Whether or not to hit the steel nail in minimally invasive lumbar disc herniation surgery depends on the number of lumbar vertebral segments involved in the lesion and whether or not there is lumbar spine instability and other manifestations. If a single segment lumbar disc herniation, lumbar spine is stable, generally do not need to hit the steel nail; if the lumbar disc multi-segment herniation surgery, will cause lumbar spine instability, then generally need to minimally invasive implantation of steel nails. Minimally invasive lumbar disc herniation surgery, at present, is generally in the intervertebral foramenoscopy under the minimally invasive nucleus pulposus removal surgery, its trauma is relatively small, the spinal stability of the impact is small, its recovery is faster, simply a segment of the lumbar disc herniation surgery, generally do not need to hit the steel nail and so on. Minimally invasive lumbar disc herniation surgery if the multi-segment surgical treatment, or the patient itself has lumbar spine instability, then generally need to hit the steel nail implantation, to maintain the stability of the spine. Specific treatment for herniated lumbar discs should be in accordance with the doctor’s instructions.
