If a liquid occurs in the bursa, then the patient has quite similar clinical symptoms without any dependence on their primary cause. At the patient there is a general symptomatology of an inflammatory affection of the structures with a synovial epithelium (glenohumeral, acromioclavicular joint and sheath of the long head of the biceps):
|pains at rest, mainly at night, ingravescent by the movement|
|an impossibility to lie on the affected side|
|a morning stiffness|
|a restriction of motility|
|rarely also an oedema of the shoulder|
The ultrasound examination is a masterful method for an interception of the liquid in the bursa. But a final determination of the diagnosis is possible after the analysis of the artrocentesis of the bursa.
Rheumatoid affections evoke exudative inflammations at bursae. A filling of the bursa can also occur secondarily after a penetration of the synovial liquid through the capsule of the glenohumeral articulation after its weakness by rheumatoid process, and a permanent expansion of the synovial liquid. In this case we cannot speak about real bursitis, rather about parabursitis, i.e. a presence of the liquid between particular structures without an exact anatomical localization.
