Subacromial bursography.

Subacromial bursography was performed on 250 patients with following results. Bursographically, the subacromial bursa was found to have three intercommunicating portions with various frequency; subacromial, subdeltoid and subcoracoid. In complete rotator cuff ruptures, the contrast medium leaked into the shoulder joint. In 'frozen shoulder' the subacromial bursa is reduced in size according to the degree of contracture. The intrabursal injections of steroid hormone and Lidocaine proved to have definite therapeutic and pain alleviating effects.
