Abstract Patients with complex periprosthetic fracture patterns of the femur may ultimately require amputation. Some authors have described the use of mega-endoprostheses as a salvage procedure. This study reports functional outcome, complications, and implant and patient survival after total femoral replacement (TFR) for salvage of periprosthetic fracture of the femur. A prospective database of 20 consecutive patients who underwent TFR for salvage of a periprosthetic fracture was compiled. Patient demographics, mobility information, and preoperative and postoperative Short Form 12-item Survey (SF-12) and 1-year Toronto Extremity Salvage Score (TESS) data were recorded. Postoperative complications were obtained from the hospital database and patient medical notes. One patient was lost to follow-up and was excluded from analysis. The study included 8 men and 11 women, with a mean age of 68.4 years. No significant difference was noted in the prefracture physical (4.4; P=.13) or mental (0.3; P=.78) component scores of the SF-12 compared with 1-year scores. The TESS at 1 year was 69\%. However, patients were more likely to require a walking aid postoperatively (P<.0001). One-fourth of the patients had a postoperative medical complication. In addition, 1 patient had a dislocation and 2 patients had a periprosthetic infection. The implant survival rate was 86\% at 10 years; however, the 10-year mortality rate was 58\%. Although TFR for salvage of a periprosthetic fracture of the femur offers good functional outcome and implant survival, it is at the expense of postoperative complications, and TFR is associated with a high long-term mortality rate.
