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. Surgery was performed in two times with a lapse of 12 months between interventions. It was done a minimally invasive transthoracic decompression and intersomatic arthrodesis without instrumentation. The patient presented good neurological recovery without any serious sequelae.
