Lumbar disc surgery involves laminectomy, decompression of the intervertebral foramina, removal of the nucleus pulposus, and nerve release. After the anesthesia takes effect, the lumbar disc surgery is performed by lying down on the surgical bed, and then an incision of about 7 cm is made in the back of the lumbar region, separating the paravertebral muscles to reach the soft tissues of the articular eminence. A circular saw is used to cut the lower edge of the vertebral plate to reveal the stopping point of the ligamentum flavum, and part of the bone of the articular eminence is cut to reveal the stopping point of the ligamentum flavum. The proliferated ligamentum flavum and synovial joints were cleaned up and the intervertebral foramina were decompressed. Find the intervertebral disc through the intervertebral space and remove the protruding nucleus pulposus. Observe whether there is bulging of the nerve root, if the local activity is good, consider surgical release completely. The above is the surgical procedure for lumbar disc herniation.
