[Comparative study of adverse events between a posterolateral and a direct lateral approach for uncemented primary hip arthroplasty in patients over 65 years of age with femoral neck fractures]. / Estudio comparativo de los eventos adversos entre el abordaje posterolateral y lateral directo para artroplastía primaria de cadera no cementada en pacientes mayores de 65 años con fracturas del cuello femoral.

INTRODUCTION: Femoral neck fractures represent an important chapter in the practice of Traumatology, due to their high incidence, mainly among patients over 65 years of age; they account for around 65% of surgeries in Traumatology. Early function of patients who sustained a femoral neck fracture is of the utmost importance, as survival decreases within the first 12 months. The purpose of this paper is to compare the intra- and postoperative course of patients who underwent primary hip surgery using Hardinge's direct lateral approach versus Moore's posterolateral approach. MATERIAL AND METHODS: 79 patients over 65 years of age with femur fractures were selected and divided into 2 groups according to the approach used. Hardinge's direct lateral approach was used in 32 patients and Moore's posterolateral approach in 47 patients, from March 2011 to April 2013. RESULTS: Considering the variables studied, a statistically significant difference (p < 0.005) was seen in the number of blood units transfused to patients in whom Hardinge's direct lateral approach was used. CONCLUSIONS: We agree with the literature in that there is a significant difference in the intra- and post-operative course of patients with femur neck fractures managed using Hardinge's direct lateral approach. A statistically significant difference was seen in the number of blood units transfused per patient, something that in our setting represents better resource utilization.
