Mastering the art of cemented femoral stem fixation.
Cemented femoral stem fixation 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. Achieving a uniform cement mantle and minimizing polyethylene wear has been shown to reduce the incidence of fixation failure. This article describes the senior author's (C.S.R.) technique for cemented total hip arthroplasty with particular emphasis on the art of cemented femoral stem fixation and his experience with 3 different cemented stem designs over 30 years. The results of using this cement technique with a modern stem design with a surface roughness of 30 to 40 microinches have produced a 95% survivorship at 10- to 20-year follow-up in patients 60 to 80 years old.
