What are the after effects of interbody fusion?

Generally, it takes about 1 year for fusion. Complications of surgery.

There are short-term and long-term complications, short-term complications generally occur within 2 weeks after surgery, that is, during hospitalization, mainly including incision infection, nerve damage, intra-incision hematoma formation, paralysis, cerebrospinal fluid leakage, etc. Incision infections are more common, generally 1 in 15-20 patients may have incision infection, but most infections will be improved by drugs**. However, some infections are more stubborn, and they need to be re-operated to remove the pus inside, and then drain for a few days, using sensitive antibiotics, and it will gradually get better.

Very severe infection, including an abscess at the site of the anterior fusion.

It is necessary to remove both the pus and the fusion, and the surgery will be very large, but this is very rare. There is also a certain incidence of nerve damage, because after the bone is cut during the operation, the nerve inside needs to be exposed, and sometimes the nerve adhesion is very serious, which will cause damage to the nerve, so the patient will have pain, numbness and aggravation after the operation, and even muscle weakness. As long as the nerve is not severed, most patients will be able to return to normal levels after about half a year.

Long-term complications include chronic low back pain, loosening of internal fixation, fusion failure, and the effect of fusion segments on adjacent segments. Because after we fixed the lumbar 4 5, the lumbar vertebrae became 4 segments, which turned out to be 5 lumbar vertebrae with 4 intervertebral discs.

It is common for only 3 intervertebral discs to be able to move, which will cause the pressure on the intervertebral discs of the upper vertebral body to become very large, so it will accelerate the degeneration of its adjacent segments. There are also some elderly people with osteoporosis.

The nails may not grow up after a long time, and they may also loosen. Scientists have developed a lot of new technologies to circumvent it. Turn the patient sideways, enter the intervertebral disc through the lateral approach, and remove the intervertebral disc, so as to avoid the risk of cutting muscles and bones in posterior surgery, which enters from the gap, so the infection rate of surgery, and the incidence of nerve damage with some loose nails will be significantly reduced.

There are also some scholars who are now studying artificial intervertebral discs, which are biomimetic and can provide a certain degree of motion, unlike previous fusion surgeries that killed segments. After the artificial intervertebral disc is inserted, it can produce a certain degree of motion, and at the same time provide its stability, which can preserve the normal mobility of the lumbar spine and reduce cervical spondylosis.

The proportion of occurrences.

This surgery is now relatively mature, and there are generally no sequelae, mainly after lumbar fusion, the activity of the lumbar will be affected to a certain extent, but it does not mean that you can't bend over after fusion, and the other several other intervertebral discs will prolapse and bulge in the future, and the probability of herniation will increase accordingly. This is because after the lumbar intervertebral disc removal bone graft fusion, the upper and lower vertebral bodies where the diseased intervertebral disc is located are fused, and after the fusion, the two vertebral segments are fixed and cannot be moved, while under normal conditions, these two vertebral bodies can be flexion, extension, rotation and other activities through facet joints and intervertebral discs. Although the vertebral body of the lumbar spine has 5 segments, the impact of fusing an intervertebral disc is not great, but it is not very ideal and meets the physiological requirements, so there is currently an artificial intervertebral disc replacement surgery, which can restore the physiological function of the normal intervertebral disc as much as possible.

However, for those who have poor stability of the lumbar vertebrae, it is still a better choice to do this surgery.

The part of the intervertebral disc that compresses the nerve can be removed, and the purpose can be achieved.

However, after spinal fusion, the range of motion between the vertebral segments will be relatively reduced, and the degree of mobility may not be as flexible. Traditionally, the spinal fusion surgery of the intervertebral disc is to remove the patient's intervertebral disc. The herniated cartilage is removed and the patient's bone is inserted to fuse the bone that encloses the two segments of the intervertebral disc.

Because the bones will grow, the waist will be stiff in the future. If it is an artificial proprace, there will be degenerative lesions such as bone spurs, so the intervertebral disc in the affected part will either be removed or lose its function after surgery, and the patient will have weakness or stiffness of the lumbar spine, which will also easily cause subsequent joint degeneration. That is to say, the traditional ** method, after bone fusion, reduces the gravity and cushioning of a intervertebral disc to support the load, and the stability is poor, and for patients with large exercise needs, although the pain is relieved, the range of motion becomes worse.

The spinal fusion surgery procedure involves bone grafting and the "fusion" of multiple spinal segments, through which the spinal movement injury can be repaired, the bad spinal bone can be repaired, etc.

Spinal fusion surgery is one of the traditional methods.

Directly remove the medulla of the lesion part of the lumbar spine, and then put something in to fix the joint!

It is the fusion of two or three vertebral bodies into one.

Hello, it usually takes about 3 months to recover. Eat more lean meats, fish, eggs, milk, legumes, fresh vegetables, fruits, etc., and pay attention to gradually resuming exercise.

This is lumbar spondylolisthesis, which requires surgery**, and there are a lot of segments if it is fixed with 8 nails, and it can be 4 or 6 nails.

I have had lumbar internal fixation, and I haven't recovered for seven months.

No, I've only been doing it for 33 days, and you're doing it there.

Gan Wan has to be cautious, his right leg is better in January, and his left leg hurts, and he doesn't know what to do.

Seven months after lumbar spondylolisthesis surgery, low back pain, how to not fuse.
