Summary
Statistical analysis showed that the coracohumeral distance was not significantly narrowed in the group of subscapularis tear patients. These results show that narrowing of coracohumeral distanace is not a main cause of subscapularis tear.

Abstract
Introduction
It has been controversial for a long time whether subcoracoid impingement syndrome is the cause of subscapularis tear. So, this study aimed to determine and evaluate the relationship between the coracohumeral distance and subscapularis tendon tear.
Methods
We performed 164 arthroscopic shoulder surgical procedures between January 2007 and November 2013. 4 groups were classified in this study. Control group was 61 case, complete subscapularis tear group was 32 case, partial complete subscapularis tear group was 40 case, suprasupinatus tear group was 31 case. The coracohumeral distance was measured from the tip of the coracoid to the cortex of the proximal humerus on an axial cut of preoperative magnetic resonance imaging.
Results
The average coracohumeral distance in the complete subscapularis tear group was 8.95 ± 2.56 mm and the average coracohumeral distance in the partial subscapularis tear group was 8.66± 2.63 mm. The average coracohumeral distance in the supraspinatus tear group was 9.28±2.45 mm. The control group was 9.53 ± 2.65 mm. There was no statistically significant difference between the control group and patient group.
Conclusion
Statistical analysis showed that the coracohumeral distance was not significantly narrowed in the group of subscapularis tear patients. These results show that narrowing of coracohumeral distanace is not a main cause of subscapularis tear. So, further studies are required for etiology of subscapularis tear.
