Nonunion femoral neck fracture with varus deformity can be a difficult problem to treat, particularly in the young patients and they are associated with high complication rates of avascular necrosis due to the precarious blood supply and poor biomechanics. For improving either biology or biomechanics various treatment options include cannulated screws fixation with washers in inverted triangle configuration, rigid internal fixation with or without bone grafting, muscle pedicle bone graft, valgus osteotomy of the proximal femur with or without bone graft, valgus osteotomy or hip arthroplasty. Valgus osteotomy, repositioning and fixation with dynamic hip screw (DHS) achieved good union rates and good functional outcome with minimal complications by altering the nature of force transmission across the nonunion, shear forces are converted into compressive forces that lead to rapid osseous union without the need for bone grafting.6 Here we are presenting a case of nonunion fracture neck femur in young patient treated with valgus osteotomy stabilized with 140 degree dynamic hip screw.
