Antegrade Intramedullary Screw Fixation for Metacarpal Fractures: A Novel Technique

This article presents an intramedullary fixation method that preserves the articular cartilage of the metacarpal head, minimizes soft tissue disruption, and provides stable fixation by implanting antegrade intramedullary screws through the metacarpal base.
