Why does osteonecrosis occur and how is it treated?

Chondrolysis is a disease in which degenerative-dystrophic changes in the cartilage tissues of the spine are diagnosed, accompanied by structural and functional disorders of the intervertebral discs.Depending on the location of damaged tissue, osteoarthritis in the cervical, thoracic and lumbar regions is distinguished.

According to medical statistics, symptoms of osteoarthritis are observed in 50-90% of the population.The average age of onset of osteoarthritis is 30-35 years old.Under unfavorable conditions, signs of osteochondrosis may appear earlier, especially with prolonged uneven loading on the back, legs and as a result of injuries.

What is osteonecrosis?

Osteonecrosis is a disease of the spine in which degenerative and dystrophic lesions of the intervertebral discs occur.With the development of osteonecrosis, degenerative-dystrophic lesions spread to the tissues of the vertebrae.

The main sign indicating the development of osteonecrosis is pain in the neck, back and lumbar region;As it progresses, the pain “radiates” to the arms, chest, shoulders, and upper thighs.With negative dynamics of osteoarthritis, muscle tissue atrophy, sensory disorders and dysfunction of internal organs, caused by their compression and displacement.If not treated promptly, osteoarthritis will develop into an incurable condition.

Causes of osteoarthritis

The main factor leading to the development of osteoarthritis is uneven load on the spine.Common causes of improper load distribution are the habit of carrying bags on one shoulder or in one hand, sitting incorrectly, sleeping on too soft mattresses, high pillows and wearing anatomically incorrect shoes.

Other risk factors include physical inactivity, a sedentary lifestyle, being overweight, injuries to the back, lower extremities, flat feet and other disorders of the musculoskeletal system, as well as age-related degenerative processes due to age-related changes in blood supply to the spine.

The following factors may also play a role in the cause of osteoarthritis:

• physical stress of the body;
• neuro-emotional exhaustion;
• metabolic disorders, poisoning, gastrointestinal diseases that prevent the full absorption of nutrients;
• occupational risks, especially working on vibrating floors;
• genetic predisposition;
• poor posture during the period of active growth, scoliosis;
• wearing uncomfortable shoes (tight, high heels);
• prolonged and/or frequent dehydration;
• poor diet, lack of vitamins;
• smoke;
• Pregnancy, especially multiple pregnancy, combined with an underdeveloped musculo-ligamentary apparatus (due to a shift in the body's center of gravity).

Stages of development of osteoarthritis

Osteonecrosis in the dynamics of the disease goes through four stages:

• Stage 1 (grade) osteochondrosis is characterized by the initial pathological stage in the nucleus pulposus of the intervertebral disc.Due to excessive load, dehydration (dehydration) of the nucleus begins, which leads to a decrease in the height of the intervertebral disc and the appearance of cracks in the annulus fibrosus.Symptoms at this stage are usually absent;Minor discomfort may occur over long periods of time in an uncomfortable static position or active movement;
• In stage 2, the height of the intervertebral disc decreases, leading to a decrease in the distance between the vertebrae and sagging of the spinal muscles and ligaments.This increases the mobility of the vertebrae with the affected discs, which is dangerous due to them shifting or slipping.In the second stage of the disease, discomfort and pain occur, especially with certain types of loads, movements, positions;
• Stage 3 (grade) chondrosis is characterized by the formation of prolapses and protrusions of the intervertebral discs, and may be accompanied by subluxation and/or the development of osteoarthritis in the intervertebral joints.With some types of movement, patients may feel stiffness, lack of movement, and may experience tingling and numbness in the limbs.At this stage of osteochondrosis, people clearly feel pain in the back, neck, lumbosacral area or coccyx area, depending on the location of the affected discs;
• At stage 4 of osteonecrosis, the body tries to overcome the consequences of vertebral hypermobility and adapt to the impaired function of the spine.Osteoporosis, new bone formation, improves the fixation of the vertebrae, forming at the points of contact between the vertebrae.However, in some cases, osteoporosis can cause nerve compression and damage to the vertebrae.Fibrous ankylosis begins in the intervertebral discs and joints.In the absence of microtrauma and nerve root compression, symptoms of the disease will gradually decrease.

Symptoms of osteoarthritis

The main symptoms of osteonecrosis are discomfort and/or pain in the neck and back.The severity of sensations and the presence of additional symptoms depend on the stage of the disease.When examining the patient and collecting history, the specialist makes an initial diagnosis, suggesting the presence of osteoarthritis by a detectable curvature of the spine observed in the transverse or longitudinal plane of the spine.Pathologies of the cervical and lumbar intervertebral discs are much more common than degenerative and dystrophic changes in the sternum.

Signs of cartilage degeneration that patients feel include a feeling of periodic or permanent back fatigue, mild or severe pain, depending on the stage of the disease.The pain can be localized in the neck, back, chest, shoulder blades, causing difficulty and limitation of movement of the upper limbs.

