Factors related to long-term outcome after decompressive surgery for ossification of the ligamentum flavum of the thoracic spine

Abstract

Duration of preoperative symptoms represents the most important predictor of long-term surgery-related outcome in patients treated for thoracic OLF. The type of ossified ligamentum flavum, dural adhesion, and simultaneous surgery for coexistent cervical or lumbar lesions do not appear to influence the long-term postoperative prognosis.
