Abstract
Mastering the Art of Cemented Femoral Stem Fixation: Fixation of cemented femoral stems is reproducible and provides excellent early recovery of hip function in patients 60 to 80 years old. The durability of fixation has been evaluated up to 20 years with 90% survivorship. The mode of failure of fixation of cemented total hip arthroplasty is multi-factorial; however, good cementing techniques and reduction of polyethylene wear have been shown to reduce its incidence. The importance of surface roughness for durability of fixation is controversial. This presentation will describe my personal experience with the cemented femoral stem over 30 years with 3 designs and surface roughness (RA) ranging from 30 to 150 microinches.
Cemented Primary Acetabulum: I am going to present a technique of cementing an all-poly socket. We have looked at our all-poly socket from 1992 to 1998 and the total number of hips are over 1,000, with a follow-up of 2 to 8 years. We have not revised a single socket for fixation failure.
