Table 2 Comparison of CHD, CI, HLT, CO, CGA, CHA, WST, and CD between normal and subcoracoid impingement syndrome group.
| Normal group | Subcoracoid impingement syndrome group | Z value | P value | |
|---|---|---|---|---|
| CHD (mm) | 7.7±1.5 | 4.7±1.2 | =−9.043 | <0.001 |
| CI (mm) | 16.0±3.3 | 20.1±3.3 | =5.981 | <0.001 |
| HLT (mm) | 5.5±1.0 | 6.6±1.4 | =4.787 | <0.001 |
| CO (°) | 8.9±2.9 | 9.3±3.0 | =0.572 | =0.567 |
| CGA (°) | 132.6±8.5 | 126.8±9.6 | =−3.731 | <0.001 |
| CHA (°) | 106.7±9.5 | 110.2±10.5 | =2.205 | =0.027 |
| WST (mm) | 5.4±1.3 | 6.4±1.8 | =3.623 | <0.001 |
| CD (mm) | 8.9±2.3 | 10.5±3.8 | =2.233 | =0.026 |
| The results are expressed as mean±standard deviation (SD); CHD – coracoid-humeral distance; CI – coracoid index; HLT – height of lesser tuberosity; CO – coracoid obliquity; CGA – coracoglenoid angle; CHA – coracohumeral angle; WST – width of the subscapular tendon; CD – contact distance between subscapular tendon and coracoid process. | ||||
