应用断裂力学研究腓骨在下肢中的生物力学作用
The biomechanical role of the fibula in lower limbs:a fracture mechanics analysis
摘要
Abstract
Objective Fibular grafting is widely used in the treatment of various bone nonunions and defects because of its good therapeutic effects.However,the fibula plays important roles in the biome-chanics of the lower limbs.In this study,the biomechanical effects of the fibula in lower limbs were researched through mechanics analysis.Methods We randomly collected knee joint computed tomography(CT)scans from ten adults with normal bone mass(T≥-1),including six left knee and four right knees.None of the volunteers had bone pathologies.The CT scan images in DICOM format were imported into Mimics software,and the three-dimensional models of tibia and fibula were extracted in Mimics software.Each model was imported into 3-MATIC and LS-DYNA software for model processing and operation con-dition setting,and the changes of load and fracture time in the two models were calculated to evaluate the biomechanical role of the fibula in the lower limbs.Results The validity of the model was verified,and the fibular load condition was similar to those previously reported.In the model with fibular support,the fracture load of the tibia was 10.92±0.45 kN,the initial fracture time was 0.65±0.15 s,and the com-plete fracture time was 0.69±0.16 s.In the fibular defect model,the fracture load of the tibia was 9.60±0.37 kN(P<0.05),the initial fracture time was 0.49±0.11 s(P<0.05),and the complete fracture time was 0.54±0.12 s(P<0.05).Conclusion The fibula plays an essential biomechanical role in lower limb load-bearing and therefore is worthy of clinical attention.关键词
