Geometry adaptation for stiffness reduction. (a) Initial model (full rectangular profile, Imax = 4915 mm4, Imin = 2507 mm4) in partial section. (b) Optimized prosthesis with U-profile (Imax = 2953 mm4, Imin = 2276 mm4) as basic geometry in partial section. (c) Prosthesis with U-hollow profile (Imax = 1387 mm4, Imin = 1043 mm4) in partial section
