Thoracic disc herniation is very rare and the diagnosis is difficult for its variety of the clinical symptoms.
Recently, me experienced three cases of the lower thoracic disc herniation that were treated by transthoracic anterior approach. They all were involved at the lower thracic level and developed low back pain and myelopathy. The dianosis was not established for a relatively long period ranging from seven months to three years after the onset of disease before reforring to our clinic.
All of them were operated upon with transthoracic anterior decompression and fusion resulting in a satisfactory relief of myelopathy and pain.
