Results of three-point bending test in control and HF-PEMF group at A) two and B) eight weeks after surgery. At two weeks postoperatively, the mechanical strength of femurs was higher in HF-PEMF compared to control group (35.1 N ± 5.6 vs. 21.83 N ± 4.2, p = 0.03), and the elastic deformation until fracture was smaller (0.7 ± 0.06 mm HF-PEMF vs. 1.03 ± 0.12 mm control, p < 0.01). At eight weeks postoperatively, the bending resistance of femurs increased in both groups, with no significant difference in mechanical strength (112.3 N ± 6.7 HF-PEMF vs. 100.5 N ± 7.2 control, p = 0.09) and elastic deformation (0.59 ± 0.06 mm HF-PEMF vs. 0.64 ± 0.08 mm control, p = 0.23) between two groups. *indicates statistically significant difference. HF-PEMF: High-frequency pulsed electromagnetic field; CG: Control group.
