaging systems.Methods This study was a prospective study.A full view DR and EOS imaging systems were used to perform a full-length examination of the lower limb and measure the lower limb force line for the same patient with knee osteoarthritis.Results A total of 27 patients was included(6 males and 21 females).The age ranged from 48 to 80 years old,with an average of(63.67±7.68)years.All research subjects were measured separately for the left and right lower limbs,with a total of 54 cases.There was no statistically signifcant difference in the measurement of lower limb force line between the full-range DR and EOS imaging systems(P>0.05).The P-value of hip-knee-ankle was 0.331,the P-value of lateral distal femoral angle was 0.140,the P-value of medial proximal tibial angle was 0.359 and the P-value of joint line convergence angle was 0.974.Conclusions Although full view DR has edge amplifcation effect,its impact on lower limb force line measurement is relatively small.
