Removal of Well Fixed, Fluted Cementless Femoral Stem. Revisiting The Antegrade Drilling Technique for Easier Stem Extraction.

Abstract

In this study, we aimed to revisit and highlight the technique of antegrade drilling of the femur-stem interface during revision hip arthroplasty for extraction of the fluted cementless tapered stems, and to highlight the risk for femoral comminution with unplanned stem extraction. The unique design of fluted stems creates several stress risers in the femoral cortex, and care should be taken while performing a trochanteric osteotomy for stem extraction in such cases in order to avoid unplanned bone fracture, which could compromise the stability of the new implant.
