title: [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].
abstract: BACKGROUND
  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.
  
  
  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.
