Femoral Components
A 68-year-old man requires revision hip arthroplasty for aseptic loosening with significant proximal femoral bone loss (Paprosky IIIA). The surgeon is considering a modular fluted tapered stem with a proximal body to restore offset and version. The patient asks about the advantages and potential complications of modular femoral stems. Regarding modular stems in hip arthroplasty:
