Adhesive capsulitis of the shoulder: therapeutic contribution of subacromial bursography.

Objective: To demonstrate the therapeutic value of subacromial bursography (with a steroid injection) in adhesive capsulitis of the shoulder inadequately improved by arthrographic glenohumeral distension with steroid injection.

Method: Twenty cases of adhesive capsulitis documented by glenohumeral arthrography were studied prospectively. A steroid was injected during distension arthrography, which was followed by physical therapy. Subacromial bursography without steroid injection was done routinely for diagnostic purposes. Constant's simplified score and range of motion were determined in each patient at baseline and after one, three, six and 12 months. Patients who were inadequately improved after one to three months underwent repeat subacromial bursography with steroid injection, followed by physical therapy.

Results: Of the 20 patients, 13 were noticeably improved 1.7 months on average after the distension arthrography. Of the remaining seven patients, six were improved 0.7 months on average after the bursography with steroid injection.

Conclusion: Glenohumeral distension arthrography with steroid injection followed by physical therapy is effective in expediting the spontaneously favorable outcome of adhesive capsulitis and also allows to confirm the diagnosis. However, the subacromial bursa is almost consistently involved. Subacromial bursography with steroid injection can be useful in cases that fail to respond to conventional therapy.
