Femoral segments may reconstruct tibial fractures, substituting fibular segments. The femoral segment size superior to the fibular segment and the necessity for femur fixation were determined. In 3-Point Bending, a 40% diaphyseal circumference femoral segment failed 225N higher than the fibula (p=0.047). Using uniaxial compression and FEA, the 40% segment osteotomy initiated yielding in the femur at 2443N (safety factor = 2447N). As a result, the 40% femoral segment is superior to the fibula but requires fixation of the femur.
