title: [Osteosynthesis of per- and subtrochanteric fractures by blade plate versus gamma nail. A randomized prospective study].
abstract: OBJECTIVE
  To compare clinical and radiological results in per- and subtrochanteric fractures' management with 90 degrees blade plate or Gamma nail fixation; an implant allowing early weight-bearing and fracture healing in correct position remains still difficult.
  
  
  METHODS
  Between 1993 and 1995, 26 patients addressed to our Center for a Kyle IV [1] fracture were divided into 2 groups, one fixed with blade plate and the other with Gamma nail. The follow-up for all patients is 12 months.
  
  
  RESULTS
  Gamma nail allows early weight-bearing in all patients, fracture healing is acquired at 4.2 months; an operative diaphyseal fracture needed conversion to a long Gamma nail. We observed a slight cut-out that didn't need reoperation. In the blade plate group, we noticed three femoral head necrosis without major flattening, two non-unions, one plate's breakage and two malunions; fracture healing is acquired at 6.3 months. The two non-unions and the plate's breakage didn't need reoperation because of low functional demand.
  
  
  CONCLUSIONS
  We prefer Gamma nail in per- and subtrochanteric femoral fractures' management, it allows early and fast weight-bearing and fracture healing is acquired in all cases.
