Clinical Outcome and Biomechanical Analysis of Dynamic Hip Screw Combined with Derotation Screw in Treating Displaced Femoral Neck Fractures Based on Different Reduction Qualities in Young Patients (≤65 Years of Age)

<div>Follow-up of a 63-year-old male patient with FNF. (a) Preoperative AP radiograph. (b) Preoperative lateral radiograph. (c) Radiograph immediately after surgery showing an anatomical reduction of fracture. (d) Radiograph at 4 weeks postoperatively showing the anatomical reduction changed to negative buttress position. (e) AP radiograph at 6 months postoperatively showing femoral neck shortening. (f) Radiograph at 24 months after surgery showing the femoral neck fracture healed in a deformed position.</div>
