Scaphoid Nonunion: Herbert Screw Fixation through Dorsal Approach

Abstract

Results: Ninety-eight of 102 patients (96.1%) showed radiographic union at an average time of 12.7 weeks. Modified Mayo wrist score was 87.5 points in an average. Ninety-two of 102 patinets (91.3%) showed more than good results.There was no major complications. There was no statistically significant difference between the preoperative and postoperative radiolunate angle, scapholunate angle, or height to length scaphoid ratio. Conclusion:Herbert screw fixation through dorsal approach was a reliable method for patients of scaphoid nonuinion to achieve bony union with high functional scores and without major complications.
