7mo FS Poodle cross with pain and T3–L3 neurologic deficits immediately after being hit with a pick‐axe. A lateral thoracic spinal
radiograph shows a Salter–Harris type 1 fracture of the caudal body physis of T5, with concurrent ventral displacement of T6 relative
to T5 (a: arrowhead). These findings are seen on sagittal plane and 3D reformatted CT images (b–d: arrowheads). The T5–6 vertebral
articulations are subluxated (a,c: arrow), and the vertebral canal diameter is reduced, indirectly indicative of spinal cord compression
(b: arrow). The injury was reduced and stabilized surgically.

1y M Chihuahua bitten by another dog 6 days previously. Now has neurologic deficits with neuroanatomical localization to T3–L3. A CT
myelogram was performed. Comminuted fractures of the pedicles (a: arrowheads) and the cranial body (a,b: white arrow) of the 11th
thoracic vertebra are present. T10–T11 intervertebral disk space narrowing and subluxation are also seen (b: arrowhead). Contrast
medium administered intrathecally has absorbed into the spinal cord parenchyma, indicative of myelomalacia (b,c: black arrow). Spinal
cord compression is also evident (a,b).
