title: Internal fixation of intertrochanteric hip fractures: a clinical comparison of two implant designs.
abstract: OBJECTIVE
  To compare two internal fixation devices clinically in stabilisation of intertrochanteric femur fractures.
  
  
  METHODS
  Eighty-seven patients were randomised upon their admission to the hospital using a sealed envelope method. Forty-five were treated with proximal femur nail antirotation (PFNA) and 42 with reverse less invasive stabilisation system (LISS). The perioperative data were recorded and compared in relation to fracture type.
  
  
  RESULTS
  In each type of fractures, no significant differences were found with respect to the blood loss, the quality of reduction, the time to bony healing, and the Harris hip score between the 2 groups. The mean duration of surgery was significantly longer in reverse LISS group than in PFNA group.
  
  
  CONCLUSIONS
  Both the PFNA and the reversed LISS are effective in the treatment of different types of intertrochanteric femur fractures. PFNA is superior to reverse LISS in terms of surgical time, weight-bearing, and perhaps fluoroscopy time.
