Abstract
Revision after failed THA resulting from loosening of the femoral component can be challenging even for experienced surgeons Aseptic loosening usually is associated with some degree of bone loss We asked whether the Zweymüller SLRPlus® along with allograft reconstruction of the deficient femoral bone stock would provide survivorship osseointegration and stability similar to or better than previously reported implants for femoral revision We retrospectively reviewed 69 selected patients 70 hips who underwent revision of the femoral component using the SLRPlus® stem during a 10year period The indications for revision included aseptic and septic failure of biologic fixation incorrect implantation and periprosthetic fracture Seven patients died and four were lost to followup Fiftyeight of the 69 patients 59 hips were available at a mean 83 ± 27 years range 4–14 years after revision surgery There were 14 men and 44 women mean age 69 years range 42–89 years Four stems 7 were rerevised With rerevision for aseptic reasons the survival at 10 years was 95 95 confidence interval 86–98 No femoral periprosthetic osteolysis occurred around the stem and 91 of stems appeared stable radiographically osseointegration fibrous Based on the survival data we believe the SLRPlus® stems are reliable for patients undergoing hip revision surgery with central bone loss
