Arthritis of the
acromioclavicular articulation is quite usual even if it
does not seem so. Because the acromioclavicular joint is often affected
at the basic rheumatoid affection – rheumatoid arthritis. Arthritis of the
acromioclavicular articulation is possible also at all the other rheumatoid
diseases. Symptoms of arthritis are at the same time similar to the ones at an
affection in the area of acromioclavicular articulation, which is not
inflammatory, i.e. resting pains, pains during moving and a restriction of the
extension of a movement, therefore we cannot determine a diagnosis on the basis
of these symptoms. At most of rheumatoid affections1, with the
exception of rheumatoid arthritis, this articulation is affected separately, the
examination of the patient does not show us other swollen joints, which could
bring us to a diagnosis of rheumatoid etiology. We often met the finding of
arthritis, it means synovitis in the area of the acromioclavicular articulation,
also in the case of X-ray finding of arthrosis of this articulation. Then we are
not able to judge if this synovitis belongs to the picture of arthrosis, or if
it is rather a manifestation of rheumatoid affection. Then a consequential
reality is the fact that the impigement
syndrome was often connected with arthrosis and synovitis of
the acromioclavicular articulation. Also the affection of the acromioclavicular
articulation, after more serious traumas of the shoulder girdle, was frequent.
From the examining techniques it is necessary to direct an
attention to the meaning of the ultrasound examination which is able to find
synovitis in the acromioclavicular
articulation as a bulge of the articular capsule towards the
second side.
