ABSTRACT

Introduction: Fatty Infiltration is a degenerative condition in the muscle that affects its width and strength. After a rotator cuff tear repair in a muscle with fatty infiltration there is a 25% chance of failure rate. Fatty infiltration is a standard value to predict the outcomes after a rotator cuff repair. Objective: The aim of this study is to determine which measurements are directly related to fatty infiltration and it’s outcome after a rotator cuff repair. Material and methods: 133 shoulder Magnetic resonance images were assessed to determine the tear size, fatty infiltration of the supraspinatus, fatty infiltration of the infraspinatus/teres minor, acromio-humeral distance and Thomazeau index. A Pearson correlation index was calculated and a linear multiple regression analysis was performed to evaluate the variable influence of the fatty infiltration in the supraspinatus. Results: A strong positive correlation was found between the tear size and the fatty infiltration of the supraspinatus as well as the Thomazeau occupancy index. The infraspinatus/teres minor fatty infiltration has a moderate positive correlation with the supraspinatus fatty infiltration. acromiohumeral-distance has negative weak correlation between the fatty infiltration of the supraspinatus. Conclusions: Fatty infiltration of the infraspinatus/teres minor and acromio-humeral distance have non-statistically significance in relation with fatty infiltration. Tear size and the Thomazeau occupancy index had a p-value of statistical significance so they are related to the fatty infiltration of the supraspinatus, but muscular atrophy and fatty infiltration have different etiologies so they have a different influence on the outcome.
