The role of valgus osteotomy with DHS fixation in the management of fracture nonunion of the neck of femur

Background: Management of fracture non-union of the neck of femur is age specific and is quite demanding. There is a need to salvage the femoral headin younger individuals which demands a procedure which suits the requirements. The aim of this study was to evaluate the role of valgus osteotomy with dynamic hip screw fixation(DHS) in the management of these fractures and to compare the results with studies of other authors as available in literature. Methods: This was a prospective study of 15 patients with fracture nonunion of the femoral neck conducted between January 2012 to January 2013 with a follow up period of 3 years. Results: There were 9 males and 6 female patients in our study with the right side being more commonly affected. The mean age of the patients was 45.2 years ranging from 36 to 58 years. All fractures united at the end of 6 months. Post operatively the mean Pauwels angle was 340 while the neck shaft angle was 135.20. There was a significant increase in the Oxford score from a mean of 20.4 preoperatively to 37.9 in the postoperative period. All patients were happy with the procedure and the functional outcome. Conclusions: Valgus osteotomy with DHS fixation is a good option for the management of fracture nonunion of the neck of femur in younger patients where there is a need to salvage the femoral head and it gives good functional results.
