Stabilization and Long-Term Outcome of a Tibiotarsal Fracture in a Turkey Vulture (Cathartes aura) Using a Supracutaneous Plating Technique

Abstract

AbstractThe aim of this study was to report the successful outcome of a tibiotarsal fracture in a turkey vulture managed with a supracutaneous plating technique. This is a case report study design. A juvenile male turkey vulture (Cathartes aura) was presented unable to walk. Physical exam revealed instability in the left tibiotarsus. Radiographs confirmed a comminuted mid-diaphyseal fracture of the left tibiotarsus. The turkey vulture underwent fracture stabilization using fluoroscopic guidance with a 12-hole 2.4-mm locking compression plate (LCP) placed in a supracutaneous fashion with locking screws proximally and distally. The turkey vulture was ambulatory immediately following surgery, and lameness had resolved by day three. Four weeks postoperatively, radiographs demonstrated loss of cortical bone density, and the construct was dynamized. At 6 weeks postoperatively, radiographs revealed a bridging callus, and all implants were removed. Following an additional 2 weeks of cage rest, recheck radiographs confirmed continued fracture healing and increased cortical density. At week nine, the turkey vulture was transitioned to a pre-release flight cage where the vulture was noted to set flight, land, grasp, walk, and perch normally. The turkey vulture was released 12 weeks postoperatively. This case report documents the successful functional outcome of a closed, comminuted mid-diaphyseal fracture of the tibiotarsus in a minimally invasive manner utilizing a supracutaneous plating technique. Based on a literature search, this is the first report utilizing supracutaneous plating for a tibiotarsal fracture in a turkey vulture.
