Osteoarthritis refers to diseases that affect the joints.As a result of dystrophic-degenerative processes, cartilage is gradually destroyed and replaced by growing bone tissue.The pathological process is accompanied by pain, limited joint mobility, disruption of its functions, and severe deformation.Approximately 10-25% of the population suffers from arthrosis.After 80 years, almost every person has degenerative disorders in the musculoskeletal system.Most often, the disease affects the most mobile joints (fingers, hip, knee, neck).But sometimes degenerative processes develop in the ankle and shoulder joint.
Factors in the development of the disease
Various reasons trigger destructive processes in the body.The most important are congenital abnormalities of connective tissue.Regular microtrauma of the joints and acute joint diseases contribute to the appearance of arthrosis.Over time, the untreated disease enters a chronic stage with regular exacerbations.
Provoking factors leading to the development of arthrosis are:
- excess weight;
- physical inactivity;
- hormonal disorders;
- atherosclerosis;
- venous insufficiency;
- endocrine disorders;
- genetic predisposition;
- regular and heavy loads on the joints (for example, in weightlifters or people whose profession involves lifting and moving heavy objects).
Under the influence of a provoking factor or several at once, the cells of the cartilage tissue begin to collapse.Gradually, the cartilage becomes thinner, becomes less elastic, then becomes covered with cracks and falls off.The bones at the joint begin to rub against each other.The body launches a compensatory mechanism, as a result of which bone tissue grows on the dilapidated surface.As a result, the joint becomes inactive and becomes deformed.
Species
Arthrosis can be primary, which appears independently, and secondary, which develops as a result of diseases, injuries and deformities of the joints.
Depending on the affected joint, the disease has its name:
- Gonarthrosis affects the knee joint.
- Coxarthrosis is a disease of the hip joint.
- Spondyloarthrosis affects the intervertebral discs of the lumbar, cervical, and thoracic regions.
- Crusarthrosis involves the ankle in the pathological process.
If 3 or more joints are involved in the degenerative process, we are talking about a generalized form.If there are 1-2 joints, this is local arthrosis.
Symptoms
At first, the degenerative process occurs unnoticed.There are no nerve fibers in cartilage, so at the initial stages of development the patient does not even know what destructive processes are taking place in his body.The first signs appear only several years after the start of dystrophic-degenerative processes, when the periosteum under the cartilage is injured or inflammation develops.
At first, there is pain in the limbs after heavy exertion.In the morning or after a long stay at rest, a feeling of stiffness and dull aching pain of not too great intensity occurs.After a short warm-up or exercise, all painful symptoms disappear.Therefore, people do not go to the doctor, considering this to be a common occurrence.Meanwhile, it is at the initial stage that it is much easier to stop the progression of arthrosis.
Over time, all signs intensify.The pain becomes obsessive and constant, it prevents you from sleeping at night.Aches, a feeling of stiffness, the inability to fully work or carry out household chores are becoming more and more disturbing.Aching, twisting pain in the joints and surrounding muscles intensifies in rainy weather.
Most often, arthrosis affects the joints of the lower extremities, so a person quickly gets tired of walking, it is difficult for him to climb stairs or any height, since as a result of the destruction of cartilage tissue, stiffness of the joint is formed.An unsteady gait develops due to limb instability.When bending a joint, an unpleasant crunching sound is heard as the articular surfaces, devoid of cartilage, rub against each other.Patients try to limit the mobility of the diseased joint, so muscle atrophy develops over time.They decrease in volume, and the gait becomes even more unstable.
If arthrosis develops in the joints of the upper extremities, this happens most often after injuries or as a result of chronic arthritis.In this case, bone growths appear on the fingers, and the hands become square in shape.
Clinical symptoms depend on the stage of development of arthrosis:
- Null.
At stage zero, a person is sometimes bothered by slight discomfort.X-ray examination does not reveal any degenerative changes. - Elementary.
When walking for a long time, slight dull pain occurs.The X-ray shows the appearance of small areas of bone defects along the edges of the articular surfaces.When bending the joint, a crunching sound is heard. - Easy.
In the morning there is pain and stiffness.X-rays show osteophytes (single bone growths) along the edges of the joints, narrowing of the joint space. - Moderate.
The moderate stage is considered degenerative.Bones and muscles hurt constantly, especially at night.The joint swells a little.X-ray examination shows an even greater narrowing of the joint space, proliferation of bone growths, and increased bone density. - Heavy.
In the severe stage (deforming), constant aching pain occurs, intensifying with movement.When you try to bend the joint, a rough crunch is heard.The x-ray shows a sharp narrowing of the joint space; the osteophytes have already grown so much that it has led to deformation of the joint and a change in its structure.
Diagnosis and treatment
An orthopedist, rheumatologist, and surgeon are involved in determining the type and stage of degenerative-dystrophic processes in the joints.Diagnosis includes standard blood and urine tests.If necessary, an immunological analysis and examination of intra-articular fluid for the presence of infection are performed.Instrumental studies are carried out (MRI, ultrasound to identify changes in soft periarticular and articular tissues, CT, x-rays to determine changes in bone tissue).
Therapy
The disease cannot be completely stopped.Timely diagnosis and treatment allows you to maintain its mobility and prevent the progression of destruction.
Antispasmodics, NSAIDs, steroid blockades injected into the joint, chondroprotectors, muscle relaxants, vitamin and mineral complexes, drugs to improve trophism in affected tissues, proteolysis inhibitors to slow down the destruction of cartilage and bone tissue are used as medications in the treatment of arthrosis.
Patients with severe pain and an unstable joint are recommended to wear tapes that fix the joint in a normal position using adhesive tapes, orthoses, elastic knee pads or elbow pads.Crutches or canes should be used as support.
Physiotherapy procedures must be prescribed, which include UHF, massage, ozone therapy, electrophoresis and phonophoresis with a solution of painkillers, magnetic therapy, acupuncture, electrical stimulation, darsonvalization, paraffin baths (in the absence of inflammation)
In the later stages of arthrosis, when the tissues are already destroyed and the joints are severely deformed, the only way is surgical intervention:
- Arthroscopy with removal of bone growths, spines and partial replacement of damaged cartilage.
- Endoscopy.This is the replacement of a joint (entirely or only part) with an artificial joint.
- Artodez.The joint is closed and fixed in a comfortable position.Over time, the articular surfaces grow together.
Prevention
Since it is impossible to restore your own joint to a normal physiological state, it is necessary to take measures in advance to prevent this disease.It is especially important to do this if there is a family history of cases of this disease or if you reach the age of over 40 years.
Prevention includes maintaining a normal body mass index and regular exercise.Infectious pathologies and other joint diseases should be treated promptly, hypothermia and prolonged and sudden physical exertion should be avoided.People from risk groups (by age, having a traumatic profession, poor heredity) need to regularly examine their joints using x-rays.
Only timely and adequate treatment helps keep the joint healthy.