The clinical picture of osteoarthritis largely depends on the location of the pathology, the degree of development of the process and the individual characteristics of the patient.Pathology of the intervertebral disc, displacement, protrusion, herniation and development of bone spurs lead to many different consequences.Among the most common causes are disorders of normal blood circulation in tissues, compression of nerve endings, spinal canal dysfunction, edema, fibrosis of tissues and structures.Such consequences can be accompanied by many different symptoms, leading to misdiagnosis of the disease.

The most common and characteristic symptoms of osteonecrosis include:

• pain in the back, neck, lower back, shoulder blades, ribs;
• discomfort, stiffness when moving the body occurs in certain body positions, bending, turning, increased muscle tension;
• numbness in the upper and lower limbs;
• discomfort in muscles and joints, muscle spasms;
• headache, dizziness, increased fatigue;
• pain in the heart area;
• Hand sensitivity is impaired;
• hypotension.

Symptoms of osteoarthritis vary depending on the location of the pathology:

• When cervical spondylosis occurs, pain in the neck, arms and shoulder area predominates, spreading to the scapula and shoulder areas;headache, dizziness, flashing “spots” or spots in front of the eyes and ringing in the ears;
• If the thoracic spine is affected, pain is localized in the chest, heart, inner surface of the shoulder, armpit area, respiratory discomfort, possible difficulty breathing;
• Lumbar spondylosis manifests as lower back pain radiating to the legs, upper thighs or pelvic organs, often accompanied by sexual dysfunction.

Superficial symptoms - back fatigue, pain - may indicate not only the presence of osteoarthritis, but also other diseases or the development of other pathological processes and disorders not related to disc degeneration.The diagnosis of osteoarthritis can only be made by a specialist, and self-medication for such symptoms is unacceptable.

Classification of osteoarthritis

Types of osteoarthritis are distinguished according to several principles.Depending on the location of the pathology, cervical, thoracic, lumbar, sacral or combined types of osteoarthritis are distinguished.According to clinical manifestations, osteochondrosis in various locations is divided into subgroups depending on the identified symptoms and the entire clinical picture.

Osteoarthritis of the cervical spine:

• Depending on the type of reflex syndrome, determine cervical pain, craniocervical pain, brachial neck pain with different manifestations (vegetative-vascular, neurodystrophic, myo-tonal);
• If the radicular syndrome test result is positive, disc damage to the roots of the cervical spine will be diagnosed.

For pathologies at the chest level there are:

• for reflex syndromes - chest pain with vegetative manifestations, neurodystrophy or myotonia;
• due to damage to the root - disc of the thoracic root.

For osteonecrosis at the lumbosacral level, the following are diagnosed:

• depending on the type of reflex syndrome - back pain (lumbago), lumbago, lumbago with vegetative-vascular manifestations, neurodystrophy or myotonia;
• Root syndrome indicates disc damage to the roots of the lumbosacral region;
• radicular vascular syndrome indicates ischemia.

Diagnosis of osteoarthritis

For diagnosis, instrumental examination methods are used:

• X-ray examination of the spine;
• myelography;
• Neurological examination of sensitivity and reflexes.

Additional methods prescribed to differentiate and clarify the diagnosis and stage of pathology include:

• spinal computed tomography (CT);
• nuclear magnetic resonance (NMR);
• magnetic resonance imaging (MRI).

Directions for treatment of osteoarthritis

Treatment is based on a comprehensive approach and, depending on the stage, lasts from 1 to 3 months of intensive treatment and 1 year of supportive measures to consolidate results and prevent relapse.

Treatment for osteoarthritis is carried out in two directions, depending on the level of osteoarthritis and the patient's health condition.Conservative treatment of this disease includes taking medication and performing some exercises.Surgical treatment in almost all situations cannot be the method of first choice and is indicated in the absence of positive dynamics or progression of the disease compared to long-term conservative therapy.

In addition to medical treatments, it is necessary to adhere to general recommendations for osteoarthritis: follow a diet, take the necessary measures to restore function.

Conservative treatment of osteochondrosis

Conservative therapy is aimed at reducing pain, normalizing the function of the spine and preventing negative changes

Conservative treatment of osteonecrosis includes the following types of therapy:

• drug treatment.Drugs for osteoarthritis are used to relieve pain syndromes, inflammatory processes in tissues and normalize the body's metabolism.In case of severe pain syndrome, it is recommended to use drugs that block nerve endings, which also help reduce the severity of myotonia syndrome.The following types of blockade are distinguished: trigger point blockade, intraosseous, facial, paravertebral, epidural;
• physical therapy methods.Physiotherapeutic procedures help reduce pain, increase the effects of medications, and are also used during rehabilitation periods.The most common applications are ultrasound waves, magnetic fields, low frequency currents, and laser beams;
• Physical therapy (physical therapy) and occupational therapy.A set of special exercises, when performed regularly and correctly, will help correct posture, strengthen muscles, ligament apparatus, normalize muscle function, reduce compression of nerve fibers and help prevent complications of osteoarthritis.Methods of exercise therapy and occupational therapy are aimed at normalizing metabolic processes, restoring adequate nutrition to the intervertebral discs, restoring the position of the vertebrae and the intervertebral discs between them, and evenly distributing the load in the musculoskeletal system;
• massage.Manual massage techniques are used to improve blood supply to tissues, reduce muscle spasms and tension, and generally improve blood circulation.Hydromassage as a direction of therapeutic activity, in addition to the listed effects, also helps normalize the activity of the body's nervous system;
• manual therapy.Manual therapy methods are chosen on an individual basis.Targeted effect on the musculoskeletal system of the body improves blood circulation, lymph circulation, improves metabolic processes, helps regulate the mobility of the musculoskeletal system, strengthens the immune system and acts as a means of preventing complications of osteoarthritis;
• traction therapy(traction) of the spine using special equipment.The purpose of manipulations is to increase the space between the vertebrae to normal parameters and correct structural disorders of the spine.

