Dorsal plate fixation of proximal phalanx (PP) fractures is a conventional approach but interferes with the extensor mechanism and results in stiffness. Biomechanical studies have shown that laterally placed plates on the proximal phalanges are equally stable and rigid. This technique obviates the issue of tendon adhesion and may result in better postoperative range of motion and lower secondary procedures such as removal of implant and tenolysis. The low adoption of this technique may be related to lack of familiarity with the surgical approach. We describe our surgical technique with lateral plating of PP fractures and present our case that lateral plate osteosynthesis is an acceptable surgical fixation option for PP fractures, which extends the hand surgeon's armamentarium for more challenging and comminuted fractures., Competing Interests: Conflicts of Interest and Source of Funding: The authors report no conflicts of interest and no source of funding., (Copyright © 2022 Wolters Kluwer Health, Inc.
