Osteochondrosis is a degenerative-dystrophic lesion of the spinal column, which leads to the destruction of intervertebral discs with corresponding consequences. Osteochondrosis "infects" the entire spine, but the symptoms of the disease are most pronounced when the cervical region, as the most mobile, and the lumbar region are affected. The thoracic region suffers the least.
The signs of neck osteochondrosis are very diverse, and they often resemble other diseases, which makes differential diagnosis and early recognition of the pathology difficult. In this article we will look in detail at how osteochondrosis of the cervical spine manifests itself and what will help you suspect this disease.
Degrees of osteochondrosis
Osteochondrosis is a chronic progressive disease that occurs with periods of remissions and exacerbations. Pronounced clinical symptoms do not appear immediately, but after some time, when the degenerative process enters the 2nd or even 3rd stage.
There are only 4 degrees of pathology:
- The initial stage is characterized by pathological changes inside the intervertebral disc. It loses moisture, which leads to degenerative changes, decreased disc height, and cracking of the fibrous capsule. As a rule, there are no signs at this stage. Diagnosis is only possible using an MRI of the spine. This is the most favorable stage for starting treatment, since in this case it is possible to completely restore damaged discs, which cannot be done in the future.
- Osteochondrosis of the 2nd degree is characterized by worsening damage to the intervertebral discs. Their height decreases significantly, which leads to sagging of the spinal muscles and ligaments. All this causes instability of the damaged segment of the spinal column, increased mobility of the vertebrae, their displacement and sliding relative to each other and the spinal axis. As a rule, it is at this stage that the first signs of the disease appear in the form of pain and other signs specific to lesions of the cervical spine.
- In the 3rd stage, protrusions and herniations of intervertebral discs develop. The symptoms of the disease are fully expressed.
- The 4th stage is the final one. In this case, the formation of osteophytes and spinal deformities occurs. The body tries to somehow stabilize the damaged segment of the spine, which is why osteophytes develop, ossification of ligaments and other processes that lead to stabilization of the vertebrae, but, unfortunately, this process is accompanied by vertebral subluxations and various types and degrees of spinal deformities.
The nature of the symptoms of cervical osteochondrosis
Manifestations of osteochondrosis in the cervical spine are associated with 3 mechanisms of the negative impact of this pathology:
- Direct compression of the spinal cord, which runs in the canal of the spinal column. It should be noted that this happens very rarely with an advanced degenerative process and its complications. Compression of the nervous tissue of the spinal cord can be caused by a large intervertebral hernia, which protrudes directly into the lumen of the spinal canal; spinal cord canal stenosis (narrowing) due to degenerative changes; dislocations, subluxations, fractures of damaged vertebrae.
- Negative effect on the structures of the peripheral nervous system (spinal cord roots and nerve fibers) that exit the cervical spine. They can be compressed between adjacent vertebrae or hernial bulges, and can become inflamed and irritated. All this leads to a number of severe symptoms. This is the most common group of signs of cervical osteochondrosis.
- Negative effect on blood vessels that pass near the damaged area of the spine. In particular, one very important arterial vessel is of clinical importance - the vertebral artery, which passes through the openings of the transverse processes of the cervical vertebrae into the cranial cavity and supplies blood to the posterior third of the brain and the cerebellum.
Let us consider in detail each group of mechanisms and what symptoms they cause.
Symptoms Associated with Spinal Cord Injury
As already mentioned, compression of the spinal cord with cervical osteochondrosis is very rare. This is a very serious condition that can cost a person not only his health, but also his life.
Damage to the upper cervical spine is life-threatening. The cardiovascular and respiratory centers suffer, which leads to immediate death. With compression at the level of the 3-4 segment of the spinal cord, tetraplegia develops (paralysis of all limbs and muscles below the injury). The respiratory muscles and diaphragm also suffer, which can lead to respiratory arrest and death.
If damage occurs at the level of the 4th-5th segment of the spinal cord, tetraplegia develops, but without respiratory impairment. When 5-8 segments of the spinal cord are compressed, various muscle groups of the upper extremities suffer and paraparesis of the legs and disruption of the pelvic organs occur.
