近年來利用有限元素法分析脊椎生物力學相關研究層出不窮，主要是因為運算功能強大的計算機紛紛問世，也使得原本分析需要的時間減少非常多，對於生物力學發展有明顯突破。此研究內容在於建立脊椎有限元素模型，結合簡單的生物力學探討研究。
本研究針對教學用脊椎模型，與成大醫院骨科以及醫學工程所合作，使用成大醫院斷層掃描儀器結合醫學影像軟體3D-DOCTOR，處理輸出與實體模型近似之表面模型，使用MSC.PATRAN軟體建立有限元素網格，前處理則包括手動加入椎間盤、邊界條件等步驟，Solver使用ABAQUS進行有限元素分析。
基本生物力學分析，包含了脊椎骨材料性質、邊界條件、非線性韌帶以及小面關節的接觸性質，針對幾種運動模式正常站立、彎曲、伸展、側彎、扭轉分析脊椎在這五種狀態下之行為，並比較頸椎、腰椎、胸椎、薦椎在這五種運動進行時之趨勢。

Because of the modern technology computers are devised, many studies of biomechanical are improved by finite element method. The computers will save us a lot of time to get the analytic results. In this dissertation we create the vertebrate model by finite element method and discuss all FSU by simple biomechanical.
First we use CT to scan all vertebrate, then improve the DICOM.file to 3D-Doctor, finally improve the STL.file to MSC.PATRAN. After all the processes we set materials, properties, boundary conditions.
This study uses the notable finite element method to simulate the human spine from cervical to lumbar (C2~L5). This finite element model adopts the distinct semiautomatic modeling method to build the truly accurate geometrical human spine from CT scan (not including the ribs and cervical) and contains the facets contact interactions and the programmable nonlinear ligaments. The numerical results are confirmed by the validation and convergence test. In the conclusion, the feasibility of analyzing the entire spine could be verified by this study.
