How does lumbar canal narrow operation do

summary

I've been feeling my waist pain these days. I think it's because I'm too tired recently. I often sit in the office and don't go out for activities. As a result, after a few days' rest, I found that I didn't get better. So I decided to go to the hospital for a check-up. The doctor said I need to have an operation for lumbar spinal stenosis. Today, I'd like to talk with you about how to do lumbar spinal stenosis surgery.

How does lumbar canal narrow operation do

First, standard extensive laminectomy decompression method: in the transverse plane of all the involved spine, the lamina and ligamentum flavum were removed from the outside of the lateral recess. The involved nerve roots were completely decompressed in the whole journey from the beginning of dura to the exit of neural foramen under direct vision, and all the lateral recess with compressed nerve roots were removed Decompression, although the clinical symptoms suggest only single plane stenosis, unilateral nerve root compression. The reason is that spinal stenosis is a multiplanar disease, and the long-term effect of single plane decompression is not ideal.

Second: limited decompression method: selective limited decompression, in order to retain more posterior bone and ligament structure, theoretically, can reduce postoperative spinal instability. The operation of oblique laminectomy, is the lateral anterior laminectomy, selective unilateral or bilateral and plane partial laminectomy or laminoplasty. Methods introduced by mccnloch: posterior median skin incision (5 cm in single plane), after dissociation to both sides, bilateral decompression was performed respectively, generally on the left side first.

Third: the lumbar dorsal fascia was cut in an arc 1 cm from the midline to avoid damaging the interspinous ligament on the spine. The paravertebral muscle was stripped laterally along the interspinous ligament and intervertebral space. The unilateral laminectomy range: up to the starting point of ligamentum flavum and down to the stop point of ligamentum flavum (with the upper 1 / 4 lamina of the lower vertebral body). The medial facet joint was removed to the internal boundary of the vertebral arch to ensure complete decompression under the articular process, and bone graft was performed between the transverse processes. Then, a similar operation was performed on the other side. This technique of preserving supraspinous, spinous process and interspinous ligament is called fenestration decompression.

matters needing attention

Lumbar spinal stenosis surgery is also a surgery that requires the ability of doctors, because the lumbar spine is more sensitive, which is different from other parts of the body. Once the operation fails, it will cause very serious consequences. Therefore, we must be careful when doing lumbar spinal stenosis.
