Thoracic disc herniation is an uncommon cause of thoracic cord compression. Herniation in this region is of particular importance because of the serious disorders of nervous function which result from anterior compresstion of the spinal cord. Early diagnosis and prompt surgical treatment are imperative because of the progressive and serious neurological deficit which results from delay. Numerous problems remain as to the safest surgical approach to the prolapsed thoracic intervertebral disc. We treated a case of herniated intervertebral disc occuring at Tll–T12 using the anterior approach. The result was favourable.
