We studied 22 patients (seven men and fifteen women) with ossification of the posterior longitudinal ligament (OPLL) of the thoracic spine.
Posterior approach was performed on all patients, laminoplasty on nine patients, and laminectomy on thirteen patients. The mean JOA score of all patients improved from 3.6 points to 6.3 points. The improvement rate (Hirabayashimethod) was 35.4%.
In four patients, paralysis of the lower extremities progressed temporarily, but at the end of the study it had improved. In conclusion, satisfactory results were observed by posterior surgical procedure for thoracic OPLL.
