髋臼的

In particular, the acetabular component anteversion can be difficult to determine on plain radiographs and as this is frequently an issue resulting in instability, accurate assessment is required.7

特别强调的是，髋臼假体的前倾在平片上难于评估，因此这往往是导致不稳定的潜在因素，精确的测量其角度是有必要的。

1 Age use jiaopidou, 1-3 age use plasticity aluminium plank The patient is older who has heavy pathological changes use the three unite operation, The Chinese medicine is used by interior and external , push to take and to do exercises , observe the structural variety of the hip by measuring the femoral neck angle of anteversion and the index acetabulum, CE angle, the femoral head overlay rate.

年龄大、病变重的患者可行三联术，并结合中药内服、外敷、推拿练功治疗；0～3岁通过功能评定，而3岁以上才采用测量治疗前后股骨颈前倾角的变化、髋臼指数的变化、 CE角的变化、股骨头覆盖率的变化及功能评定，从而观察髋关节功能及结构的变化。

Conclusion］1? It showes a higher stress dodge in the calcar femorale after using various kinds of prosthesis implantation? After using CFR/PSF of lower elastic modulus as handle, the stress dodge rate is lower in femur, but the interface stress is higher, and this is the main factor and reason for the prosthesis loosening? 2? The stress force rule meets the design principle that the stress force decreases gradually in the bone interface from proximal to distal? The stress value in different combination of same prosthesis handle has no significant difference, that showes mechanical factor is not the main standard for selecting prosthesis combination?

［结论］ 1、各种假体植入后均在股骨距处形成较高的应力遮挡，而用弹性模量较低的CFR/PSF作为柄，其股骨相应区域的应力遮挡率较低，但股骨相应界面应力较大，而界面应力过大是产生假体微动主要因素。2、股骨界面从近端至远端呈逐渐增高趋势的应力规律符合该假体的设计原理；相同假体柄的不同组合其股骨和髋臼相应界面应力值无明显差别，实验表明力学因素并不是选择假体组合的主要标准。

The AP view of the hip at 3 days, 3 months, 1 year and yearly after the operation were obtained, cup migration according to the teardrop and radiolucent line were evaluated, at the same time the Harris hip score were also evaluated.

拍摄术后3 d、3个月、1年及每年随访时的双髋正位片，以泪滴为参照，观察聚乙烯臼杯位置的变化及骨水泥层透亮线的变化，并进行Harris髋关节评分比较。

Topography map of the hip bone displays the depth of all parts of the hip bone and the projection of important blood vessel and nerve onto the hip bone imaginarily and directly. Deep understanding of topography map of the hip bone may prevent vital blood vessel and nerve from accidental injury during the operation of internal fixation of pelvic fracture and acetabular fracture.

提示髋骨的地形图形象、直观地表达了髋骨各个部位的厚度、重要血管和神经在髋骨表面的投影，深入地了解髋骨的地形图能够在骨盆骨折和髋臼骨折内固定中防止重要血管和神经的意外损伤发生。

These were ealuated forCobb angle, end ertebrae selection, Ferguson angle, apex of the cure, C7 balance, pelic obliquity, Risser sign,status of the triradiate cartilage, kyphosis Cobb angle, endplate selection for kyphosis, and kyphotic index.

分别从Cobb角，终椎的选择，Ferguson角，顶椎的选择， C7平衡，骨盆倾斜， Risser征，髋臼&Y&软骨的情况，脊柱后凸Cobb角，脊柱后凸的终板选择，脊柱后凸指数进行测量。

Methods From March 1994 to December 2002, on the basis of the ordinary operative method, Pemberton method was improved for 48 cases of DDH 49 articulatio coxae which had superficial and small acetabula but big heads of femur. Osteotomy points were moved higher to enlarge area of bone flap turned over. A piece of full thickness ilium including periosteum was removed as a free bony graft. Capsula articularis growing thicker was made into 2 layers, of which the inner layer was used to tighten articularis and the outer layer was used to stabilize bone flap.

1994年3月～2002年12月，对DDH髋臼浅而小、股骨头大的48例49个髋关节，在通常术式的基础上，对Pemberton截骨术式进行改良，将截骨点上移，扩大翻转骨瓣面积；取髂骨全层骨板连带附着的骨膜植骨；增厚的关节囊制成两层，内层紧缩关节，外层稳定骨瓣。

Afterwards, one-foot standing position was simulated to conduct the loading and constraint of the model,the Mises and shear force distributing of the cup were analyzed,forecasting the mechanical risk of prosthetic failure.

模拟人体单足站立状态，而后对重建的人体骨盆模型进行力的加载与约束，分析髋臼内Mises 应力及剪切应力的分布情况，预测术后假体失效的力学危险性。
