| dc.description.abstract | 一般來說，人們隨著年齡的增長在椎間盤裡的髓核就會開始退化，造成椎間盤的厚度減少，進而造成黃韌帶及小面關節的肥大，以致於引發壓迫到神經，造成椎間盤退化性疾病(DDD: Degenerative Disc Disease)，而解決此種症狀的方法手術中使用動態固定器與靜態固定器，恢復塌陷椎間盤之原有高度，進而解決椎間盤退化的問題。 本研究為利用SolidWorks建立腰椎模型與靜態內固定器，先將腰椎模型加入肌肉群力，使分析更接近真實狀態，透過COSMOSWORKS有限元素軟體分析三種不同腰椎模型：正常腰椎、腰椎植入鈦合金靜固定器、腰椎植入316L不鏽鋼靜固定器定器三種模型來進行有限元素分析。主要模擬分析正常腰椎模型椎間盤高度與角度變化、髓核應力、椎弓足應力，所產生的應力分佈情形，將正常腰椎植入兩種靜態固定器透過有限元素分析，了解靜態內固定器對腰椎周圍醫學組織之生物力學影響。

| dc.description.abstract | Generally,the marrow of intervertebral disk was begun degenerating by increasing age of human.This degenerating reduces the thickness of an intervertebral disk & hypertrophy of ligament & facet joint,so that it gives rise to stress the nerve and resulted in DDD. The solution for this kind of case is that we use the static fixation to recover the initial thickness of intervertebral disk by a surgical operation, so that we can solve the problem of degeneration of intervertebral disk. This research utilizes the ＂SolidWork＂ to construct the model of lumbar vertebra & static fixation.Firstly, we put the muscle force into the model of lumbar vertebra to make this analysis close to the status of reality. It analyzes three different kinds of model of lumbar vertebra via cosmosworks’’s software of limited element : the normal lumbar vertebra、the lumbar vertebra with implanting an alloy of titanium,the lumbar vertebra with implanting 316L Stainless Steel fixation,there are three kinds of model to proceed the analysis of limited element. The majorly simulation is to analyze the height,change of angle,stress of nucleus pulposus,stress of pedicle of the model of lumbar vertebra and the status of stress distribution.
