Rotator cable and rotator interval: anatomy, biomechanics and clinical importance

[摘要] Rotator cuff problems are a common cause of shoulder pain and represent a significant expense and burden on the healthcare system. Despite the high rate of radiological prevalence of rotator cuff tears in elderly patients, many patients continue their lives with minimal symptoms. Several studies investigated asymptomatic shoulders in the general population and found that rotator cuff tears are relatively common, in the range of 6% to 34% in all age groups.1,2 A recent study by Yamamoto et al reported that nearly 20% of the general population have rotator cuff tears, with an increasing prevalence in elderly patients. They found that 50% of patients who are in their 80s have rotator cuff tears regardless of whether they are symptomatic or asymptomatic. Even patients without any shoulder symptoms accounted for 13.5% of the rotator cuff tears in the general population.3 Understanding the contribution of the rotator cable (RC) or rotator interval (RI) could be the answer to those.
