本研究利用電腦斷層掃瞄影像資料建立腰椎運動單元之三維有限元素模型,配合生理解剖位置家上相關之椎間韌帶,藉較完整之腰椎模型來探討脊椎基本生物力學及各結構元件在承受不同形式外力負荷之貢獻度,以了解各部分之功能與對脊椎整體受力的影響。
目前研究結果顯示,脊椎在承受軸向扭轉負荷時,其運動範圍與勁度值較其它實驗小,但就整體而言大致呈現出相同的趨勢;而在其它種類之外力負荷中亦與實驗結果相似,顯示本研究目前所建構含韌帶之腰椎三維有限元素模型尚稱合理。
利用此模型探討椎間韌帶及面關節承受各種不同形式負荷,由分析結果可知椎間韌帶在脊椎承受前彎之外力負荷時,其所發揮的功能效果最明顯,而面關節則在脊椎承受軸向扭轉負荷時能提供脊椎整體穩定的功能,但在側向彎曲的負荷中兩者並無明顯之效果表現。本研究所使用之模型對於椎間盤的模擬上略有簡化,故藉由改變纖維環基質的材料強度以了解椎間盤材料變化對分析結果之敏感度,結果顯示椎間盤的材料性質確實是模擬過程中一個重要的因素。
本研究目前藉由分析結果對椎間韌帶及面關節在脊椎受到不同形式負荷下所扮演之功能與效果已有初步的認識,但所使用之模型仍有不足之處尚待加強,以期能對脊椎各部分結構元件做定量的評估,並提供臨床上脊椎損傷危險因子的評估。
This study presented a three-dimensional finite element model of a motion unit (with ligaments and facet joints) of the human lumbar spine, which could accurately simulate the complex geometry and non-homogeneous distribution of bone materials. The range of motion and the stiffness coefficient obtained from this model were compared with other obtained from experimental studies. Compatiable outcomes were shown in most loading modes except when the motion segment was subjected to torsion loading in which the simulated model had a less stiffer response. By using this model, the basic biomechanics of human lumbar spine and the contributions of each spinal component under different loading conditions were investigated. The results indicated that spinal ligaments played an important role in resisting flexion whereas facet joints were mainly responsible for preventing large axial rotation angle under torsion. Both of these two components had no significant contribution when the motion segment was subjected to lateral bending rotation. Due to the simplification of the intervertebral disc in this model, sensitivity analysis of the model was explored by modifying the material property of the annulus ground substance. The results concluded that disc properties was an important factor in simulating the intervertebral disc.
