Free-ranging common snapping turtles (Chelydra serpentina) are frequently evaluated for traumatic wounds following collision with vehicle undercarriages. One of the most common types of wounds observed are fractures associated with the dentary bone at the mandibular symphysis. Due to the unique anatomy and natural history of this species, stabilization and healing of symphysis fractures can be challenging. This retrospective study details the presentation, treatment, and outcome of traumatic mandibular symphysis fractures in snapping turtles presenting to a wildlife rehabilitation center in Wisconsin. The records of a wildlife center were retrospectively reviewed to identify common snapping turtles diagnosed with mandibular symphysis fractures from 2014 to 2024. Signalment, description, therapeutic approach, and outcome were evaluated. Of the turtles that were evaluated, most fractures were classified as full-thickness dentary bone fractures located at the mandibular symphysis. Fractures were managed using external coaptation techniques or internal fixation with wire. One animal received a bone graft coupled with external coaptation. Ancillary treatments included antimicrobial therapy and analgesics. No animals required a feeding tube. Varying levels of fracture healing were appreciated with time to release often 4 months or longer. This study details the challenges associated with techniques that are often successful in other animals. Treatment success is complicated by both aquatic environment and the bite force of these turtles.
