Resumen
BRUNO, Pablo et al. Utilización de tallos femorales porosos extendidos en revisiones de cadera. Rev. Asoc. Argent. Ortop. Traumatol. [online]. 2016, vol.81, n.3, pp.199-205. ISSN 1852-7434.
Introduction: In the set of hip revision surgery there are different options to achieve a stable fixation of the femoral component. The objective of this study was to evaluate the clinical and radiographic outcomes of patients who underwent hip revision with cylindrical extensively porous stem. Methods: Between March 1997 and March 2010 a multicenter retrospective study was performed in 148 patients who underwent hip revision with cylindrical extensively porous stem. The mean age was 63.1 years. Results: The follow-up was 7.7 years. One hundred thirty-four (89.9%) patients achieved a stable bone ingrowth fixation; 12 (8%) a stable fibrous fixation and 3 (2%) a non-stable fixation. The Harris Hip Score improved from 41 points before surgery to 92 points in the postoperative period. Complications included: two deep infections (1.3%), 12 intra-operative femoral fractures (8%) and three hip dislocations (2%). Conclusion: The cylindrical extensively porous femoral stem seems to be a reliable technique for femoral hip revision surgery, as it is possible to obtain a short- and long-term stable fixation.
