Comparison of Intramedullary K-Wire Nailing versus Plate for Fixation in Metacarpal Midshaft Fracture

Abstract

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.

Comparative Study between Kirschner Wire versus Mini Plate in Management of Unstable Metacarpal Fractures

“…The end aim of treating any fracture is to restore normal mobility, however there is some disagreement over the best method for stabilizing the fracture [9] . Minimal expense, maximum bone union, and full return of hand function without risk of displacement would characterize the ideal stabilization and fixation approach [10] . Miniplates or Kirschner wires [K-wires] can be employed for internal fixation.…”

Comparison of Miniplate and K-wire in the Treatment of Metacarpal and Phalangeal Fractures

“…The ideal technique for stabilization and fixation would have a minimum cost, maximum bony union, and allow for proper rotation, length, alignment, and recovery of normal hand functioning without fear of displacement [7]. In internal fixation, Kirschner wires (K-wires) or miniplate can be used.…”
