  Objective: To evaluate the progression of Ossification of Ligamentum Flavum (OLF) in the thoracic spine based on cross-sectional Computed Tomography (CT) comparisons. Method: OLF in spinal segments that did not require surgery because there were no cord compression of 17 patients who underwent laminectomies for treating symptomatic OLF were retrospectively reviewed (mean follow-up 6.3 years). Initial (preoperative or postoperative but before discharge) and final follow-up canal area unoccupied ratio (CAUR) of no-operated OLF were compared to evaluate the progression of OLF. Factors influencing OLF progression were also analyzed. Two-year follow-up and final follow-up results were assessed to evaluate the influence of OLF progression on long-term outcomes. Result: Sixty OLF levels were compared between initial and f.. Read More»
