Purpose: The purpose of this study was to compare the clinical and radiological results of patients with metacarpal midshaft fracture following surgery using either intramedullary K-wire nailing or internal fixation of plates.
Materials and Methods: This study was conducted with 39 metacarpal midshaft fracture patients between October 2008 and September 2012. Of these 39 patients, 15 patients underwent intramedullary K-wire nailing and 24 patients underwent internal fixation of metal plates. We analyzed bone union time and final posterior angulation radiologically and the range of motion, grip power, and quick-disabilities of the arm, shoulder and hand (DASH) scores, visual analogue scale (VAS) score clinically.
Results: Bone union was observed in all cases and bone union times were not significantly different between the two surgical methods. The final follow-up radiographs showed statistically significant differences in posterior angulation, which was 14°, on average, among the patients who underwent intramedullary K-wire nailing and 5°, on average, among the patients who underwent internal fixation of plates. No significant differences were found for the range of joint motion, power, and quick-DASH scores and VAS score were not significantly different between the two groups.
Conclusion: Intramedullary K-wire nailing showed significant differences in posterior angulations, but both intramedullary K-wire nailing and internal fixation of plates produced good clinical outcomes in the treatment of metacarpal midshaft fracture. Therefore both techniques are considered good treatment methods.
