Surgical management of femoral stem revision: cases (C) in alphabetical order. Femoral osteolysis refers to the radiographical assessment of femoral remodelling/osteolysis in Gruen zones, in brackets when bone loss is minimal. Fem Grad refers to femoral grading in accordance with the D'Antonio grading system. Stem revision cementless and monoblock unless otherwise stated, NO stem was not replaced, TFS long tapered fluted stem, SWS single wedge stem, M modular; revision stem length expressed in mm in brackets; bone filler * Mg-HA magnesium doped hydroxyapatite in granules or in paste. ETO extended trochanteric osteotomy.
