What is rheumatoid arthritis of joints. What joints are preferably affected by rheumatoid arthritis? Methods for the diagnosis of arthritis rheumatoid arthritis of joints. Specialists of the ZMRT clinic are told.

Rheumatoid arthritis joints

Diseases of the musculoskeletal system with a similar clinical picture have different nature of origin. The joint syndrome in rheumatoid arthritis is manifested by a symptom complex due to the damage to the anatomical structures of joints, pain, deformation, defigration, limiting movements, changes in the tendon-ligament.

Causes of the articular syndrome during rheumatoid arthritis

RA is a long progressive autoimmune disease with an unknown reason leading to disability. Women are sick more often than men, which is potentially connected with estrogen and progesterone. Important factors for development:

• Congenital – human main histocompatibility genes are located on the short shoulder chromosome 6 and are called HLA (Hunan Leukocyte Antigens). HLA-DRB * 0401 was defined as a risk factor for rheumatoid arthritis
• Environmental – naso-cell infection, childbirth, stress, nicotine intoxication, insolation, constant contact with technical oils, etc.

Symptoms of arthritis syndrome with rheumatoid arthritis

For joint lesions, characteristic:

• symmetry
• Polyarthritis (multiplicity of lesion, more than 4 units), when debut, changes are detected less than in 4 joints – oligoarthritis
• Local signs of inflammation – swelling, local temperature raising, leather redness
• Pain and mobility restriction with active movements
• deformation
• Sound phenomena-screens, attitudes
• amyotrophy

The pain is variable, intensifying after a long holiday and in the morning, leads to stiffness of movements (the symptom is fixed in 90% of patients), passes after gymnastics or intake of the NSAID.

Rheumatoid arthritis of the knee joint is characterized by the addition of a mechanical type of pain – the unpleasant sensations arise when changing the position of the body in space, in the period of exacerbation may be present constantly.

What joints are affected with rheumatoid arthritis

Localization of the articular syndrome:

• Small articulations of brushes
• Small articulations STOP – 5, 4, 3 fingers
• Combination of proximal interfalangthene-phalangeal joints of brushes, plusnefales stop
• large joints (such changes are registered less often)

Development Stages

The development stages of the disease include:

The debut of rheumatoid arthritis, clinical manifestations are different. Paints – from moderate to strong, may be accompanied by a fever, an increase in lymph nodes, hepatoslenomegaly.

Early stage is characterized by:

• lesion 2 and 3 proximal interphalating and plug–phalange joints
• A positive symptom of compression (unbearable pain appears in squeezing or foot)
• spindle-shaped disfiguration of hand brushes

Expanded and final. The progression of the disease leads to the destruction of bone-cartilage tissue, deformation, complete immobility (ankylose).

How to diagnose

Initially, the doctor analyzes the history of the development of the disease, inspects the patient, conducts functional samples, etc.

Lab diagnostics implies a definition:

• Antinucle and rheumatoid factors
• antibodies to cyclic citrulin peptide
• C-reactive protein
• Immunoglobulins A, M, G Blood

Visualization studies: radiography of the modified and symmetric joints of the brush, foot, knee, pelvis, etc.

Signs confirming the diagnosis:

• osteoporosis
• The narrowing of the articular gap
• erosion and uzura (bone defects)
• ankylosis

MRI and Kt. Affected articulations to confirm degradation, sacroileitis. Magnetic-resonant tomography in the assessment of the articular syndrome during the RA is more sensitive to early changes compared with the X-ray methods of diagnosis, it shows the initial manifestations of complications – osteioncase (donomation of the bone area against the background of blood supply disorders).

Arthroscopy.. Endoscopic study is performed for differentiation of injury, Willezno-nodular synovitis, osteoarthrosis, etc.

To which doctor to turn

The attending doctor of patients with the articular syndrome of Non-Fraumatic Genesis is a rheumatologist. Taking into account the diversity of symptoms, patients may apply for a reception to the therapist, surgeon, a general practice doctor who, after the general survey, are sent to a narrow specialist.
