Many people often experience occasional back pain. The reasons for their appearance are very diverse: trauma, neurological diseases against the background of damage to the nervous system. One of the most complex manifestations of diseases associated with back pain is Brown-Séquard syndrome.
Represents a whole complex of both sensory and motor disorders caused by damage to the spinal cord across. The list of conditions and diseases in which this syndrome occurs is quite large. The main and most common cause of its occurrence is a back injury, which can be obtained both as a result of a knife wound and as a result of a blunt object wound. It is not uncommon for Brown-Séquard syndrome to appear as a result of a car accident that resulted in a facet fracture along with displacement.
Much less often, but still, there have been cases of this syndrome due to an extramedullary tumor, disc herniation, epidular hematoma, spinal infarction, or spinal dissectionarteries. But still, the main reason is damage to the spinal cord as a result of a mechanical injury.
Several manifestations are described, the cause of which is the aforementioned syndrome. So, the classic version of it is the following. On the side where the lesion is located, either paresis or paralysis of both legs occurs. There is a deep violation of sensitivity (weight, pressure), as well as the absence of it in the form of numbness in the area of innervation of the segments that were damaged as a result of trauma. On the side that is opposite to the lesion, there is a lack of superficial sensitivity (temperature, pain)
Brown-Sequard Syndrome in the reverse version has the following features. The symptoms in this case are different. On the side that is the site of the focus, there may be a violation of superficial sensitivity, and on the other - paralysis and paresis. The Brown-Séquard symptom is present only on the side of the injury (motor disorders, sensory disorders).
The so-called partial variant of the syndrome differs from those mentioned above in that the symptoms practically do not appear or are noted only in zones.
Such a variety of possible manifestations is explained, first of all, by the localization and nature (wounds, contusions, brain tumors, purulent epiduritis, impaired general spinal circulation) of the lesion.
An integral feature of such a disease as Brown-Séquard syndrome is that against the background of the abovechanges, sensitivity in muscles and joints is preserved. This fact is easily explained by the fact that the cords located behind the spinal cord remain unharmed due to the fact that their blood supply is carried out using the spinal artery.
The above symptoms of Brown-Sequard syndrome are clinically confirmed and have been repeatedly observed in medical practice.
