title: Low failure rate by means of DLBP fixation of undisplaced femoral neck fractures.
abstract: BACKGROUND
  This study evaluated the clinical results of a new implant in the internal fixation of undisplaced femoral neck fractures.
  
  
  METHODS
  Irrespective of their age, 149 patients with undisplaced (Garden I and II) femoral neck fractures were included in a prospective multicentre clinical cohort study and were treated by internal fixation by means of the Dynamic Locking Blade Plate (DLBP). The mean age was 69 years and the follow-up at least one year.
  
  
  RESULTS
  The DLBP fixation resulted in 6 out of 149 failures caused by AVN (2x), non-union (2x), loss of fixation (3x) or combination of these.
  
  
  CONCLUSIONS
  The fixation of undisplaced femoral neck fractures by the DLBP resulted in a low failure rate of 4 %.
