Diagnosis of osteoarthritis

Differential diagnosis of osteoarthritis

Providing effective treatment of osteoarthritis and relapse depends largely on the use of standardized approaches to its diagnosis and differential diagnosis. Therefore, in this article the generally accepted in the world practice of differential-diagnostic criteria and assessment standards arthrologic status in patients with osteoarthritis

Diagnosis of osteoporosis in osteoarthritis

Improvement in recent years of specific and sensitive biochemical markers, reflecting the overall rate of bone formation and resorption, significantly improved the noninvasive assessment of bone metabolism in various metabolic bone diseases. As is known, biochemical markers are divided into markers of bone formation and bone resorption.

The clinical diagnosis of osteoarthritis

Considerable progress in the understanding of the pathophysiology and evolution of osteoarthritis led not only to improve the diagnosis of the disease, but also to re-evaluate the methodology and metrology of clinical trials in osteoarthritis. The clinical diagnosis of osteoarthritis is difficult.

Laboratory diagnostics of osteoarthritis

In most cases, patients with osteoarthritis have no changes in blood and urine tests, except for cases of synovitis with significant effusion, when there may be an increase in ESR, hypergammaglobulinemia, an increase in the level of the acute phase indices - CRP, fibrinogen, etc.

Ultrasound of the shoulder joints with osteoarthritis

The shoulder joint is one of the most comfortable for ultrasound, especially because many pathological changes occur in its soft tissues. Because of the low information content of the X-ray method, reflection of soft-tissue changes was allowed by ultrasound along with MRT to become leading in the study of the shoulder joint.

Ultrasound of the hip joints with osteoarthritis

Although MRI is the leading method for the detection of coxarthrosis, ultrasound has the advantage of detecting a small effusion in the hip (even less than 1 ml), as well as disturbances in the condition of the periarticular soft tissues in the early stages of osteoarthrosis.

Ultrasound of knee joints with osteoarthritis

As is known, radiography in most cases allows you to determine the damage to the knee joint with the involvement of bone elements in the pathological process. Often these changes are irreversible, the treatment of such patients is difficult.

Diagnosis of osteoarthritis: radioisotope scintigraphy and thermography

Radioisotope scintigraphy of joints is carried out with the help of osteotropic radiopharmaceuticals (pyrophosphate, phosphon, labeled 99тТс). These drugs actively accumulate in places of active bone and collagen metabolism.

Diagnosis of osteoarthritis: ultrasound examination (ultrasound) of joints

The use of ultrasound (sonography) in rheumatology is a relatively new and promising direction. In the last decade, ultrasound (ultrasound) has been widely used as a visualization technique for examining patients with rheumatic joint diseases, as well as monitoring treatment.

MRI of joint components for osteoarthritis

MRI provides objective and quantitative measurements of subtle, subtle morphological and structural changes in various joint tissues over time and is therefore a more reliable and easily reproducible method that helps monitor the course of osteoarthritis
