Objective To confirm the reliability and feasi bility of measuring anterior tilt angle of the acetabular cup from plain anteroposterior radiograph s.

目的 证实Riten Pradhan提出的髋臼杯前倾角测量方法的可靠性和可行性。

At first the combined defect was transformed into cavitary defect with metal mesh, then the contained acetabulum was tightly packed with deep-frozen morselized cancellous allograft chips (size 7~10mm), the anatomy of the hip was reconstructed and the cup was inserted after pressurizing the cement directly onto the graft.

采用金属网将非包容性骨缺损转变为包容性骨缺损，然后采用7~10 mm的深低温冷冻骨颗粒，使用打压植骨技术恢复骨量，重建髋关节的正常解剖形态，使用骨水泥将聚乙烯臼杯固定于理想的生物力学位置。

Objective To evaluate the clinical outcome of Zweymuller cementless bicon cup used in THR in patients beyond 75 years old.

目的 评价Zweymuller螺旋臼应用于高龄病例全髓关节置换术的临床疗效。

Their data should be interpreted with some caution because quality of fixation of the different cementless cups varied greatly

但必须意识到不同非骨水泥髋臼杯的固定质量变化很大，这对结果会有一定的影响。

The manner of stress transfer from a cementless acetabular component to the surrounding acetabular bone dictates its initial stability.

应力从非骨水泥型髋臼假体传导至周围骨的方式决定了关节的初期稳定性。

Cementless femoral and acetabular components were designed to provide adequate initial stability and to encourage bone to osseointegrate onto or into the implant.

非骨水泥股骨和髋臼假体的设计目的为提供足够的初始固定和促进骨长入假体或长在假体表面。

When cementless acetabular fixation is used, metal backing is required for skeletal fixation.

采用无骨水泥固定髋臼假体时，需要金属帽作骨性固定。

Objective: To analyze the change of periprosthetic bone mineral density after cementless total hip arthroplasty by dual-energy X-ray absorptiometry.

方 法］对41例全髋关节置换术后患者股骨及髋臼假体周围BMD进行12个月的动态观察，并与23例术后5年以上的患者比较。

This technique can also be applied to acetabular defects when compressed graft is used to fill the defect followed by insertion of either a cemented or cementless acetabular component.19

该技术也能用于髋臼缺损，使用打压的移植物去填充插入骨水泥型或非骨水泥型假体后形成的缺损。

Placement of the acetabular component in a slightly cephalad position allows improed coerage or contact with iable bone.

将髋臼假体放置在轻微向头侧移位的位置可增加其覆盖或与活骨的接触。
