Hip Valgus Osteotomy in Presence of Ipsilateral Femoral Retrograde Nail: A Case Study and Literature Review

Abstract

AbstractHip valgus osteotomy for femoral neck nonunion is a widely popular procedure with high success rates. In the setting of multiply injured patients, with concomitant femoral neck and shaft fractures, a potentially higher incidence of femoral neck nonunion rates may call for a hip valgus osteotomy in the presence of an existing retrograde intramedullary nail, which has not been reported in literature. We revisit the preoperative planning and describe the surgical technique of hip valgus osteotomy in a case of a nonunion of a femoral neck fracture after previous fixation of concomitant femoral shaft and femoral neck fractures using retrograde femoral nail and dynamic hip screw, respectively. Hip valgus osteotomy can be done proximal to a preexisting retrograde femoral nail with careful planning, without limiting the surgical technique or affecting the clinical outcomes, and when using combined fixation for neck shaft fractures certain technical features must be considered.
