Risk Factors for Subsidence of Modular Fluted Tapered Stems Used During Revision Total Hip Arthroplasty for Periprosthetic Hip Fractures.

Background: The objective of this study was to review Vancouver B and B periprosthetic hip fractures treated with uncemented modular fluted tapered stems to analyze survivorship, risk factors for stem subsidence, and clinical outcomes.

Methods: We identified 61 Vancouver B and B periprosthetic hip fractures treated with modular fluted tapered implants. Survivorship, radiographic outcomes, and clinical outcomes were assessed.
