    The study evaluated the clinical effectiveness of biportal endoscopic spinal surgery (BESS) for thoracic ossification of the ligamentum flavum (OLF).

  • 2

    A total of 37 patients were reviewed, divided into non-fused and fused groups, with significant improvements in VAS and mJOA scores for both.

  • 3

    The fused group exhibited a significantly greater increase in anteroposterior diameter compared to the non-fused group, while cross-sectional area changes were similar.

  • 4

    Longer operative times and a higher incidence of complications were observed in the fused group compared to the non-fused group.

  • 5

    BESS produced comparable short-term clinical outcomes for both fused and non-fused thoracic OLF, emphasizing the need for careful patient evaluation.
