Biomechanical testing of callus formation. Stiffness was not significantly enhanced in the estrogen (E)-treated group; changes in the alendronate (ALN)-treated group did not reach sham values. Yield load in the E group was significantly improved compared to the osteoporotic C (C) group, and superior to sham group. The ALN group was slightly enhanced compared to C. P values of <0.05 were considered to be significant (* P < 0.05 vs. sham, P < 0.05 vs. C,  P < 0.05 vs. E)
