  acetabular anteversion
This global assessment and, in particular, the presence and value of true acetabular anteversion represent the basic study before indicating an innominate osteotomy.
      
The caudal, central, and cranial acetabular anteversion diminished with the ventral tilt of the pelvis.
      
Attracted by the very changeable morphology of the acetabular cover, we studied the caudal, central, and cranial acetabular anteversion of 12?pelvises in four positions of dorsal-ventral inclination.
      
Variations of acetabular anteversion measured at the level of the diameter of the acetabulum according to the tilt of the pelvis are known.

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...

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。

Objective To explore the changes of the acetabular anteversion in developmental dysplasia of the hip. Methods Acetabular anteversion was measured by computed tomography(CT) in 18 patients with unilateral hip dysplasia. The acetabular anteversion was analyzed in the dysplasia hips and the normal side. All patients were operated on to correct hip dysplasia. CT were used in 6 patients in 6 months after the operation and the changes of the acetabular anteversion were analyzed. Results No statistically significant difference was found in acetabular anteversion between the dysplasia and the normal side. The operation to correct hip dysplasia produced an abnormality in acetabular anteversion. Conclusion Acetabular anteversion in the dysplasia hips resembled the normal side. Acetabular anteversion can be changed in the operation.

Objective:To analyse the causes of postoperative dislocation after total hip replacement (THR) owing to acetabular or proximal femoral deformities and to find the preventive measures.Methods:Of the 172 cases treated by THR postoperative dislocation after THR was found in 5 cases(2.9%).Posterior dislocation occurred in 4 cases and anterior dislocation occurred in 1 case.The postoperative dislocation occurred from immediately after operation when shifting the patient to 20 days after opration.Four cases had congenital dysplasia of acetabulum and too small anteversion angle,which was not adjusted during the operation and the other one had proximal femoral deformity and discongruency between prosthetic head and acetabulum.Results:Closed reduction was performed in two cases,followed by six week's traction or hip spica cast.2 cases were reduced operatively by adjusting the anteversion angle,and one by adjusting the prosthetic shaft.No redislocation was observed during the follow-up.Conclusion:To avoid the dislocation after THR,preoperative computer tomography plain scan can be used to judge the acetabular anteversion and the coverage on femoral head.Custom-made prosthesis should be provided before operation.The containment of socket may be increased by enlarging and deepening the acetabulum intraoperatively.The congruency between prosthetic head and acetabulum can be enhanced by adjusting the neck-shaft angle.The intraoperative trial stability of hip prosthesis will decrease the risk of dislocation.

目的 :分析髋臼及股骨上端畸形致人工髋关节置换 (THR)术后脱位的原因 ,探讨防治对策。方法 :本组行全髋置换术 172例后发生脱位 5例 (2 .9% ) ,其中后脱位 4例 ,前脱位 1例。发生时间最早在术毕搬动时 ,最迟在术后第 2 0天。脱位原因分析 ,4例存在先天性髋臼发育不良 ,前倾角过小 ,术中未能调整 ;1例为股骨上端畸形 ,假体头臼对合不良。结果 :复位后牵引 6周 1例、髋人字石膏固定 6周 1例 ,手术调整前倾角 2例、调整股骨假体柄 1例 ,均未发生再脱位。结论 :为避免发生脱位 ,术前CT平扫了解髋臼前倾角和股骨头包容程度 ,做好特殊假体准备 ;术中加大加深髋臼以增加臼杯的包容度 ,并调整股骨头、颈角度来配合对应关系。术中人工髋试活动稳定性良好是减少术后脱位保证。
