Purpose: Although the morphological relationship of the scapula and the humeral head has been claimed to be related to
shoulder pathologies, few studies examined the relationship between subscapularis (Ssc) tears and lesser tuberosity (LT)—
humeral head (HH) and between Ssc tears and HH—glenoid. This study aims to evaluate the relationship of LT with HH
and glenoid in patients with Ssc tears and anterior shoulder instability (ASI). We hypothesized that the glenoid, HH, and
their combined relationship with LT may impact Ssc tears and ASI.
Material and methods: The study included 34 patients with ASI, 28 patients with isolated Ssc tears, and 40 patients as the
control group. The radius of HH (Hr), the distance between the center of HH and LT (LTr), and the glenoid radius (Gr) were
measured in shoulder magnetic resonance (MR) images. The LTr to Hr (LTr/Hr) ratio was defned as the lesser tuberosity humeral head index (LTHHI), whereas the LTr to Gr (LTr/Gr) ratio was defned as the lesser tuberosity-glenoid index (LTGI).
The three groups were compared regarding LTHHI, LTGI, LTr, Hr, and Gr.
Results: There was a signifcant diference between each group concerning LTGI (p<0.001). LTGI values below 1.99 showed
93.1% sensitivity and 93.3% specifcity for Ssc tears, while values above 2.24 showed 86.7% sensitivity and 86.2% specifc ity for ASI. Also, there was a signifcant diference when the groups were compared for LTHHI (p<0.001). This rate was
lowest for Ssc tears, and LTHHI values below 1.17 showed 82.8% sensitivity and 80.1% specifcity.
Conclusion: LTGI may be a new predictive factor showing 93.1% sensitivity and 93.3% specifcity for Ssc tears and 86.7%
sensitivity and 86.2% specifcity for ASI. In addition, LTHHI may be a new predictive factor showing 82.8% sensitivity and
80.1% specifcity for Ssc tears.
Level of evidence: III retrospective comparative study.
