摘要: 
在一般的情況下使用一段時間之後,股骨頭和髖臼杯之間的間隙會逐漸增大,在步態分析上可能會產生一些影響。
本研究主要應用有限元分析與赫茲接觸理論,並討論人工髖關節之間的股柄與髖臼杯受重力負荷之下可能產生的破壞情形。並且在股骨柄與骨水泥和股骨柄與皮質骨相互接觸的地方加入接觸元素。包括股骨柄與髖臼杯分離後所產生之重力負荷分析以及應力分析,並且比較股骨柄與骨水泥和皮質骨,有接觸元素與無接觸元素兩者的關係。
結果顯示,股骨柄與髖臼杯之間的分離量愈大,所產生之衝擊負荷也就愈大,它們之間呈現非線性的關係。當股骨頭愈大與髖臼杯所產生的衝擊負荷也就愈小。
在股骨柄有加入接觸元素的接觸面上所產生的應力值不同於一般有限元素的計算結果其結果更為明顯。

In general, having used for some period, the gap between femoral head and the acetabular cup is increased and the gait analysis may loss its significance.
This research mainly focuses on the application of the finite element analysis with Hertz contact theorem and discusses the destruction situation of artificial hip joint between stem and acetabular cup under the gravity loads. The stem with bone cement and cortical bone contact one another and contact elements are applied. It includes the derivation of gravity loads due to separation of stem and acetabular cup and comparison of mechanical behaviors in the stem, the bone cement and the cortical shell with and without contact elements.
The results show that, the larger the separation between stem and acetabular cup is, the greater the impact load is and the nonlinear relation between them is present obviously. The larger the femoral head and acetabular cup are, the smaller the impact loads are.
The stresses generated on the contact surface of the stem are much different from those calculated from the general finite element results and more physically significant.
