First thoracic disc protrusion.
First thoracic disc protrusion is rare. Only 12 cases have been described. The rarity of the condition is probably due to relative immobility of the spine at this level. The disc protrusion is invariably lateral causing radiculopathy. Antecedent trauma is rare. Horner's syndrome may be an associated feature. Good results follow disc excision using a posterior approach.
