Combined method of screw and wire fixation for mandibular body fracture in a dog

Background: Mandibular body fracture is one of common injuries among the most common maxillofacial injuries in dogs. The condition may lead to extremely impaired mastication and occlusion. The choice of a suitable fixation method to maintain proper alignment and bone healing is therefore indispensable. This report describes the successful management of a unilateral mandibular body fracture in a mixed breed dog using dual screw fixation combined with interdental wiring. Methods: The patient was a ۲.۵-year-old mixed breed dog that showed mandibular asymmetry. It had difficulty in eating following car accident. A unilateral fracture of the mandibular body was diagnosed by clinical and radiographic examination. The fracture fragments were anatomically aligned using two stainless-steel cortical screws placed on each side of the fracture line and connected with orthopedic wire for stabilization. In addition, interdental wiring was performed between canine teeth the first and second premolars and the first molar to support fixation. Postoperative management included antibiotic therapy, analgesia, and soft diet feeding for two weeks. Results: The fixation maintained perfect alignment throughout the recovery period. The animal regained nearly normal masticatory function within one week post-operation. Conclusion: This case highlights that dual screw fixation along with interdental wiring can be a straightforward, stable, and economical technique for the repair of mandibular body fractures in dogs, thus giving a feasible option to the regular plate fixation method.
