Clinical Significance of the Coraco-Humeral Distance in Patients with Subscapularis Tendon Tear: A Single-Center, Retrospective Study

We conducted this study to identify a correlation between the coraco-humeral distance (CHD) and the subscapularis tendon tears (SSCTs) in a single-institution setting. A total of 670 patients (n = 670) were included in the current study; they comprise 488 men (72.8%) and 182 (27.2%), whose mean age was 59.32 ± 12.58 years old. Depending on the presence of the SSCT and supraspinatus tendon tear (SST), they were divided into three groups: the control group (n = 179; the patients without SSCT and SST), the SSCT group (n = 133; those with SSCT only) and the SSCT+SST group (n = 358; those with both SSCT and SST). This is followed by comparison of the CHD between the three groups. The CHD was significantly greater in the control group as compared with the SSCT group and the SSCT+SST group (P < 0.05). In conclusion, our results indicate that there is a possible relationship between the CHD and SSCT. But further large-scale, multi-center studies are warranted to establish our results.
