RESUMEN
OBJECTIVE: To report use of a pinless external fixator (PEF) for unilateral mandibular fractures in 9 equids. STUDY DESIGN: Case series. ANIMALS: Equids (n=9) with unilateral mandibular fractures. METHODS: All fractures were stabilized with the AO/ASIF PEF using a minimum of 4 clamps, under general anesthesia. Fracture configuration, complications, outcome, and owner satisfaction were evaluated. RESULTS: All fractures were stabilized; 2 equids were euthanatized; 1 because of an inability to stand after surgery and 1 because of owner decision after PEF dislodgement. Seven repairs healed with good outcome and owner satisfaction. Complications included dislodgement of the PEF (3), bone sequestration (3), and weight loss (1). Drainage associated with repair resolved after removal of sequestra and clamps. CONCLUSIONS: Stabilization of unilateral mandibular fractures with the PEF in horses was minimally invasive with minimal risk of tooth root interference; however, after care is time consuming. CLINICAL RELEVANCE: PEF is an alternative technique for stabilizing unilateral mandibular fractures in equids.
