髋臼位相关参数在髋臼前柱前壁骨折术中定位的临床意义

摘要

目的 探讨髋关节的相关参数外展角、前倾角、顶弧角在髋臼前柱前壁骨折术中定位的意义.方法 测量男女成人骨盆标本各109髋的髋臼外展角、前倾角、顶弧角及髋臼前柱前壁治疗安全角度,并将数据进行统计学分析.结果 男性骨盆标本髋臼外展角实测值(43.5±2.9)°,前倾角实测值(13.7±5.2)°,顶弧角的内顶弧角(25.5±7.3)°、前顶弧角(37.8±7.2)°、后顶弧角(49.9±12.7)°;女性骨盆标本髋臼外展角实测值(44.1±3.2)°,前倾角实测值(14.3±4.9)°,顶弧角的内顶弧角(27.1±6.5)°、前顶弧角(36.3±9.2)°、后顶弧角(52.3±13.6)°.根据"2-7"分割线测量髋臼前柱前壁厚度.外展角、前倾角、顶弧角比较,差异有统计学意义(P<0.05).三者与髋臼前壁厚度差异无统计学意义(P>0.05).不同性别之间的髋臼外展角、前倾角、顶弧角差异无统计学意义(P>0.05).结论 髋臼外展角、前倾角、顶弧角的测量在髋臼前柱前壁骨折的术中定位能够取得满意的治疗效果.%Objective To study the significance of the related parameters of the abduction angle ,anteversion angle and summit arc angle in the intraoperative localization of anterior column and anterior wall acetabular fractures .Methods The safety angle of abduction angle ,an-teversion angle,summit arc angle and anterior wall acetabular of 318 adult pelvic specimen(109 males and 109 females) were measured.The data was statistical analyzed.Results For the male pelvic specimen,the measured values of abduction angle of acetabulum was (43.5 ± 2.9)°, anteversion angle was (13.7 ±5.2)°,summit arc angle inside was(25.5 ±7.3)°,summit arc angle front was(37.8 ±7.2)°,sum-mit arc angle back(49.9 ±12.7)°.For female pelvic specimen,the measured values of abduction angles of acetabulum was (44.1 ±3.2)° and anteversion angle was (14.3 ±4.9)°,summit arc angle inside was(27.1 ±6.5)°,summit arc angle front was(36.3 ±9.2)°,summit arc angle back was(52.3 ±13.6)°.According to '2-7' sector method, the thickness of different point of anterior wall was measured .There were statistically significant differences in abduction angles ,anteversion angle and summit arc angle (P<0.05).And there was no statistically sig-nificant difference in the thickness of anterior column and anterior wall between the above three one angles (P>0.05),there was no signifi-cant difference in the acetabular abduction angle ,anteversion angle and summit arc angle between males and females .Conclusion The intra-operative localization of acetabulum abducted angle ,anteversion angle and summit arc angle in the acetabulum anterior column and anterior wall fractures can achieve satisfactory therapeutic effect .
