Thoracic ossification of the flavum ligament is a rare cause of posterior spinal cord compression. The only treatment for this pathology is surgical resection of the ossified flavum ligament to decompress the spinal cord through a laminectomy. A 65-year-old male patient had become increasingly difficult to walk and fall easily for a year, and the symptoms were worse. The diagnosis was thoracic ossification of the flavum ligament in two levels T8-9 and T10-11. He has undergone minimally invasive laminectomy with a tubular retractor system, microsurgery scope, and high-speed drill at the NeuroSpine Unit [Hidden name of Affiliation]. Ossification of the flavum ligament of the thoracic spine is a rare cause of myelopathy. Deficit of the lower extremities without hyperreflexia is often overshadowed by other disorders of the lumbar level or caudal nerve roots. Minimally invasive laminectomy with a tubular retractor system, thus offering several advantages. Preservation of these structures theoretically reduces the likelihood of developing spinal instability. Minimally invasive laminectomy treated TOFL allows complete decompression with minimal damage to important spinal structures.
