Intervertebral disc herniation at D3-4 Case report.

The authors report a case of intervertebral disc herniation at D3.4 which they removed surgically from a posterior approach. They emphasize the extreme rarity of this localisation. The hernia was calcified, extruded and displaced posterolaterally and medially, causing pressure on the anterior aspect of the spinal cord with neurological signs of the pareto-spastic type. The operation was successful, with relief of pain and regression of the neurological symptoms.
