DIAGNOSIS AND DIFFERENTIAL DIAGNOSIS OF RA

The clinical picture of RA is very diverse. In some cases, with the presence of characteristic deformities of the joints, the diagnosis can be made “at a distance” at first glance at the patient, in others, the recognition of the disease is extremely difficult when it is necessary to be guided by the rule “wait and watch”.

The task is complicated by the fact that damage to the joints can be in a wide variety of nosological forms (especially infectious and allergic). There are more than 50 different therapeutic diseases in which there is arthritis syndrome (polyarthritis).

The symptomatology of articular lesions is rather non-specific. Therefore, it is sometimes difficult to distinguish polyarthritis as an independent disease from symptomatic polyarthritis, as a syndrome. In such cases, the diagnosis is made by exclusion based on a thorough differential diagnosis. In this case, differential diagnosis is carried out in accordance with the classification of diseases of the joints.

The working classification of diseases of the joints and the musculoskeletal system includes about 100 names of diseases and with syndromes equal to them. Most of these diseases, however, are rare and can relate to casuistry.

In the practical work of a therapist, the most common are only a few joint lesions, which first of all must be borne in mind and between which you should first of all

differential diagnosis. Here is a list of the most important joint lesions most commonly encountered in therapeutic practice.
