Thoracic degenerarive diseases have many clinical signs and symptoms. In particular when multiple thoracic lesions and complications with cervical or lumbar lesions are suspected, it is often difficult to diagnose their main focus. We clinically investigated 30 patients with thoracic degenerative diseases, with a post-operative follow-up period of over one year.Of the main thoracic lesions, ossification of the yellow ligament (OYL) was found in 18 cases, ossification of the posterior longitudinal ligament (OPLL) was seen in 4, OYL+OPLL in 5, thoracic disc lesions in 2, and spondylosis in 1 case. Patient's ages ranged from 19 to 70 years old (mean, 51.4 years). The duration of symptoms ranged from 2 weeks to 20 years (mean, 5.4 years). The main factors which influenced the prognosis were severity of symptoms and trauma. Average improvement rate with JOA score (by Hirabayashi) was 63.9%.
