肱骨三维模型的构建及其生物力学意义
Construction of humeral three-dimensional model and its biomechanical significance
摘要
Abstract
BACKGROUND: Various therapies can be used to treat humeral fracture,but serious complications like bone disunion, etc. Are often left over. New biomechanical analytical methods are tried to be applied to provide new approaches for the functional prognosis in humeral fracture and bone disunion.OBJECTIVE: To construct humeral three-dimension model to explore its correlated biomechanical significance.DESIGN: To construct humeral three-dimension finite element model. SETTING: Department of orthopedics of a military medical university-affiliated hospital and institute for biological science and bioengineering of a university.PARTICIPANTS: The study was conducted in Shanghai Changhai Hospital and the Laboratory of Biological Science of Shanghai Tongji University. One piece of typical adult wet humerus sample was selected.INTERVENTIONS: Cross section image of each humeral layer was obtained from the selected wet humerus sample by CT scanning, and humeral three-dimensional model was constructed by large finite element analytic software ANSYS5.6.MAIN OUTCOME MEASURES: ① Biomechanical features of the constructed humeral three-dimension mode; ② Differences from clinical reality and key similarities.RESULTS: The constructed humeral three-dimensional model vividly reflected the true humeral anatomic morphology and biomechanical behavior. Its precision was judged by the comparison with CT image.CONCLUSION: The construction of humeral three-dimension finite element model provides a precise model for the researches of normal humeral mechanical behavior and the basic mechanics of internal fixation after fracture.关键词
