腱板大断裂に対しLeeds-Keio人工靱帯と大腿筋膜による複合組織移植を行った症例の術後成績と術後Motion MRI

抄録

We have transplanted a Leeds-Keio artificial ligament covered with patients' own iliotibial band from greater tubercle of the humerus to belly of supraspinatous muscle where blood supply seems sufficient. We investigated and evaluated the postoperative transplanted structures by motion MRI. We operated on 5examples of 5 shoulders, during the 40 rotator cuff reconstructions of 42 shoulders from April,2000 to March,2004. We evaluated the transplanted tissue by using 0.3T constant conduction MRI. Also we observed the movement of the transplanted tissue by motion MRI. Post operative evaluations were made according to the JOA score. The JOA score had increased from 9 to 28 in the pain score, from 8.8 to 18 in the functional score, from 49.5 to 82.2 in the total score, and each scale had improved statistically significantly(P<0.05). This postoperative T1-weighted MRI study showed transplanted tissue low intensity, which looked like a rotator cuff. Also it attended on the occasion of shoulder abduction. We were satisfied with our results of operative treatment for a rotator cuff tear.