Osteonecrosis: treatment with drugs

In the treatment of osteoarthritis, the drug is aimed at reducing the severity of symptoms, improving blood supply to tissues and their regeneration.Degenerative cartilage disease cannot be cured with medication alone;Therapy must be combined, including exercises, diet and preventive measures.

In the absence of pronounced and painful dystrophic changes, taking the drug without a specialist's prescription can be considered unjustified.

Drugs used to relieve pain and treat osteoarthritis:

• anti-inflammatory group;
• Antioxidant preparations: vitamin C (in the form of ascorbic acid), E (tocopherol acetate), N (thioctic acid);
• substances that improve blood supply to tissues, B vitamins (mainly B3);
• preparations to regenerate and/or prevent cartilage degeneration, hyaluronic acid.

The drug can be prescribed both in the form of ointments and creams for local pain relief as well as for oral and injectable use.

In case of acute complications, drugs are used to block nerve endings.

Osteochondrosis: nutritional diet of the patient

The principles of the diet are based on the need to improve metabolism, provide the body with essential nutrients, vitamins, minerals and include foods rich in antioxidants, polyunsaturated fatty acids and compounds that promote the regeneration of cartilage tissue.The recommended drinking regimen for osteoarthritis is aimed at preventing dehydration of the body, which can negatively affect the affected tissues.You need to eat in small portions, 5-6 times a day.

The basis of the diet is milk and fermented milk products, lean meat, poultry, fish, fresh vegetables, fruits, nuts, cereals and mushrooms.It is especially recommended to include meat and fish jelly, jelly meat, jelly dishes in the diet and use extra virgin olive oil without heat treatment (for salad dressing).

Preferred food processing method: steaming, grilling, boiling.Limit the intake of flour and confectionery products, fatty foods, spicy and salty dishes and spices, canned and smoked foods, rich meat broths, legumes, sugar and fruits with a high sugar content (grapes).During the day, you must drink at least 1.5 liters of liquid, giving priority to clean and mineral water, dried fruit juices, unsweetened fruit drinks and herbal teas.You should limit drinking strong black tea, coffee, sweet carbonated drinks, and alcohol.

Complications of osteoarthritis

Non-compliance with prescribed treatment, avoidance of prolonged visits to the doctor and failure to treat osteoarthritis contribute to the progression of the disease and cause the development of complications, pathologies and new diseases, such as:

• herniated disc (spinal herniation);
• protruding;
• kyphosis;
• radiculitis;
• salt deposits in the space between the vertebrae;
• spinal cord stroke;
• decreased muscle mass in limbs, muscle atrophy due to blood supply disorders;
• lower limb paralysis.

Despite the fact that grade 4 osteoarthritis can occur without symptoms and with severe pain, progressive osteochondrosis is the most dangerous for developing serious complications and can lead to disability for the patient.

Prevent osteoarthritis

The causes of osteochondrosis are mainly related to lack of attention to the body's needs, poor nutrition and excessive stress on the body.To prevent the occurrence of pathological changes in the spine and limit the dynamics of existing osteoarthritis, it is recommended to adhere to the general principles of a healthy lifestyle:

• eliminate the possibility of physical inactivity: moderate sports: gymnastics, running, swimming, cycling, skiing, gymnastics, non-contact wrestling, etc.;
• When working or other activities that require being in a static position for a long time, you must take a break every 45 minutes to warm up to restore blood circulation.If you have to sit for a long time, you should choose suitable chairs and stools that support the spine, ensure correct posture with hands on the table, feet on the floor or a special support, learn how to maintain posture (back straight, shoulders relaxed);
• To sleep at night, you need to choose a mattress with elasticity, preferably orthopedic, with a flat surface, avoid high or too flat pillows;
• if necessary, lift and/or carry heavy objects, avoid jerking when lifting weights from a semi-squat position, use a specialized belt to support the lower back;
• Choosing the right orthopedic shoes: with the right width for the foot, without high heels and timely replacement of shoes will help reduce the load on the spine, which is especially important for women during childbirth.In summer, you should not miss the opportunity to walk barefoot on uneven surfaces;This helps strengthen the muscles of the feet and reduce stress on the musculoskeletal system;
• A proper diet and alcohol intake contribute to overall health and help maintain normal metabolism;
• If you have a tendency to increased emotions and anxiety with a muscle spasm reaction when stressed, you should learn relaxation methods, as well as regularly attend courses on restorative massage.
