Dorsal (dorsal) protrusion of the intervertebral discs

loading...

The Dorsal (dorsal) diffuse protrusion – a bulging disc in the cavity of the spinal canal by up to 5 mm in several divisions of the vertebral column at the same time (without breaking the fibrous ring). Pathology is very dangerous, because over time leads to herniation and compression of the nerve roots.

causes of herniated discs

The Most frequent causes of dorsal protrusion:

  • Physical (spinal injury);
  • Vascular (blood supply disturbance in the segments of the spinal column);
  • Infectious (inflammatory changes of the spine);
  • Allergic (damage to cartilage as a result of an allergic reaction);
  • Hereditary (malformations of the vertebral column).

The Dorsal protrusion is more common in the cervical (C5-C6) and lumbar (segments L3-L4, L4-L5, L5-S1) spinal segments.

Symptoms of dorsal protrusion

Posterior prolapse of the intervertebral disc without rupture of the fibrous ring is accompanied by a set of symptoms:

  • Pain is the first symptom of the pathology of the spine. With dorsal protrusion, it is usually aching. Pathology occurs due to irritation of nerve endings located in the ligaments, muscles and the Dura mater;
  • Stiffness in the morning;
  • Headaches and dizziness is a standard symptom of the localization of the disease in the cervical spine (levels C5-C6-C7);
  • circulatory disorders when pathology is manifested by discoloration of the skin.

The Dorsal protrusion of the cervical spine (C5-C6-C7) with time is converted to a hernia. It is dangerous circulatory disturbance of the brain. Through the transverse processes of the cervical vertebrae vertebral artery passes. It provides blood flow of approximately 25 structures of the brain. When the rear protrusion of the likely compression of the vessel.

Localization of dorsal protrusion at level of C5-C6 due to increased mobility of this segment of the cervical spine. This happens when a person spends a long time on the computer and neck exposed to a strong load.

When the protrusion of intervertebral disc in the cervical spine generated pain radiating to the upper limb. Lumbar localization is accompanied by aching in the lower back and legs. These manifestations are due to irritation of nervous receptors of the ligamentous-muscular apparatus the protrusion of nucleus pulposus.

The Dorsal protrusion of the disk is classified into:

  • Diffuse
  • Circular.

Diffuse protrusion is an uneven loss of the intervertebral discs at several levels of the spine.

The Circular protrusion is a uniform output of the intervertebral disc beyond the functional segment. This pathology is the most dangerous. If it is localized in the lumbar segment, it causes lumbago, sacralgia and cocciglia.

Localization of protrusion in the cervical spine (C5-C6-C7) forms thoracalgia, cervicalgia and tenderness in the intercostal spaces.

Pain syndromes of the rear protrusion:

  • back pain – a sharp pain in the lumbar region. It is accompanied by limited mobility of the extremities, and changes in the structure of the vertebral column. To herniated disc appeared lumbago, you need a strong nerve compression;
  • Sacralgia – pain in the sacrum, worse when standing. It is formed with the localization of the protrusions in the segments L4-L5-S1
  • Cocciglia manifested by numbness and loss of sensation in the coccyx area. Pain aggravated by defecation, and also in the standing position;
  • Cervicalgia – pain in the neck, which are aggravated by flexion and extension of the head;
  • Torakalgiya – pain in the chest that resemble angina or myocardial infarction. Usually observed in patients with severe dorsal protrusion of C5-C6-C7.

Diagnosis of posterior protrusion

Once the clinical examination is rarely accompanied by a diagnosis of dorsal protrusion. Because the size of the loss is small in the initial stages they do not cause pronounced clinical signs of the disease.

To Suspect a pathological condition at the level of C5-C6-C7 in the cervical spine on the basis of neurological symptoms:

  • muscle spasms of the neck;
  • Twitching eye
  • Violation of focus of view;
  • Local pain duringthe feeling of the neck;
  • Numbness and tingling the tips of your fingers.

Methods Medical diagnosis the protrusion of intervertebral discs:

  • Magnetic resonance imaging (MRI) is the most popular method of diagnosis of spinal pathology. It allows to estimate the degree of damage, measure the dimensions of the epidural space.
  • Functional radiographs (made in a state of flexion and extension).

If you are diagnosis of the cervical spine if you suspect a protrusion in segment C5-C6-C7, the doctor is able to assess the mobility of the vertebrae.

  • tomographic imaging is layer-by-layer study of the spinal cord using x-rays.
  • Spondilography – is a combination of conventional radiography of the spine with contrast of the urinary tract.
  • Myelography – method study of the spinal canal by introducing into the spinal canal of a contrast agent.
  • Echosonography – ultrasound examination of the spine, which is used to detect abnormalities of the structure of the vertebral column.
  • Epiduroscopy – the study of the spinal canal by introducing contrast medium into the epidural space.
  • Venopuncture – a method of imaging the venous systems of the spine. Its essence lies in the introduction of contrast medium into the veins near the area of spinal cord compression by protrusion or hernia.

The Use of indiacontrary based on the fact that any damage of the spinal cord is accompanied by compression of nerve trunks.

  • Radioisotope scanning of the skeleton involves the introduction into the blood is a special substance, which accumulates in bone and cartilage. The method allows to detect the presence of tumors and other pathological entities.
  • Discography introduction of contrast into the intervertebral disk.

Effective treatments for

The Correct way to treat dorsal protrusion can be assessed by the doctor. Using drugs cannot restore cartilage. The best way to strengthen the intervertebral discs is therapeutic exercise.

In a medical hospital may be conducted by stretching the spine. It is necessary to increase spaces between the vertebrae which helps to eliminate compression of the nerve fibers.

Thus, the dorsal (posterior) protrusion of the intervertebral disc is a complex pathology. It requires a comprehensive approach to the identification of the causes and treatments of the disease. Especially carefully it is necessary to treat loss in the segments C5-C6-C7, L4-L5-S1.
