Overview

Retrospective review identifies femoral morphology and stem design as risk factors for fractures in THA, suggesting careful preoperative planning.

Key Points

  • The study aims to identify the incidence and specific risk factors for intraoperative periprosthetic femoral fractures in total hip arthroplasty.
  • Retrospective review of 3137 primary total hip arthroplasties using cementless tapered stems
  • Femoral morphology classified by Dorr types A, B, and C
  • Multivariate regression analysis to identify independent risk factors for fractures
  • Overall incidence of intraoperative periprosthetic femoral fractures was 2.2% (69 hips)
  • Higher incidence of fractures in Dorr type A (3.0%) and type C (4.7%) femurs compared to type B (1.2%)
  • Quadrangular tapered stems associated with a higher risk (OR, 7.382; p < 0.001)
