Deforming osteoarthritis : joint death

Deforming osteoarthritis : joint death
symptoms, risk factors, diagnosis and prognosis of deforming osteoarthritis.

Osteoarthritis, or deforming osteoarthritis (DOA) - a chronic, progressive disease in which the cartilage structure there is an infringement, covering the joint surfaces.This leads to a disruption of function of the joint, its gradual deformation and occurrence of specific clinical symptoms.

Deforming osteoarthritis is 70% of the total number of joint injuries.In 95-97% of cases of sick people over 60 years.

Many are mistaken, considering the appearance of osteoarthritis inevitable sign of aging of the body and joints in particular.

This process can be corrected and can be significantly slowed down.But we must know how and when

Deforming osteoarthritis: the mechanism of development and the main reasons

Normally, joint processes of formation and destruction of cartilage balanced and arthrosis dominated by the processes of destruction of the educational process (recovery) of cartilage.

At the heart of the development of

osteoarthritis is a violation of the synthesis of special-grade cartilage chondrocytes cells.This leads to gradual dehydration and loss of elasticity of the articular cartilage, so the load on the adjacent sections of bones increases.

Bone in this place is sealed (osteosclerosis), articular surfaces are flattened to form a small marginal bone outgrowths (osteophytes).They take the excess load, which contributes to their gradual growth.

simultaneously reduced strength and own joint cartilage, therefore cracking and fragmentation can occur when sudden loads.This process is most common in the knee joints.

All this generally leads to a decrease in range of motion accompanied by compaction and loss of elasticity of the periarticular structures, ligaments, development stiffness.

periodically occurs and secondary inflammation in the joints - arthrosis, arthritis, which contributes not only to changes in the joint cavity, but also in the surrounding tissues, adjacent muscles, where due to inactivity is starting to develop their atrophy.

The exposed from beneath destroy the cartilage surface of the bone closer together, and gradually is their fusion - formed bony ankylosis and it becomes impossible to make movements in the joint.

Deforming osteoarthritis: Risk Factors Genetic factors

  • Women suffer in 10-12 times more often than men, due to the inheritance of the disease in the female line.
  • defective genes are inherited, and the formation of collagen protein involved in the formation of joint cartilage.
  • Congenital diseases of bones and joints are not only to change the form of the joint, but also to a distortion of his work, the deformation of the articular surfaces due to excessive load on them, which causes premature wear of the cartilage and its micro-traumas and the rapid formation of arthrosis.It is found in congenital anomalies (dysplasias) skeleton, flat, asymmetrical pelvis and lower limb development, etc.

acquired during life

  • factors with age (usually after age 40), a reduction in the ability of cartilage cells to the synthesis of high-grade fabrics, is dominated by the processes of its destruction.
  • the years, especially after menopause, it begins to develop osteoporosis, due to the fall in estrogen production, so these processes are much more pronounced in women.
  • Obesity, overweight lead to excessive load on the knee and ankle joints where arthritis develops quickly.
  • acquired diseases of bones and joints (especially arthritis) in the absence of treatment, the conduct of an unhealthy lifestyle will sooner or later lead to the formation of arthrosis.
  • poor circulation, nerve supply, which develop with age impair the metabolism in the joint, and the appearance of pain in the joints when moving forces patients to lead a sedentary lifestyle, which leads to atrophy of the ligament-muscular system and bone osteoporosis.
  • operations on the joints contribute to the development of osteoarthritis, despite its revitalizing effect.

External factors

  • Excessive physical activity contribute to a more rapid deterioration of the joint, cause it to micro-traumas (in sports, weight lifting, with heavy physical labor, etc.).
  • Traumatic injuries of the musculoskeletal system of different nature - acute trauma and micro-traumas during occupational hazard (vibration, lead or other industrial intoxication, forced uncomfortable working conditions, etc.)

main symptoms of osteoarthritis

most often deforming osteoarthritis:manifested by pain that occurs during exercise, crunch in the joint, some stiffness in the morning, a decrease in range of motion, swelling in the joint, and a sense of instability.

Joint pain is enhanced by the development of osteoarthritis - first she is small and appears only during exercise, during a short rest passes, but the longer the disease, the more and more concerned about pain (they often worse at night and weather changes).

In some cases, patients may be very sharp attacks of pain during movement, it may be associated with the appearance of cartilaginous fragments.They are formed in the destruction of articular cartilage, meniscus and may fall between the joint surfaces, be infringed.This causes severe pain, limitation of motion, i.e.there is a "joint blockade".

Sometimes the pain starts to disturb the patient continuously while the joint swells, increases in volume, skin temperature rises above it, the liquid (bursitis) is accumulated in the cavity of the joint and periarticular bags.

But not always correspond to the severity of pain severity and extent of changes in the joints, as well as the duration of the disease existence.In some cases, gradually increasing weakness of ligament-muscular system, there is a feeling the crunch even if the feeling of the joint of the patient, and in patients with severe osteoarthritis this crunch can be heard by others.

localization process in osteoarthritis

Deforming osteoarthritis can develop in almost all joints.But fewer and milder affects the elbow and shoulder and wrist joints.

defeat hip joints (coxarthrosis) and knee (gonarthrosis) runs hard, the pain is often very painful, often in the absence of treatment they develop ankylosis (fusion of the articular ends), there comes a disability.In these cases, joint replacement surgery (installation of an artificial joint) sometimes is the only acceptable method of treatment.

Stifle more often affects women, particularly in overweight.Often in these joints during movement felt the crunch, pain when descending the stairs and after prolonged sitting.Perhaps the formation of Baker's cysts (fluid accumulation in the periarticular bag in the popliteal region) and the development of bursitis (fluid accumulation in the periarticular bags).This complicates the movement of the joints, and pain becomes constant, gradually develops leg muscles atrophy.

With the development of osteoarthritis in women in the interphalangeal joints of the hands often appear dense little painful subcutaneous nodules smaller, which usually does not disappear.

When arthritis in the first metatarsophalangeal joints of the feet flat and there is a cross-axis bending joints (valgus deformity).Protruding into the joints (popularly referred to as "bumps") are becoming a significant problem in the selection and purchase of shoes.

flow deforming osteoarthritis without the appropriate treatment - progressive, with periodic exacerbations and remissions gradually declining.Often, patients are forced to resort to the patient's joint replacement operations on the artificial (endoprosthesis).

diagnosis and degree of osteoarthritis

doctor usually makes the diagnosis based on clinical manifestations and radiological survey data (X-ray, computed tomography), in more complex cases carried ultrasound of the joints and surrounding tissues, as well as MRI (magnetic resonance imaging).

radiologically isolated 4 stage course of osteoarthritis:

  • 1st Art.- The joint space is not narrowed, but has a slight rearrangement of the bone structure articulated bones.
  • 2nd Art.- A slight narrowing of the joint space, the formation of marginal osteophytes, cysts and osteosclerosis.
  • 3rd st.- A significant narrowing of the joint space, the deformation of the joint surfaces with a marked sclerosis and large marginal osteophytes, with cystoid restructuring osteoporotic
  • 4th st.- The joint space is not in whole or in part, the bone substance acetabulum and joint head are connected - a condition called bone ankylosis, joint and as such ceases to exist.
