AB  - OBJECTIVE: The aim of the study is to explore the clinical effect of a dynamic 
      condylar screw (DCS) system, medial anatomical buttress plate (MABP), and 
      autogenous iliac bone graft through the Watson-Jones approach in the treatment of 
      femoral neck nonunion. METHODS: This prospective study included 15 patients (12 
      men and 3 women) with nonunion of femoral neck fracture, who were treated with 
      the DCS and MABP with autogenous iliac bone graft through the Watson-Jones 
      approach. The patients were followed up for an average of 16 months (range, 12-24 
      months). RESULTS: All patients achieved bone healing with an average fracture 
      healing time of 3.4 months (2.8-4.6 months). The Harris score significantly 
      increased from 30 +/- 3.9 before the operation to 87.6 +/- 7.9 at the last follow-up, 
      and the visual analogue scale significantly decreased from 4 +/- 1.3 before the 
      operation to 1 +/- 1.7 at the last follow-up. The average limb shortening was 
      reduced from 1.8 cm (range, 0-3.1 cm) before the revision operation to 0.5 cm 
      (range, 0.1-1.3 cm) after the last follow-up. The neck-shaft angle of the injured 
      side was restored from an average of 118 degrees  (range, 108-139 degrees ) before the revision 
      operation to an average of 132 degrees  (range, 127-144 degrees ) at the last follow-up. No 
      collapse of the femoral head, wound infections, screw backout, screw or plate 
      breakages, or nerve injury was found. CONCLUSION: TheDCS and MABP with autogenous 
      iliac bone graft through the Watson-Jones approach is an effective option for the 
      treatment of femoral neck nonunion or delayed healing. THE TRANSLATIONAL 
      POTENTIAL OF THE ARTICLE: This article shows that the application of DCS and MABP 
      provides a rigid fixation at the fracture site to promote bone graft integration 
      and bone union. This new kind of technique could be one option of Hip 
      conservation procedures, just special for young patients with femoral neck 
      nonunion.
