Abstract—This study aimed to evaluate the external fixation for femoral bone fracture by possibly using the 10-hole locking compression plates (LCPs). A comparison of LCPs, including 10-hole board LCP and 10-hole narrow LCP, was analyzed under femoral bone cutting at a 1 mm increment. The maximum load on 800 N, then, the structure was analyzed for dual LCP by making the implant model on the side lateral-anterior. The result of the study demonstrated that both board LCP and narrow LCP had the maximum stiffness above the maximum stress of the structure and greater than the ultimate tensile stress of 304-stainless steel. Recheck a board LCP model that was unable by torsion load on 12 Nm. Thus, increasing a board LCP on the side anterior of the femur, or dual LCP, was appropriated to treat femoral bone fracture as the external fixation because dual LCP can be the overall load.