Symptoms associated with nerve damage
Pain syndrome
First of all, it should be noted the pain syndrome, which can be chronic (cervicalgia) and acute in the form of lumbago (cervicalgia). Pain occurs in the neck, occipital part of the head and shoulder girdle. It is usually caused by irritation, compression and inflammation of the nerve roots of the cervical spine, as well as pathological spasm of the muscles in this area, which are innervated by these nerves.
The pain associated with cervicalgia is almost constant, aching, and varies in intensity. As a rule, the pain syndrome can be tolerated. It appears or intensifies with sudden movements, turns and tilts of the head. Movements in the neck are accompanied by a characteristic crunching sound.
Cervical pain occurs suddenly in the form of a shooting or electric shock. It is very intense, it goes to one of the hands. Lasts a few seconds or minutes, then gives way to cervicalgia. It is usually caused by sudden movement and compression of the nerve.
Radicular syndromes
All major nerves of the upper extremity (median, ulnar and brachial) are formed from nerve fibers that emerge from the cervical spine. Thus, in the presence of cervicobrachial osteochondrosis, these nerve structures may suffer. All these nerves are mixed, that is, they have both sensory and motor functions. Depending on which root is affected, the symptoms will differ. For example, the sensitivity of the 2nd or 3rd fingers may be lost, and paralysis of one or more muscles may occur. All these signs of nerve damage are classified into separate syndromes, which only a neurologist can determine.
Occipital neuralgia
Occipital neuralgia develops when the greater and lesser occipital nerves, which are formed by the 2nd, 3rd and 4th pairs of cervical spinal nerves, are damaged. When these structures are compressed, irritated or inflamed due to a degenerative process in the spine, a headache occurs in the back of the head, which women often complain about.
This pain is so typical that only its description allows a correct diagnosis to be made in 90% of cases. It is also called shooting cranialgia. An attack of pain occurs suddenly, has a unilateral localization (it rarely hurts on both sides), patients compare the nature of the pain to an electric shock. The attack lasts several minutes, but can be repeated several times a day. Pain occurs on the posterolateral surface of the neck and spreads upward to the occipital protuberance (repeats the anatomical course of the occipital nerve). At the same time, a sensitivity disorder in the skin of the back of the head may develop (numbness, crawling sensation).
Cardiac syndrome
This name is due to the fact that this manifestation of osteochondrosis of the cervical spine is very similar to angina pectoris and other heart diseases. The reason for this phenomenon is damage to the nerve fiber that innervates the pectoralis major muscle and the phrenic nerve, the fibers of which are woven into the pericardium of the heart.
The cause of the pain is spasm of the pectoralis major muscle due to pathological impulses along the damaged nerve fiber. At the same time, patients very often confuse such pain with heart pain. Unlike coronary pain, pain syndrome with cervical osteochondrosis has a long duration (sometimes several hours or days), which does not happen with angina pectoris, is not associated with physical activity, but there is a relationship with body position. The pain intensifies with sudden movements, turning the head, coughing, sneezing, which does not happen with angina pectoris. Antianginal drugs (nitroglycerin, etc. ) will not be effective.
Important! In any case, such symptoms require a thorough differential diagnosis, because atypical variants of angina and heart attack also occur. In order not to miss a serious disease, you first need to do an ECG. With osteochondrosis, no pathological changes will be recorded.
Symptoms associated with vertebral artery injury
Compression of the vertebral artery during cervical osteochondrosis can cause a large number of unpleasant manifestations, which are mainly associated with a decrease in blood flow and hypoxia of the part of the brain that is fed by this vessel (the posterior third of the brain and the cerebellum).
Signs of vertebral artery syndrome:
- headache of a diffuse or pulsating nature in the back of the head, temples and parietal region;
- dizziness;
- nausea and vomiting;
- visual disturbances;
- ringing in the ears, decreased hearing acuity;
- impaired coordination and balance;
- development of drop attacks (sudden falls without loss of consciousness due to sudden turns of the head);
- memory impairment, decreased performance, ability to concentrate.
Important to remember! With pronounced changes in the spine, the artery can be compressed so much that this will lead to the development of ischemic stroke in the vertebrobasilar region of the brain. Therefore, it is important to suspect pathology in time and take all necessary measures to improve the health of the spine and prevent further pathological changes.
