Table 2 Comparison of CHD, CI, HLT, CO, CGA, CHA, WST, and CD between normal and subcoracoid impingement syndrome group.

Normal groupSubcoracoid impingement syndrome groupZ valueP value
CHD (mm)7.7±1.54.7±1.2=−9.043
CI (mm)16.0±3.320.1±3.3=5.981
HLT (mm)5.5±1.06.6±1.4=4.787
CO (°)8.9±2.99.3±3.0=0.572=0.567
CGA (°)132.6±8.5126.8±9.6=−3.731
CHA (°)106.7±9.5110.2±10.5=2.205=0.027
WST (mm)5.4±1.36.4±1.8=3.623
CD (mm)8.9±2.310.5±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.
