Three-level thoracic disc herniation: transthoracic decompression without fixation.

Thoracic disc herniation is a rare pathology compared to the rest of the herniated discs. Due to their difficult access to the area of compromise and proximity to the spinal cord they represent a real challenge for the spine surgeon. The objective is to report an atypical case with three symptomatic dorsal disc herniations which required surgical treatment.
