title: [Biaxial reconstruction nail for pertrochanteric femoral fractures. Osteosynthesis].
abstract: BACKGROUND
  The steady rise in life expectancy of our population leads to an exponential increase in proximal femoral fractures. The growing increase of comorbidities in these patients requires continuous development of modern implant systems for internal fixation of proximal femoral fractures.
  
  
  METHODS
  In this study we enrolled 116 patients with pertrochanteric femoral fractures who were treated with a proximal femoral nail (Targon PF, Aesculap) over a period of 1 year. The indications for this implant system were set at unstable fracture types. Data of the operative and postoperative course were collected prospectively.
  
  
  RESULTS
  The average age of the 116 predominantly female subjects was 77±14 years and the most commonly observed fracture subtype was 31-A1.2. The follow-up rate was 55 %. We observed a decrease in the postoperative modified Harris hip score of 22.7 %. The 1-year mortality was 21.6 %.
  
  
  CONCLUSIONS
  The results of this study showed a low rate of perioperative complications and implant loss anda decline in patient mobility was typically observed within 1 year.
