Abstract：To establish the three -dimensional finite element model of sciatic nerve injury,and then calculate the stress and dis-placement at the site of anastomosis with the three -dimensional finite element analysis software and provide the basic biomechanical experiments for the injury of sciatic nerve transplantation.The three -dimensional finite element model with 5mm,10mm,15mm, 20mm of sciatic nerve injury nerve autograft were established,we applied 10N tensile load on the force model,the displacement and stress values around each measuring point were calculated by using the finite element software (PROE5.0).The maximum stress of transplantation group with 5 mm is greater than that in transplantation group with 10 mm,15 mm and 20 mm under the same load simu-lation of sciatic nerve injury with autologous nerve.The maximum displacement of transplantation group with 20 mm is greater than that in the transplantation group with 15 mm,10 mm and 5 mm in the presence of 10 kf simulation with autologous nerve injury of sciatic nerve.It is feasible for sciatic injury model by numerical calculation using three -dimensional finite element method.
