VALGUSING INTERTROCHANTERIC OSTEOTOMY FOR THE TREATMENT OF FEMORAL NECK NON-UNIONS: REPORT OF 32 CASES

ABSTRACTThe purpose of the present study was to review the results of femoral neck non-unions treatment with valgusing intertrochanteric osteotomy. Methods: Between 1988 and 2003 we treaded thirty two femoral neck non-unions with valgusing osteotomy and fixation. The mean follow-up time was 9.8 years and the mean age was 41.7 years. Results: Twenty eight (87.4%) of the thirty two valgusing osteotomies evolved to femoral neck union, while four cases (12.6%) evolved to total hip arthroplasty. Eight cases evolved to partial osteonecrosis. Conclusions: The valgusing intertrochanteric osteotomy for treating femoral neck non-unions achieved consolidation in 87.4% (28/32). However, only 56.2% (18/32) achieved full recovery of hip function.
