Sub-trochanteric valgus osteotomy for the treatment of non-union of the femur neck fracture

ABSTRACT

To evaluate the outcome [radiographic union and functional] of subtrochanteric valgus osteotomy in younger adults with nonunion of femoral neck fractures. It was an observational study. This study was conducted in the Department of Orthopaedic Jinnah Post Graduate Medical Center during the period from 01-08-2001 to 31-07-2003. Fifteen patients of ages between 18-50 years with nonunion of femoral neck fractures. Valgus subtrochanteric osteotomy was done and fixed with 120° double angle blade plate. Radio-graphic union and functional outcomes were observed on Salvati and Wilson hip score and Harris hip score. Average delay in presentation of patients was 9 months [range 2-30months]. At an average follow up of 13.5 months non-united neck fractures in 11[73%] out of 15 patients united. In these patients average Harris hip score was 88 and Salvati. In 3[%] patients severe head collapse developed after surgery and in 1 [%] patient fracture remained non united due to broken plate. For an active young patient with non-united or neglected femoral neck fracture, subtrochanteric val-gus osteotomy provides satisfactory results even in early stages of avascular necrosis of head of femur
