摘要
作者通过对１１２个正常髋臼外展角和前倾角随骨盆前倾度改变而变化的动态测量研究，制作出髋臼两角与骨盆倾度之间的相关变化曲线。根据结果和曲线分析而知：（１）正常成人站立和行走时的髋臼外展角约为４０°～４７°，前倾角为４°～２０°，男性与女性之间无显著性差异（Ｐ＞０．０５）；（２）髋臼前倾角的存在使外展角在屈髋活动时减小比较缓慢，保证了髋臼对股骨头较好的覆盖；（３）骨盆倾度的改变对髋臼前倾角的大小影响较大，骨盆倾度每增大１０°，前倾角即减小６°。该结果为临床全髋置换术前判断髋臼位相，术中正确放置人工臼杯，术后指导髋关节功能锻炼，提供了可靠的解剖依据。
AbstractTwo anatomical curves were made through dy-namic measurement of the angles of acetabular abduc-tion and anteversion with the change of inclination ofthe pelvis. On the basis of the analysis of the curves,the following are known:(1)the normal range of ac-etabular abduction of standing adult is 40°～ 47°,theanteversiOn is 4°～20°,and there is no significance dif-ference between male and female(P> 0. 05);(2)theexistence of the anteversion makes the angle of the ab-duction reduced slowly with the increase of hip flexionand maitains better coverage of the acetabulum for thefemoral head;(3) the change of inclination of thepelvis influcences the level of acetabular anteversion,as inclination of the pelvis increases 10°, the antever-sion reduces 6°.The above results provide reliableanatomical basis for total hip replacement.
