Comparison Between Y- and S-Shaped Incisions for Open Reduction and Hook-Plate Fixation of the Mallet Finger

Abstract

Objective:This study evaluates the results of open reduction and hook-plate fixation in the treatment of osseous mallet finger and compares S- and Y-shaped incisions used for the approach.Methods:Twenty-eight patients treated for osseous mallet finger using open reduction and hook-plate fixation were divided into two groups according to their incisions types (group I: S-shaped, n=18; and group II: Y-shaped, n=10). Functional results at the first year of follow-up and complications were evaluated.Results:All fractures healed. In group I, all patients had excellent results; in group II, nine patients had excellent results, and one patient had fair results. The numbers of complications were two in group I and six in group II.Conclusion:Hook-plate fixation is a successful treatment method for osseous mallet finger. The rate of complications can be decreased using an “S-shaped” incision with this technique. However, patients should be informed about possible skin problems and nail deformities.
