Vertebral malformations, observed most commonly in screw tailed breeds, can result in spinal cord compression and hind limb paresis and ataxia. Treatment of the condition may involve conservative cage rest or surgical decompression with stabilization, possibly accompanied by correction of the malangulation. Postoperative recovery is often lengthy and complex, with weeks of intensive supportive care and months of physical therapy. Long term outcome is variable and can be influenced by the degree of compression as well as the speed of onset and duration of neurological injury.
