摘　　要：背景:在人工全髋关节置换中,髋臼假体放置角度是否合适对手术临床疗效有着重要意义。目的:研究人工全髋关节置换后患者不同体位髋臼假体外展角及前倾角变化及其相关影响因素。方法:选择35例全髋关节置换后患者,其中男21例,女14例,年龄51-75岁,同一患者进行不同体位的X射线检查,分别为站立位骨盆前后位、站立位骨盆侧位片及卧位骨盆前后位X射线检查,测量髋臼假体外展角、前倾角等相关角度。结果与结论:1患者站立位的髋臼假体外展角、前倾角高于卧位(48.47°,45.89°;12.44°,6.17°,P<0.05);2前倾角改变主要与患者骨盆入射角、骨盆倾斜角相关;外展角的改变主要与患者骨盆歪斜角相关;3将髋臼假体外展角(40±10)°、前倾角(15±10)°的角度范围定义为安全区间;4结果表明:全髋关节置换后,站立位与卧位骨盆前后位摄片髋臼假体前倾角及外展角都有一定程度的改变,髋臼角度大小与患者骨盆歪斜角、骨盆入射角、骨盆倾斜角有关。BACKGROUND：During total hip arthroplasty,placement angle of acetabular prosthesis is significant for clinical curative effects.OBJECTIVE：To investigate the abduction angle and anteversion angle of acetabular prosthesis at different positions during total hip arthroplasty and related influential factors.METHODS：Thirty-five patients undergoing total hip arthroplasty were included in this study,containing 21 males and 14 females,at the age of 51-75 years old.The same patient at different positions underwent X-ray examination,including standing anteroposterior pelvis radiographic imaging,standing lateral radiographic imaging and supine anteroposterior pelvis radiographic imaging.Abduction angle and anteversion angle of acetabular prosthesis were measured.RESULTS AND CONCLUSION：（1） Abduction angle and anteversion angle at standing position were bigger than that at supine position（48.47°,45.89°;12.44°,6.17°;P〈 0.05）.（2） The change in anteversion angle was associated with pelvic incidence angle and pelvic tilt angle.The change in abduction angle was associated with pelvic obliquity.（3） The range of abduction angle（40±10）° and anteversion angle（15±10）° of acetabular prosthesis was identified as security zone.（4） Results suggested that there were changes in acetabular abduction angle and anteversion angle between supine anteroposterior pelvis radiographic imaging and standing anteroposterior pelvis radiographic imaging after total hip arthroplasty.Acetabular angle was associated with pelvic obliquity,pelvic incidence and pelvic tilt.
