30 cases of "tripartite" or porcelain total hip prosthesis were followed-up and the causes of dislocation of the prosthesis were analysed. The incidence of postoperative dislocation in this group was 23.3%. The factors that caused dislocation were: trauma, over-flexion of the hip, retraction of the artificial acetabular cup with subsidence of the stem, the over abduction and anteversion of the cup, unfitness of the cup to the acetabula, flaccid femoral muscles, splitting of the greater trochanters,...

30 cases of "tripartite" or porcelain total hip prosthesis were followed-up and the causes of dislocation of the prosthesis were analysed. The incidence of postoperative dislocation in this group was 23.3%. The factors that caused dislocation were: trauma, over-flexion of the hip, retraction of the artificial acetabular cup with subsidence of the stem, the over abduction and anteversion of the cup, unfitness of the cup to the acetabula, flaccid femoral muscles, splitting of the greater trochanters, infections, etc. The incorrect positioning of the cup comprises the main factor in causing dislocation. The average abduction angle of the dislocated hips was 57.28° (45°—75°), the average anteversion angle was 16.86°(0—33°) and the average abduction angle of undislocated hips was 49.47° (23°—73°), the average anteversion angls was 12.5° (5°—30°). 2 of the 7 dislocated hips were reduced by skeletal traction, 2 were reoperated, 3 failed by traction, 1 was treated palliatively and 2 prostheses were removed. The related problems encountered were also discussed.

本文对施行“三合一”和全陶瓷人工全髋关节置换手术获得随访的30例患者进行小结,分析其术后并发人工髋关节后脱位的原因。本组7例并发后脱位,发生率为23.3%。脱位的原因有外伤、髋关节进度曲屈人工髋帽内陷和假体柄下沉、人工髋帽过度外展和和前倾、人工髋帽与髋臼不相称,股部肌张力松弛、大粗隆劈裂、感染等。髋帽位置的正确与否,是引起人工髋关节脱位的重要原因之一。

36 cases with 38 Hip joints underwent total hip replacement operation as per formed by the use of the first-generation cementing techniques. The immediate postoperative radiograph for the quality of cement-fixa tion revealed that grade B in 4 hips, grade C in 5 hips and grade D in 29 hips, and none belonged to grade A. At average 11-Year follow-up, clinical results were evaluated as excellent or good in 40%, fair in 32%, poor in 28%.X-ray film revealed that definite loosening of the femoral component was 32%,...

36 cases with 38 Hip joints underwent total hip replacement operation as per formed by the use of the first-generation cementing techniques. The immediate postoperative radiograph for the quality of cement-fixa tion revealed that grade B in 4 hips, grade C in 5 hips and grade D in 29 hips, and none belonged to grade A. At average 11-Year follow-up, clinical results were evaluated as excellent or good in 40%, fair in 32%, poor in 28%.X-ray film revealed that definite loosening of the femoral component was 32%, probable loosening was 40% and the possible loosening was 18%, and definite loosening of the acetabular cup component was 13%, the impending loosening was 18%. Of the poor 11 hips, revision operations were performed on 3 hips for the loosening of the femoral component, on 5 hips for the loosening of the cup component. The total revision rate is 21 %. This paper pointed out the disadvantage of the first-generation cementing techniques, prosthetic design, and the mechanism which would influence the long-term therapeutic results.

报道了第一代CTHR36例38髋的远期疗效。平均随访11年,功能优良15髋,尚可12髋,差11髋。股骨头假体:肯定松动12髋,很可能松动15髋和可能松动11髋。臼杯:肯定松动5髋,濒临松动7髋。总体修正手术率21%。表明第一代CTHR的远期疗效显著差于文献报道的第二代CTHR。作者认为这与前者的骨水泥固定质量和假体设计存在缺陷有关。

Objective:The design and initial stability of threaded acetabular prosthesis was studied in this paper. Method: The initial stability of threaded acetabular component was tested on the biomechanical test system. The threaded cup was fixed by direct rotation, the control group smooth acetabular cup was fixed with three cancellous screws. The forces moving prosthesis 100μm were tested at three direction of axial, clockwise and anti-clockwise. Results: The study shows that the threaded acetabular prosthesis...

Objective:The design and initial stability of threaded acetabular prosthesis was studied in this paper. Method: The initial stability of threaded acetabular component was tested on the biomechanical test system. The threaded cup was fixed by direct rotation, the control group smooth acetabular cup was fixed with three cancellous screws. The forces moving prosthesis 100μm were tested at three direction of axial, clockwise and anti-clockwise. Results: The study shows that the threaded acetabular prosthesis has excellent initial stability with significant difference in statistics and provide theoretical basis for this prosthesis applied in clinical practice.

目的:研究一种新型螺纹髋臼假体的设计及其初始稳定性。方法:螺纹髋臼假体通过直接旋入固定,对照组光面髋臼假体通过三枚松质骨螺钉固定。分别测定轴向、顺螺纹、反螺纹三个方向上的应力,以测定假体的稳定性。结果:螺纹髋臼假体的稳定性好,统计学分析有显著性意义。为该假体的临床应用提供了可靠的理论依据
