Clinical Scorecard: Biportal Endoscopic Spinal Surgery for Thoracic Ossification of the Ligamentum Flavum: An Analysis of Surgical Outcomes Across Different Classification Types

At a Glance

CategoryDetail
Condition
Key MechanismsProgressive endochondral ossification leading to spinal stenosis. [Citation needed]
Target Population
Care Setting

Key Highlights

  • Significant improvements in VAS and mJOA scores post-surgery (p < 0.05).
  • No significant differences in recovery rates between fused and non-fused groups (p > 0.05).
  • Fused group showed greater increase in anteroposterior diameter (APD) compared to non-fused group (p < 0.05).
  • Fused group had longer operative times and higher complication rates.

Guideline-Based Recommendations

Diagnosis

    Management

    • Biportal endoscopic spinal surgery (BESS) for symptomatic thoracic OLF. [Citation needed]

    Monitoring & Follow-up

      Risks

        Patient & Prescribing Data

        BESS is effective for both fused and non-fused types.

        Clinical Best Practices

        • Perform BESS under direct visualization.
        • Evaluate complex cases, especially in fused OLF.
