Twenty-two herniations of a thoracic disc in nineteen patients were
surgically excised between 1972 and 1984. An anterior transthoracic
decompression or a costotransversectomy was used for all discectomies. Pain
and paraparesis were the most common symptoms preoperatively. The average
length of follow-up was forty-eight months. Sixteen patients had an
excellent or a good result, one had a fair result, and two had a poor
result. Twelve of the fourteen patients who had had motor weakness
preoperatively had varying degrees of improvement in motor function
postoperatively. Pain was relieved in ten patients, reduced in eight, and
unchanged in one. Anterior decompression of herniated thoracic discs
yielded gratifying results, but the procedure is associated with some risk
of damage to the spinal cord. It therefore requires meticulous preoperative
planning and careful surgical technique.
