Patients with lumbar disc herniation generally require surgery when the following conditions occur: A. Acute attack with obvious cauda equina symptoms. That is, the patient suddenly develops severe sciatica, sensory impairment, and dysfunction of urination and defecation, requiring urgent surgery to remove the disc. B, the diagnosis is obvious: those who have been ineffective by regular systematic non-surgical therapy should receive surgical treatment to reduce pain. C. Those with recurrent symptoms, some patients with significant symptoms that are relieved by non-surgical treatment and then reappear in less than 6-8 weeks, and whose daily life is seriously affected, may be considered for surgical treatment. D. Those with progressive development of the disease and obvious neurological symptoms. If the patient’s condition worsens, there is muscle weakness, continuous numbness or even foot drop in the innervated area, physical signs of nerve damage, combined with CT, imaging and other examinations of nerve root compression and symptoms, early surgical treatment should be performed. E. Patients with combined lumbar spinal stenosis of other causes, requiring spinal canal surgery for exploration. In short, surgery should be considered only after regular and systematic non-surgical treatment before surgery, which is really ineffective and seriously affects daily work and life.
