Comparación del daño tisular entre los abordajes lateral y anterior para la prótesis total de cadera.

Introduction: The objective was to compare the tissue damage caused by the anterior and lateral approaches for a total hip replacement. Methods: Prospective cohort study comparing patients undergoing total hip replacement using an anterior or lateral approach. Tissue damage was assessed by serum levels of interleukin, tumor necrosis factor, and acute-phase reactants, and magnetic resonance imaging. Function was assessed with the Harris hip scale. Results: The parameters of tissue damage were significantly higher early with the lateral approach, although equalizing towards 30 postoperative days. There were no significant differences in functional outcome at 3 and 12 months. Conclusion: Although the lateral approach presents greater tissue damage in the early postoperative period, the functional outcome and speed of recovery in the short-term are similar between both approaches.
