 note = {The purpose is to directly measure the glenoid depth and clarify its relationship with the stability ratio. We used 9 fresh-frozen cadaveric shoulders (mean age : 66 years, 5 males and 4 females). Naked glenohumeral joint was investigated. The shoulder was fixed to the custom designed measurement device with the glenoid surface horizontal to the floor and the humerus with 45° abduction and 35° external rotation. The stability ratio was 27.1 ± 6.5% (mean ± standard deviation) at 90° in the anterior, 26.2 ± 7.9% at 280° in the posterior (the minimum), 48.3 ± 10.4 at 10° in the superior, and 52.9 ± 12.5% at 180° in the inferior (the maximum) direction. The mean glenoid depth was 1.4 ± 0.3 mm at 90° and 270°, and 3.4 ± 0.9 and 3.3 ± 0.9 mm at 0° and 180°, respectively, showing that both the stability ratio and glenoid depth were minimal in the anterior 3 o’clock direction. The stability ratio increased as the glenoid depth increased, and the correlation coefficient was 0.92 ( p=0.01), showing a markedly strong positive correlation. The glenohumeral joint is most unstable in the anterior direction in terms of the bony stability.},
