Background: Non union of femoral neck fracture in young patients is still a problem as they are too young to have hip replacement and other salvage procedures are usually unsatisfactory. Pauwels described valgus osteotomy for nonunion of femoral neck which was used by later surgeons also.
Methods: We report a series of 22 patients of nonunion of femoral neck fracture which were taken up for valgus osteotomy and fixed with 120° double angled dynamic hip screw. Average age of patients was 36.5 yrs. Injury operation interval ranged from 4wks- 32wks. Average follow up was 18 months (12 mths38 mths).
Results: Femoral neck fractures united in 18 patients (82%). Excellent to good results were seen in 70% patients.
Conclusion: 120° double angled dynamic screw plate assembly provides rigid internal fixation after valgus osteotomy and being a more familiar fixation device simplifies the procedure and gives good results.
