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。

While a prosthesis that is too large can cause problems, lucencies around the stem of the intentionally loose prosthesis and most changes in the capitellum do not appear to cause problems, at least in the short term.

假体过大可能导致一些问题，但至少在短期内，假体周围透亮影和多数肱骨小头的变化不会导致其他问题。

The femoral prosthesis of Corin rotaglide knee replacement system can reduce wearing of prosthesis and loosening. It fits well the young people.

提示Corin Rotaglide全膝关节置换减少了假体磨损和潜在的松动，尤其适合年轻活动量大的患者。

Methods Among 27 cases who perform cosmetic prosthesis for anterior tooth after crown lengthening, there are 16 cases with post crown,11 cases with comprehensive prosthesis.

对27例行牙冠延长术的患者进行常规的前牙美容修复，其中16例采用单纯桩冠修复，11例采用综合法进行美容修复。

Methods Pre revision X－ ray films of 39 aseptically loosened hip prosthesis were observed. The incidence of liner osteolysis and expansile osteolysis around components in different regions was statistically determined according to different kinds of prosthesis and the width or area of osteolysis.

方法观察因无菌性松动行翻修术的39个国产人工髋关节的术前X线片，按关节类型分组统计假体周围不同区域衬性和膨胀性骨溶解的发生率，并测算溶骨带宽度或溶骨面积。

"Explantation of a prosthesis is not feasible in situations such as a severely ill patient who is not a good candidate for anesthesia and surgery," senior author Dr. Raymund Razonable told Reuters,"or a patient who has poor/weak bone reserve so that reimplantation of a functional prosthesis at a later time is not feasible."

资深的Raymund Razonable博士告诉路透社，"人工关节的植入对于严重疾病不能耐受麻醉和手术患者不能施行，或者骨质储备较差患者行植入术由于后期功能性假肢导致关节再植入。"

Aseptic loosening of prosthesis has become the main reason for failure. From the prospect of prosthesis design,increasing the prosthesis and bone adaptation to reduce the initial micromotion and increase long term bone ingrowth is the only way to achieve long term fixation.

而这一密合程度由髓腔形态与假体外形共同决定，因此股骨髓腔形态必须纳入假体设计的考量的中，而研究各种影响髓腔形态的因素就极具价值和意义。

Methods Using double selection in the selection of prosthesis,adjusting the position of the pocket for the prosthesis according to the size of the prosthesis,partial undermining the major pectoral muscle and fixing it to the periost of the costal bone.

应用乳房假体容积双重选择法，根据假体大小适当调节假体放置位置并行胸大肌部分剥离胸骨骨膜固定。

Objective:To explore the security and effect of transabdominal preperitoneal prosthesis by laparoscopy.

目的：探讨腹腔镜经腹膜腹股沟斜疝无张力修补术（transabdominal preperitoneal prosthesis，TAPP）的安全性和有效性。

Anterior-posterior and lateral radiographs of the hip were taken to observe radiotransparent region and sclerosis, prosthesis dislocation, attachment of prosthesis and the femur and prosthesis stability.

常规摄髋关节正侧位X射线片，了解假体与骨界面是否有透光区和硬化带，观察假体是否有移位发生以及假体与股骨的接触情况、假体固定的稳定性。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
