Purpose: To evaluate the clinical and radiographic outcomes of scaphoidnonunion patients who had treated by open reduction and internal fixationwith Herbert screw through dorsal approach.
Methods: We reviewed prospectively a series of 102 consecutive patients withscaphoid nonunion (Mack-Lichtman stage I, II, III). All patients were managedwith open reduction with dorsal approach and internal fixation with a Herbertscrew and additional K-wires. Exclusion criteria included conservative treatment,percutaneous fixation, scaphoid nonunion advanced collapse wrist.There were 94 male and 8 female with an average age of 28 years (range, 13-65years). The mean follow period was 35 months (range, 12-96 months).Postoperative radiographs were reviewed to assess the fracture union, carpalalignment, and screw position. Functional results were evaluated by modifiedMayo wrist score.
Results: Ninety-eight of 102 patients (96.1%) showed radiographic union at anaverage time of 12.7 weeks. Modified Mayo wrist score was 87.5 points in anaverage. Ninety-two of 102 patinets (91.3%) showed more than good results.There was no major complications. There was no statistically significant differencebetween the preoperative and postoperative radiolunate angle, scapholunateangle, or height to length scaphoid ratio.
Conclusion: Herbert screw fixation through dorsal approach was a reliablemethod for patients of scaphoid nonuinion to achieve bony union with highfunctional scores and without major complications.
