title: Evaluation of valgus intertrochanteric osteotomy in neglected fracture neck femur in young adults.
abstract: BACKGROUND
  Femoral neck fractures in young adults have always presented a difficult problem with high rates of non-union and avascular necrosis. At our centre we have been using the traditional Pauwels intertrochanteric osteotomy for neglected un-united femoral neck fractures in young adults. We have made certain modifications in this procedure to suit our resources and so we evaluated the outcome of this procedure at our institute.
  
  
  METHODS
  The study included fifty consecutive cases of neglected femoral neck fractures treated at our centre between February 1996 and October 2012. Patients in whom internal fixation had failed were excluded. The average age of the patients was 37 years (range: 17-55 years). Eleven of the patients were female & Thirty-nine were male. Fifteen patients belonged to Pauwels grade 1, Twenty-six patients belonged to grade 2, and nine belonged to grade 3. The interval between the injury and operation ranged from 1 to 12months (average: 4.3 months). The cases were operated on a normal table using a Watson Jones Approach. The fracture ends were freshened and fixed using a 6.5mm screw followed by a valgus osteotomy which was fixed by a double angle (120 degree) blade plate.
  
  
  RESULTS
  A fracture union rate of 90% (45 cases) was achieved. Two of the healed cases developed avascular necrosis. Results were graded using Askin and Bryan's criteria. Overall, an excellent result was seen in 35 patients, good in 5, fair in 5 and poor in 5. Of the five patients having poor result (3 non-union, 1 implant breakage, 1 implant cut out), two refused revision surgery. In remaining three, one underwent total hip arthroplasty and in two revision osteotomy was performed.
  
  
  CONCLUSIONS
  We believe that intertrochanteric osteotomy provides a good outcome for neglected femoral neck fractures. Performing the procedure on a routine table, with Watson Jones approach and fixing with double angle blade plate is a good option.
