Introduction: Periprosthetic hip fracture is the third most common cause of hip revision, behind aseptic loosening and infection. Fractures presenting in combination with a loose stem (B2) or poor bone stock (B3) should be revised. Methods: We retrospectively evaluated 38 patients with type B2 and B3 periprosthetic hip fractures that had been treated with distal fixation cementless stem without bone graft or a plate. Follow-up averaged 2.5 years (range 1.5-10). Results: The mean postoperative Harris Hip Score was 69 points (range 57-91). Fracture consolidation was achieved in all patients. Implant survival at last follow-up was 94.8%. Complications were: one (2.6%) stem subsidence, one (2.6%) dislocation, two (5.2%) infections and one (2.6%) hematoma. Conclusion: Hip revision in the set of type B2 and B3 periprosthetic fracture with distal fixation cementless stem without bone graft is an effective technique.
