Abstract We hypothesised that a modified ETO in patients undergoing revision total hip arthroplasty (THA) for treatment of Vancouver B2/B3 peri-prosthetic fractures would be associated with good clinical outcomes. A retrospective review was conducted of 34 patients (mean age 73 years). At mean follow-up of 57 months, the ETO had healed in all patients. Two patients had subsidence of the femoral stem at two and three years postoperatively requiring revision, and one patient had a dislocation 3 months after surgery. The mean Harris Hip Score at the time of the final follow-up was 76.9 (range, 46–95); 23/34 patients had an excellent result, 7/34 a good result, and 4/34 a poor result. We conclude that satisfactory outcomes can be obtained using this technique.
