Femoral revision with a high offset long stem femoral component

In this retrospective study, we evaluated the aspetic loosening rate and initial result of an extensively hypoxyapatite-coated high offset (127°) titanium femoral component in 27 consecutive femoral revisions. Fourteen men and 12 women (mean age, 68 years) were followed for 2 to 7 years. Preoperative, 3 month, 6 month, and yearly follow-ups included Harris Hip Scores and radiographic analysis. In this study group, the femoral stem length was 155 to 205 mm and the distal stem diameter was 12 to 20 mm. Extended trochanteric osteotomies were necessary on 7 cases. At a mean 53 months follow-up, there were no loose femoral components (ie, bone ingrown in all cases) and no subsequent femoral stem revisions. Thus far, this high offset stem has demonstrated an excellent rate of stable bone fixation.
