摘　　要：目的探讨不同体位对EBRA法测量人工髋关节假体磨损的影响。方法回顾性分析30例在本院接受人工全髋关节置换术的患者的临床资料。所有患者当天连续拍摄平卧位2张、站立位2张骨盆片。在EBRA法设定可比性为3 mm的条件下,分别测量同一体位间、不同体位间的假体磨损率,比较平卧位间、站立位间、平卧位与站立位间可以进行EBRA测量次数的差异,比较平卧位间、站立位间、平卧位与站立位间的EBRA测量假体磨损的差异。结果在平卧位下拍摄骨盆片,有23次(77. 0%)允许进行测量髋臼和股骨头假体位移。在站立位下拍摄骨盆片,有25次(83. 0%)允许进一步测量。比较不同体位下拍摄骨盆平片,有43次(35. 0%)允许进一步测量。上述差异有统计学意义(P <0. 05)。比较同一体位或不同体位下拍摄骨盆片的髋臼假体和股骨头假体相对位移的变化,平卧位间、站立位间和不同体位间的骨盆片差异无统计学意义(P> 0. 05)。结论对比不同体位下拍摄的骨盆片,满足EBRA法测量要求的骨盆片数量减少;对比满足测量要求的骨盆片,体位变化对EBRA法测量假体间位移变化无显著影响。Objective To explore the influence of different positions on prosthesis abrasion measured by EBRA method.Methods Clinical materials of 30 patients with total hip replacement were analyzed retrospectively.All the patients took 2 pelvic films in supine position and 2 pelvic films in standing position on the day of examination.Under the condition of 3 mm comparability set by EBRA method,the rates of prostheses abrasion in the same position and different positions were measured respectively.The differences of the numbers of EBRA measurements between supine position and supine position,standing position and standing position,supine position and standing position were compared,and the differences of prostheses abrasion measured by EBRA between supine position and supine position,standing position and standing position,supine position and standing position were compared as well.Results In the pelvic radiographs taken in supine position,23 times(77.0%)were allowed to measure the displacement of acetabulum and femoral head prosthesis.In the pelvic radiographs taken in standing position,25 times(83.0%)allowed further measurements.In the comparison of pelvic films taken in different positions,43 times(35.0%)allowed further measurements,and there were significant differences(P<0.05).In the comparison of the relative displacement of acetabular and femoral head prostheses taken in the same position or different positions,there were no significant differences between supine position and supine position,standing position and standing position,and different positions(P>0.05).Conclusion In the comparison of the pelvic films taken in different positions,the number of pelvic films meeting the requirements of EBRA method was reduced.For the pelvic films meeting the requirements of measurement,the change of position had no significant effect on the displacement of prosthesis measured by EBRA method.
