The treatment of thoracic ligamentum flavum ossificans is either conservative or surgical, depending on the severity of the symptoms and the severity of the nerve root compression. For patients with more severe symptoms or more serious nerve root compression caused by ossification of the ligamentum flavum, surgery can generally be taken as the traditional surgical method, the specific operation is to use the traditional large incision for the removal of the whole vertebral plate or half of the vertebral plate, and then carry out a complete decompression of the surgical method, and then after decompression, use pedicle screws to fix the adjacent vertebral body, in order to rebuild the stability of the spinal column. After decompression, the adjacent vertebrae are fixed with pedicle screws in order to reconstruct the stability of the spinal column. For patients with mild symptoms, conservative treatment can be tried, which includes strict bed rest, oral non-steroidal anti-inflammatory drugs, such as Fenbid, Fitalin tablets, or Cilobalox capsules, etc., or intravenous infusion of proprietary Chinese medicines with the effect of activating blood circulation and removing blood stasis, such as Senkyong Glucose, Safflower injection, or Danshen injection, etc. For patients with more severe symptoms, the treatment can also be tried. For patients with severe symptoms, intravenous dexamethasone or mannitol can also be given for a short period of time.
