Uncemented femoral stem design might have an impact on postoperative periprosthetic femur fracture pattern. A Comparison between flat-wedge and dual-wedge stems

Postoperative periprosthetic femur fracture has been reported to be a common cause of failure for primary total hip arthroplasty (THA) [1-4]. These fractures occur more frequently in the early postoperative period, with most occurring in the first 3 to 6 months after surgery [2,5-8]. The early postoperative and long-term incidence of periprosthetic fracture is consistently higher in the uncemented stems than the cemented stems. Cumulative risk of postoperative periprosthetic fracture in uncemented and cemented stems could be up to 7.7% and 2.1% at 20 years, respectively [2,9].
