The sequelae of lumbar foraminoscopy for lumbar disc herniation include failure to completely relieve pain, infection at the surgical site, nerve root damage causing increased pain and even paralysis. Foraminoscopy is a minimally invasive procedure that removes the herniated disc under visualization. If the herniated disc is combined with severe osteophytes, it is difficult to remove the osteophytes completely, and it is not possible to completely relieve the nerve compression and completely solve the pain. Failure to use antibiotics in a timely manner to prevent infection or contamination of the incision site after surgery may result in infection of the incision. In severe cases, the incision may not heal for a long time and may even need to be debrided again for treatment. An extremely rare sequela is damage to the nerve roots of the spinal cord during surgery, which may result in permanent and more serious sequelae, even paralysis of one lower limb. Intervertebral foramenoscopy surgery requires a high level of operation, and it is recommended that patients go to the Department of Spinal Surgery of a regular hospital to receive regular treatment.
