BACKGROUND Different bone cements and various cementation techniques can lead to different bone loss in revision surgery. We investigated the degree of tibial bone loss depending on different cements and techniques. METHODS 30 tibia specimens were matched into three groups (10 each). In all cases Genesis II tibia component were implanted. In two groups, the tibia base plate alone was cemented...

Abstract The study uses chemical and mineral admixtures to understand the critical processes affecting cement slurry characteristics, including rheological properties, free water, compressive strength, thickening time. Using alternate replace partially has environmental economic benefits. mechanisms behind effects of on parameters were investigated at different temperatures using cutting-edge e...

BACKGROUND AND PURPOSE Revision surgery for periprosthetic femoral fractures around an unstable cemented femoral stem traditionally requires removal of existing cement. We propose a new technique whereby a well-fixed cement mantle can be retained in cases with simple fractures that can be reduced anatomically when a cemented revision is planned. This technique is well established in femoral ste...

The damage of cement slurry to the reservoir is directly related production oil and gas wells, a problem that must be solved for efficient economic development reservoirs. According characteristics field conditions caused by slurry, this paper analyzes main factors affecting degree damage, puts forward technical index requirements evaluation device, establishes method in case loss injection. re...
