If the lumbar disc is still protruding after minimally invasive lumbar disc surgery, it is possible that the protruding disc can not be removed completely due to the inaccurate localization of the diseased cone with the limited field of view of minimally invasive surgery during the operation. In addition, if the lumbar spine is not immobilized after surgery, the disc will continue to herniate into the spinal canal. If symptoms are not obvious, they can be treated conservatively with medications such as aspirin and methylcobalamin. If the compression symptoms of lumbar disc herniation are still obvious after surgery and cannot be relieved by conservative treatment with medication, another surgery may be needed. Surgery can be performed through minimally invasive procedures such as intervertebral foramenoscopy, radiofrequency ablation, and other procedures, as well as traditional open surgery, in which the protruding nucleus pulposus is removed through a second surgery. Appearance of lumbar intervertebral disc after minimally invasive surgery film is still herniated phenomenon, it is recommended to go to the regular hospital in a timely manner, timely treatment.
