目的探讨拍摄体位对发育性髋关节发育不良(developmental dysplasia of the hip,DDH)患者骨盆矢状面倾斜及髋关节发育X线参数的影响。方法2015年12月2016年10月收集接受伯尔尼髋关节周围截骨术的女性DDH患者78例(DDH组),年龄(28.41±...目的探讨拍摄体位对发育性髋关节发育不良(developmental dysplasia of the hip,DDH)患者骨盆矢状面倾斜及髋关节发育X线参数的影响。方法2015年12月2016年10月收集接受伯尔尼髋关节周围截骨术的女性DDH患者78例(DDH组),年龄(28.41±9.91)岁(范围18~49岁);共135髋,单侧21例、双侧57例。另招募26名(52髋)无脊柱及髋关节疾病的女性志愿者(对照组),年龄(23.54±5.58)岁(范围18~49岁)。两组均拍摄仰卧位和站立位骨盆前后位X线片。通过测量骶尾关节至耻骨联合的距离(pubic symphysis to sacrococcygeal distance,PSSC)评估骨盆矢状面倾斜程度,以外侧中央边缘角、臼顶倾斜角、Sharp角评估髋关节发育不良程度,以泪滴距评估股骨头与髋臼的水平位置关系。数据均由两名测量者分别测量2次,分析骨盆及髋关节参数与拍摄体位的相关性。结果对照组仰卧位和站立位PSSC分别为(53.73±16.22)mm、(36.45±14.21)mm,差值为(-17.28±8.07)mm,两组差异有统计学意义(t=-10.913,P=0.000);DDH组仰卧位和站立位PSSC分别为(56.76±13.54)mm、(48.62±15.44)mm,差值为(-8.13±13.02)mm,两组差异有统计学意义(t=-5.516,P=0.000);站立位时DDH组PSSC大于对照组,仰卧位时两组差异无统计学意义。单侧、双侧DDH患者两种体位PSSC的差异均无统计学意义(P>0.05)。对照组仰卧位和站立位外侧中央边缘角分别为30.33°±4.69°和29.70°±3.83°、臼顶倾斜角分别为4.05°±3.51°和4.36°±3.07°、Sharp角分别为40.53°±4.34°和41.79°±3.16°、泪滴距分别为(6.80±0.98)mm和(6.65±1.30)mm,差异均无统计学意义(P>0.05);DDH组仰卧位和站立位外侧中央边缘角分别为3.07°±12.07°和1.69°±12.11°、臼顶倾斜角分别为22.62°±9.31°和23.82°±9.45°、Sharp角分别为48.01°±4.68°和48.49°±4.74°、泪滴距分别为(10.51±3.51)mm和(10.93±4.23)mm,差异均有统计学意义(P<0.05)。结论从仰卧位到站立位骨盆矢状面以后倾为主要趋势,与正常女性比较DDH患者站立位时存在骨盆前倾,单双侧发病不是骨盆倾斜的影响因素。女性DDH患者从仰卧位到站立位,髋关节覆盖程度下降,股骨头出现水平外移,提示髋关节不稳定。展开更多
