Spinal stenosis is often treated with spinal canal decompression + intervertebral implant fusion and internal fixation.
Spinal stenosis is a condition in which the volume of the lumbar spinal canal is reduced due to congenital or acquired osteophytes, ligamentous hypertrophy, etc., and the nerves in the spinal canal are compressed, thus causing a series of symptoms.
The surgical procedure is mainly open or minimally invasive, removing the hyperplasia and ligamentum flavum, removing the disc tissue, and partially or completely removing the laminae to completely relieve the nerve compression; due to the decrease in intervertebral stability caused by the surgery, it is necessary to fuse the upper and lower vertebral bodies, and at the same time, fix the upper and lower vertebrae with pedicle screws to reestablish the stability of the spinal canal and the upper and lower vertebral bodies.
After the end of the internal fixation operation, the incision was rinsed, the instruments and dressings were counted, the wound was drained, and the incision was closed layer by layer.
Due to the proximity of the nerves and spinal cord, spinal stenosis surgery carries a certain degree of risk, and the surgeon in charge of the operation often needs to be experienced, careful and gentle operation, and it is recommended that regular hospitals for consultation.
