Purpose:
To evaluate the contribution of principal imaging techniques in diagnosis and treatment in adhesive capsulitis of the shoulder.
Materials And Methods:
In 20 patients presenting adhesive capsulitis of shoulder since mean of 6,7 months, the following examinations were performed: radiographies, angioscintigraphy, MRI as well as an opaque arthrography and a bursography associated with corticosteroid injection. Patients were followed during one year.
Results:
The opaque arthrography was to affirm the adhesive capsulitis for the inclusion of the patients. Radiographies (patchy demineralization) and scintigraphy (hyperfixation) were often pathological. In MRI, T1 fat-saturated sequences after contrast injection almost always showed enhancement of the articular capsula, the synovia, the miscellaneous bone or the sub-acromial bursa. The latter was often modified and retracted at bursography. In 19 of 20 cases, a functional improvement was observed after the opacifications.
Conclusion:
Therapeutic effect of both arthrography and bursography is almost proved. Post contrast MRI confirms presence of vascular troubles in all the shoulder structures even at this advanced stage.
