The authors analyzed 23 cases of shoulder arthrography performed at Busan National University Hospital andInje Medical College Paik Hospital for about 2.5 years from March 1981 to Sept. 1983, both clinically andradiologically. The results obtained were as follows; 1. Of the 23 cases, 20 cases (87.0%) were male and 3 cases(13.0%) were female, and the most prevalent age group was second decade. 2. Right shoulder arthrography wasperformed in 16 cases (69.6%), and left in 7 cases (30.4%). 3. The number of cases which had had certain historyof trauma was 13(56.5%), and remainder of 10 cases (43.5%) had no history of trauma. 4. Frequent symptoms andsigns were pain in shoulder region in 16 cases (69.6%) and limitation of motion in 14 cases (60.9%). 5. On plainfilm findings, 18 cases(78.3%) were normal, and 5 cases (21.7%) were abnormal. 6. On shoulder arthrographicfindings, 16 cases (69.6%) were normal, and 7 cases (30.4%) were abnormal, Those abnormal cases were consisted of2 case (8.7%) of adhesive capsulitis, 2 cases (8.7%) of chronic shoulder dislocation, 1 case(4.3%) of rotator cufftear, 1 case(4.3%) of loose bodies in joint cavity, and 1 case(4.3%) of rupture of biceps tendon sheath. 7. Amongroutine views of shoulder arthrography of normal cases, the external rotation view revealed axillary recess &biceps tendon more distinctly, and the internal rotaion view revealed subscapular bursa more clearly. In case ofdouble-contrast shoulder arthrography, the contour & thickness of the medial segment of the contrast -coatedhumeral articular cartilage were well demonstrated in erect viwes, with air-fluid levels in axillary recess,biceps tendon sheath & subscapular bursa. 8. The 2 cases of adhesive capsulitis revealed small joint space,obliteration of the axillary recess & subscapular bursa, and failure to fill the bicipital sheath. 9. The 2 casesof capsular deformities by chronic shoulder dislocation demonstrated loss of normal concavity of neck of thesubscapular bursa and redundant joint capsule. 10. The 1 case o typical rotator cuff tear showed abnormal fillingof the contrast medium into the subacromial-subdeltoid bursa. 11. Shoulder arthrography was relatively simple toperform, had no complication, and was regarded as very useful diagnostic method in evaluation of lesions in jointcavity.
