Computed Tomographic Diagnosis of Traumatic Atlanto-occipital Rotatory Luxation and Successful Closed Reduction in a Dog
A 12-year-old, female spayed crossbred dog was presented for traumatic injuries sustained after being hit by a car. The dog was non-ambulatory with a right-sided head tilt on presentation, neurological deficits and signs of external trauma centred on the head. A trauma computed tomography was performed which revealed an atlanto-occipital luxation with narrowing of the vertebral canal. This was treated successfully via closed reduction and confirmed with a repeat computed tomography scan. The dog recovered well following the atlanto-occipital luxation reduction, and was ambulatory the day after the reduction, and neurological signs resolved within 2 days.
G.L. was responsible for drafting, editing and compiling the manuscript, and was involved with the case management and assisted with closed reduction. K.M. was responsible for editing the manuscript, literature review and engineering the set-up for and performing the closed reduction. S.H. was responsible for editing the manuscript as well as case management and literature review. R.C. was involved with editing the manuscript and literature review. A.H. was involved with the diagnosis and interpretation of the computed tomography as well as editing the manuscript and literature review.
