Abstract

Purpose: To analyze 3D volume and pattern change of supraspinatus muscle following the size and location of supraspinatus tendon tear. Materials and Methods: A retrospective case-control study was performed assessing the volume and shape of muscle using Mimics® 17.0 (Materialise®, Louvain, Belgium) program for 3D reconstruction and assessing supraspinatus tendon tear size and location using 1.5T MRI in 40 patients. The correlation between the muscle atrophy and the tendon tear was statistically analyzed. Results: The results demonstrated a significant positive correlation between the muscle atrophy and the tendon tear.(p<0.05) And there was statistically significant difference between normal group and anterior & posteior rupture group in the shape of supraspinatus muscle according to location of tendon tear. Conclusion: From the result, we draw the conclusion that the size of supraspinatus tear was most important factor associated with the atrophy of the muscle. And we were able to prove that the location of the supraspinatus tendon tear dose not affect the atrophy pattern of supraspinatus muscle
