28. GEOMETRY OF THE HUMERAL HEAD „ The humeral articular surface was spherical in the center; however, the peripheral radius was two millimeters less in the axial plane than in the coronal plane. Thus, the peripheral contour of the articular surface was elliptical (ratio, 0.92).“ Iannotti JP et al. JBJS Am 1992
