ABSTRACT=Background: Postoperative nonunion of femoral neck fracture often needs secondary operation. We report a case of postoperative nonunion of femoral neck fracture treated with teriparatide.
Case presentation: A young male patient with Garden IV femoral neck fracture who had no obvious signs of healing 3 months after percutaneous hollow nail fixation which the fracture line was enlarged and the hollow nail was withdrawn. Bone nonunion healed after 6 months continuous subcutaneous injection of 20 mg/day of teriparatide after the patient refused a secondary surgery. As far as we know, there are no relevant reports yet. 
Conclusions: Teriparatide is expected to treat young patients with a displaced femoral neck fracture who have difficulty in healing before nonunion and avoiding secondary surgery.
