Background: The location of rotator cuff tears (RCTs) is related to the shoulder pain in RCTs. Methods: A medical checkup was conducted for 402 residents of a mountain village. The subjects included 104 individuals with 200 shoulders in which RCTs were detected through ultrasonography (males; 80 shoulders, females; 120shoulders, mean age; 72.2 years old). The presence of pain in shoulders at the time of the checkup was confirmed using an interview form, and the locations of RCT as well as complication in the long head of the biceps (LHB) were diagnosed using an ultrasonography. The location of the tear was recorded under the three categories of the superior facet (SF) and the middle facet (MF) of the greater tubercle as well as the lesser tubercle (LT). Results: Complete RCTs showed a higher rate of pain in the shoulder than incomplete RCTs. In complete tears, RCTs which exceed the SF showed a higher rate of pain in the shoulder than RCTs which were limited to the SF. The presence or absence of LHB lesion was unrelated to the pain. Conclusion: The results of this study showed that rotator cuff tears started at the superior facet of the greater tubercle and more cases showed pain along with the widening of tears to the middle facet of the greater tubercle and lesser tubercle.
