Background and Importance: Acute spinal cord injury without an apparent spinal fracture/dislocation in an asymptomatic subject with silent thoracic ossification of the ligamentum flavum (TOLF) is an extremely rare with only seven fully documented example with this specific scenario in the literature.
Case Presentation: A previously healthy middle-aged woman with a history of MRI documented silent TOLF who developed sever weakness of the lower limbs immediately after a minor fall is presented. Repeat MRI revealed appearance of a myelopathy at the site of the preexisting silent T10-T11 OLF. Laminectomy and excision of the O LF result in complete recovery within 6 months.
Conclusion: We believe that our asymptomatic patient should had undergone prophylactic surgical intervention before this catastrophic event. In a survey of medical literature, we found that the presented case is the first example with MRI documented TOLF in its silence period.

- Asymptomatic patients with significant thoracic spinal canal stenosis due to ossification of the ligamentum flavum (OLF) are at the risk of spinal cord injury after trivial traumas.
- If a TOLF with significant canal compromise is detected incidentally in previously asymptomatic subject, prophylactic laminectomy and excision of OLFs is highly recommended.
- An asymptomatic patient with silent TOLF who sustains spinal cord injury following a minor trauma, should undergo decompressive laminectomy with subsequent OLFs removal.
- In patents with incomplete cord injury, laminectomy and excision of OLFs result in good to excellent neurological recovery.
- Even those with complete spinal cord injury may benefit from decompressive surgery.
