肩インピンジメント症候群の肩峰下滑液包鏡視所見とＭＲＩ所見の比較検討

Abstract

It is difficult to objectively diagnose certain painful conditions of the shoulder such as impingement syndrome. Magnetic resonance imaging and arthroscopy of shoulder impingement syndrome excluding rotator cuff tear were evaluated in 40 patients. Patients who underwent magnetic resonance imaging before arthroscopy were reviewed after the operation. The high intensity area of T2* weighted images in subacromial bursa and rotator cuff tendon was checked as a sign of subacromial impingement.The high intensity area of T2* weighted images in the subacromial bursa and rotator cuff tendon was 80 and 17.5 per cent in the whole group. When the whole group was classified according to arthroscopic findings, the high intensity area of T2* weighted images in the subacromial bursa and rotator cuff tendon were 74 and 22 per cent in the group of significant subacromial frayed findings, 90 and 10 per cent in the group of rotator cuff tendon frayed findings without significant subacromial fraying, 100 and 0 per cent in the group of thickend coracoacromial ligament.
