Abstract:
The left clavicle of a healthy female was scanned by CT and serial sections were obtained. The CT images were fed into the Mimics and Ansys 10.0 software to construction a three-dimensional and finite element modeling of clavicle. Through meshing, assigning the material attribution, restricting the freedom and stimulating loading which effect to the vertical area of the acromion surface of clavicle, the result of stress and strain distribution and response of the model was obtained. Under the loading, the stress and strain mainly concentrated within the middle 1/3 part of the clavicle, and the stress on the superior surface was obviously highter than inferior surface. But the highest strain concentrated within the inferior surface of the middle 1/3 part of clavicle. The stress on superior surface of the middle 1/3 part of the clavicel was mainly tensile stress,or the inferior surface was compression stress. The stress and strain distribution didn't changed when the coracoclaviculare ligamenta was constructed. The result of finite element analysis of clavicle explains the reason why the middle 1/3 part of clavicle is prone to fracture, and the stress and strain distribution didn't changed when the coracoclaviculare ligamenta was constructed. Also, finite element analysis can be used to effectively understand the biomechanical characteristics of clavicle.
