Dorsal <scp>3D</scp> ‐printed plate stabilisation of atlantoaxial instability associated with atlanto‐occipital overlap in three dogs

Atlantoaxial instability is a common condition in toy breed dogs, sometimes associated with occipital dysplasia. Surgical stabilisation is challenging due to the small bone size and proximity to the spinal cord. This case report describes three dogs treated with a custom 3D-printed dorsal plate for atlantoaxial instability, considering the presence of atlanto-occipital overlap. Each patient underwent pre- and postoperative computed tomography, and follow-up was obtained via telephone for the surviving dogs. The use of a dorsal 3D-printed plate appears to offer a feasible and clinically acceptable option for managing atlantoaxial instability associated with atlanto-occipital overlap, with generally favourable short-term outcomes.
