It can deal with “dry”
synovitis without any presence of exudate
The ultrasound method has its own risks and restrictions during
the examination of synovitis of the glenohumeral articulation as all diagnostic
methods in the area of the glenohumeral articulation have. Problems of the
diagnostics consist in the fact that synovitis is not always connected with the
presence of exudate in the glenohumeral articulation, and it has two reasons:
|
It can deal with “dry”
synovitis without any presence of exudate |
| Under physiological
circumstances the glenohumeral joint can communicate with periarticular
structures through the apertures in the articular capsule. Sometimes through
these apertures during the intensified pressure of a liquid at
exudation in the glenohumeral articulation
the repletion of parabursae takes
place in the area of the glenohumeral articulation. Because this bursa can
be also seen during common ultrasound examination, the examination of the
glenohumeral articulation in the axillary section, which is necessary for
the diagnosis of hydrops, is left out. A liquid along the long head of
biceps is also there at these states. |
We believe that in the case of an indefinite diagnosis on
the ultrasound or a presence of clinic symptoms, which do not eliminate the
glenohumeral synovitis, it is right to examine the patient by MRI or by
arthroscopy which can give us other useful information, also of etiology of
synovitis.
