What are the sequelae of lumbar spinal stenosis surgery

Humans are vertebrate creatures, which means that the human body must rely on the power of the spine to complete functions such as upright walking. The spine has a very strong bearing capacity, but excessive force or prolonged overload can also cause spinal diseases. For example, spinal stenosis is a more serious disease that can be treated with surgery, but some complications will occur after the operation. So, what are the sequelae of lumbar spinal stenosis surgery?

1. The sequelae of lumbar spinal stenosis surgery include infection. After surgery, surgical incision infection can also lead to intervertebral disc infection. The main symptoms are: the original neuralgia and back and leg pain subsides, but after 5 to 14 days, the back pain, buttocks or lower abdominal cramps and muscle spasms reappear. The patient is unable to turn over by himself and is in great pain. Nerve damage. During the operation, the patient's epidural and endodural membranes may be damaged. Another postoperative complication of lumbar spinal stenosis surgery is damage to large blood vessels. The most obvious thing is that during posterior approach surgery, the large blood vessels in the posterior abdominal wall will be damaged.

2. Adhesion and scar. After the nerve roots and lamina at the surgical site are removed, adhesions and scars will appear at the exposed part of the dura mater, causing low back pain and radiating nerve root pain. Scar hyperplasia and adhesion will occur at the bone defect of the posterior wall of the spinal canal, which will lead to stenosis, hematoma organization, adhesion and calcification after surgery. If it is not treated for a long time, the adhesion will become more serious.

3. Another side effect of lumbar spinal stenosis surgery is spinal instability. For some patients, leg pain may subside after surgery, but back pain may still occur. Finally, there is organ damage. If blood vessels are damaged, it may cause damage to other organs, most commonly the bladder, ureters and small intestine.
