Shoulder arthrography: A study for the correlation of anatomy and radiology

Shoulder arthrogram and dissection in cadaver were performed for clinical application. Puncture site for contrast injection was studied. The results were as follows: 1. Shoulder joints is located above the axillar and arthrography of shoulder is a simple, safe and easily interpreted. 2. The land mark for injection is a point 1.5 cm below the tip of coracoid process and very slightly medial to it. 3. There were contrast material leak from subscapular recess and distal end of the synovial sheath surrounding the long head of the biceps tendon in normal shoulder arthrogram. 4. Synoviad cavity margin show smoothness and no abnormal filling defect. 5. There were no communication between synovial cavity and subdeltoid bursa. 6. There were no specific anatomic variation in shoulder joint
