Periprosthetic femoral fractures in minimally-invasive anterolateral short stem versus transgluteal straight stem cementless total hip arthroplasty: What are the differences in the femoral and pelvic morphology?

ABSTRACT:

Background

The occurrence of periprosthetic femoral fractures (PFFs) in cementless total hip arthroplasty (THA) might be associated with the proximal femoral morphology and the pelvis. PFFs in short stem THA are associated with an increased Canal Flare Index. PFFs in straight stem THA show a decreased Canal Flare Index. Therefore, this study aims to compare the femoral and pelvic geometry in PFFs between short stem and straight stem THA.

Methods

A retrospective comparative propensity-score matched study was performed. An institutional database of 5358 THAs was screened for early PFFs within the first 90 days after surgery. All cases of 136 PFFs in primary cementless THA were collected and matched, resulting in 67 PFFs in the straight stem and 37 PFFs in the short stem group.
