Hearing the diagnosis "Herniated Schmorl ", Not everyone will understand what is at issue, although the notion of a" hernia "is known to many. What is a Schmorl hernia? So they call one of the varieties of hernias.
The hernia of the lumbar spine is diagnosed most often, which is associated with the greatest burden on the vertebrae of the waist.
The most common cause of Schmorl's hernia is genetic predisposition .
The mechanism of formation
Herniated Schmorl The condition at which there is an insertion of a kernel of an intervertebral disk in a body of the next vertebra - the bottom or top is named.
All vertebrae are interconnected by intervertebral discs. In the center of the body of each vertebra is a spongy substance that is covered from the outside with a dense compact bone tissue. The structure of the intervertebral disc is a strong fibrous ring, fused with the bodies of adjacent vertebrae. In the center of the intervertebral disc there is a so-called. pulpous nucleus, it consists of a substance resembling jelly. This gelatinous substance acts as a shock absorber when loaded on the vertebrae - softens and distributes the load on them in a uniform manner.
Due to a change in the structure of the compact substance of the vertebra or the fibrous membrane of the intervertebral disc, the nucleus pulposus of the disk moves up or down, as a result of which the nucleus of the disc is implanted into the spongy substance of that vertebra in the direction toward which the displacement occurred. This pathological phenomenon is called the Schmorl hernia.
The causes of
This pathology arises, as already mentioned, most often in the lumbar region, and this is due to the following reasons.
The most common reason for the appearance of a Schmorl hernia is genetic predisposition . The probability of the appearance of pathology in a child is great if one of the parents had a schmoel hernia diagnosed. As a rule, it begins to develop in childhood and during a period of rapid growth in adolescence. The lag in the synthesis of bone tissue leads to the formation of a void in the spongy body of the vertebra. As a result, the closure plate as it falls through the inside of the adjacent vertebra, carrying along the intervertebral disk.
Symptoms of Schmorl's hernia in the lumbar region
The formation and development of Schmorl's hernia in the lumbar region, as a rule, occurs almost without symptoms, especially if its dimensions are not large. But sometimes it can still there is a slight and unstable aching pain in the lumbar region, especially after a heavy or prolonged strain on the spine. A cartilage nodule of may appear. .
If the Schmorl hernia grows, it usually begins to flow into the spinal canal. In this case, there are (but not always) symptoms in the lower extremities of the motor muscles - there are parrezes . Also the person can feel numbness and a little pain, which is quite rare.
Since the hernia of the lumbar spine almost does not manifest itself, she often becomes an accidental finding in the diagnosis of back pain of an unknown origin.
Is Schmorl's hernia dangerous?
Hernia is not considered a dangerous disease, and at any age with normal bone tissue structure it does not lead to injuries or other diseases of the spine. Still, Schmorl's hernia can lead to some serious complications if it is diagnosed late - restriction of mobility, disruption of trophism of surrounding tissues.
