強大的外力直接衝擊肩膀時，鎖骨骨折是常見的外傷形式。雖然鎖骨骨折的致命率極低，但卻會造成上肢運動不便，嚴重影響日常生活及工作。
為了瞭解鎖骨的傷害機制及鎖骨的傷害情形，可以建立鎖骨的有限元素電腦模型進行分析與研究。但是鎖骨電腦模型的建立通常要透過高精度的電腦斷層掃瞄，得到斷面資料後再加以建模。此過程不但繁複且需要較高的時間以及金錢成本(高精度斷層掃瞄機的使用或維護費用)。本研究的目的在於，找出適當的鎖骨幾何參數，設計出一套將鎖骨複雜幾何參數化的建模方法，不需要透過電腦斷層掃瞄，也能建立出一根鎖骨電腦模型，具有和真實鎖骨相似的幾何特徵以及生物擬真性，可供有限元素分析使用。
本研究首先收集有關鎖骨幾何外型以及力學測試的相關資料，其中力學測試包括三點彎曲測試、鎖骨軸向靜力測試、動態撞擊測試。本研究根據鎖骨外型的資料，設計出鎖骨電腦模型的繪製方法，根據此方法繪製出均勻以及不均勻緻密骨厚度的鎖骨模型，除此之外也透過電腦斷層掃瞄建立真實鎖骨模型進行比較。之後整理各種大體測試的資料，繪製出生物驗證區間並用有限元素分析軟體做與大體測試相同的模擬測試，將模擬結果與生物驗證區間做比對，並用累積變異數比率CVR值來評估模型是否具有生物擬真性。本研究另透過強制振動試驗，獲得此鎖骨的振動頻率，作為真實鎖骨電腦模型擬真性驗證比對的參考。
本研究利用電腦模擬結果與大體資料交互比對，證實根據本研究設計的繪製方法所得到的鎖骨模型具有良好的生物擬真性。

When external forces direct impact on the shoulder, the clavicle is easy to be fractured. Although clavicle fracture is non-fatal, it will cause inconvenience to human arm movement and seriously affect the daily life and work.
In order to realize how clavicle be injured, we need a clavicle computer model which can be used in finite element analysis. Clavicle computer model is built normally via computed tomography. This process is not only complicated but also requires a higher cost time and money( The fees of using high-precision CT scanner).This study aims to design a method to build a clavicle computer model without going through a computer tomography. The clavicle model has similar geometric characteristics and biofidelity with real clavicle.
This study first collected data about clavicle geometry and cadaver test. Tests include three-point bending test, clavicle axial static testing and dynamic impact test. This study designed a method to build clavicle computer models. Then build an uniform and a nonuniform cortical thickness clavicle model. This study also built a clavicle model by computer tomography. Then we derived biometric corridor from a variety of cadaver tests. This study used finite element analysis software to do the same simulation tests with cadaver tests and compared the results. We used cumulative variance ratio value to realize the clavicle model has biofidelity or not. This study also obtained clavicle model’s and clavicle’s vibration frequency to validate clavicle model’s biofidelity.
This study proved the method to build a clavicle model is reliable and the models have biofidelity by many validation tests.
