Intramedullary Fixation of Metacarpal Fractures Using Headless Compression Screws

Abstract

Introduction The purpose of this study is to examine the clinical results of retrograde intramedullary headless screw (IMHS) fixation for metacarpal fractures.

Methods A retrospective review was performed on 16 patients with 18 metacarpal fractures who underwent IMHS fixation at a single institution. The average age was 32 years. The indications for surgery included rotational malalignment (five patients), multiple metacarpal fractures (five patients), angular deformity (four patients), and shortening greater than 5 mm (two patients). The average length of follow-up was 19.4 weeks (median 10.2 weeks).

Results Functional outcome was considered excellent in all patients with total active motion in excess of 240 degrees. Active motion was initiated within 1 week of surgery. No secondary surgeries were performed related to a complication of IMHS fixation.

Conclusion IMHS fixation of metacarpal fractures is an efficacious treatment modality for patients with comminution, multiple fractures, malrotation, and those who require rapid mobilization. It obviates the need for immobilization or more extensive plate and screw fixation techniques with excellent clinical results.
