A novel hook plate fixation technique for the treatment of mallet fractures.

Bony mallet injuries are generally treated nonoperatively, but when the fragment involves a significant percentage of the articular surface, articular incongruity and instability can occur. A number of techniques have been described for the fixation of such fractures and each has its own problems. Anatomic reduction and secure fixation of small fragments can be challenging. Our objective is to describe a new surgical technique using a 1.3-mm hook plate that provides good reduction and stable fixation of a mallet fracture, with early mobilization of the distal interphalangeal joint.
