Objective:
To evaluate the population characteristics, historical, clinical, and diagnostic findings; and treatment outcome of dogs with thoracolumbar intervertebral disk disease (IVDD) whose only clinical signs were those of back pain.
Design:
Retrospective case series.
Animals:
Dogs with IVDD and clinical signs of back pain only, without neurologic deficits, in which survey radiography of the vertebral column and diagnostic myelographic studies were performed.
Procedure:
Review of the medical record, evaluation of survey radiographs of the vertebral column, evaluation of myelograms and estimation of apparent extent of spinal cord compression, and follow-up information provided by telephone contact with owners.
Results:
Spinal cord compression was detected on myelography in 20 of 25 (80%) dogs. Treatment included decompressive surgery in 18 of 25 (72%) dogs and all dogs underwent intervertebral disk fenestration. The condition was improved in 24 of 25 (96%) dogs after surgery.
Clinical Implications:
Dogs with thoracolumbar IVDD that have clinical signs of back pain alone, without neurologic deficits, may have substantial compression of the spinal cord.
