Canal stenosis, as the name suggests, is the decrease in the diameters of the lumbar canal where are the final part of the spinal cord and nerve roots of the cauda equina, responsible for movement of the lower limbs and control of sphincters.

These diameters may be normal or congenitally handicapped by a degenerative process.

This degenerative process begins at the age of 45 years. This is a very common process: 95 % of men and 80 % of women over 65 years of clinical stenosis, or radiologically channel

.

The clinical symptoms are essentially the back pain in lower limbs and sensory disturbances such as tingling members as well as the loss of strength after walking more than 100 meters or less and the relief of symptoms when sitting or standing and also to flex the trunk on the pelvis and trunk extending worsening. Therefore, the window is called syndrome because the patient has to stop for a few minutes the symptoms disappear.

Treatment for severe lumbar canal stenosis is the laminectomy, which involves removing the back of the vertebra. Sometimes it is necessary to place pedicle screws.

Recently, this technique can be replaced by another technique which solves the problem and makes the symptoms disappear. It is a very simple intervention, it is an interspinous device placed between the upper and lower vertebra and gradually increases the size of the channel and conduit or hole through which the nerves. This device does not have any complications and intervention is performed in 30 minutes. EI patient is discharged within 24 to 48 hours and two weeks can lead a normal life.

This type of prosthesis also can be used in the treatment of patients with lumbar disc herniations bulky.

lumbar disc herniation

Another type of pathology of the spine is the herniated disc. It is estimated that 80-90 % of people will have back pain at some point in their life. A large percentage of that pain is caused by herniated disc disorder that causes 9 out of 10 back problems.

¿Why operate

?

EI conservative treatment of disc herniation, ie, the non-surgical treatment is effective in some cases. Fortunately, it is estimated that 20 % of hernias are reabsorbed. But there is a 80% of hernias that do not go alone.

Currently, there are multiple therapeutic options, although not in all cases the solution passes through the OR. When the pain does not subside after acute and follow a regimen of rest, surgery is seen as the best option. The microsurgical technique is the most effective in treating herniated discs because it can be applied in all kinds of cases and has a result of 97% success.
