ABSTRACT
Introduction: Loss of bone stock and anatomical alteration of the proximal femur make femoral revision surgery a complex procedure in which the choice of implant will be critical. Our goal is to assess the clinical and radiological results of complete coating Monoblock stems.
Material and methods: Retrospective study of 78 consecutive cases of femoral review surgery intervened by our unit.
Results: The average follow-up was 122 months. The average score on the Harris Hip Score was 81.2 ± 11.4 points. An age of less than 65 years, a minor femoral defect according to Paprosky classification (I, II and IIIA), the existence of a single previous surgery and the non-occurrence of intra or postoperative complications, was associated with better clinical and functional outcomes (p < 0.05).Cumulative survival was 96.7% at age 10 if we consider as failure the removal of the stem by aseptic loosening and 92% if we consider withdrawal for any cause to fail.
Conclusion: Despite the current tendency to use modularity in femoral review surgery and given the results presented, we consider that complete coating monoblock stems provide a firm and stable fixation. However, the worst results in patients with major defects have led to other options being considered.
