2 year old Fox Terrier

April 4, 2016 By Allison Zwingenberger

Today’s case is a 2-year-old male Fox Terrier who was hit by a car. Due to the animal’s injury, only the single lateral projection of the lumbar spine was obtained. What are your findings?

R LAT Spine

Show findings...

Findings

There is a comminuted, oblique fracture of the body of L3. The vertebra is compressed and shortened due to the fracture. The facet joint is luxated, and the floor of the vertebral canal of L3 is at the level of the roof of the canal at L4.

Diagnosis

Fracture/luxation at L3-4.

Discussion

There is a comminuted fracture of the L3 vertebra as well as a luxation of L3-L4. This instability resulted in severe spinal myelomalacia that was found at post mortem. It is contraindicated to position the animal in dorsal recumbency in an unstable spine because of the risk of further spinal cord trauma. Orthogonal views can sometimes be obtained with a cross-table technique.
