摘要: 
人工髖關節在使用一段時間後,髖臼杯會受到人工股骨頭的影響,在X光片上可見到人工股骨頭往髖臼杯穿入的現象。這種股骨頭的移動量一直被視為內襯的磨耗深度,磨耗深度越深通常被認為產生的磨耗微粒也越多。這些微粒會使骨骼溶蝕,並且造成人工髖關節鬆動,普遍研究認為磨耗微粒的總體積應愈少愈好。
本研究計算兩種型式內襯之磨耗體積,依據內襯磨耗方向與磨耗深度的變化建立數學模型,並且使用向量積分計算內襯之磨耗體積。然後使用SolidWorks軟體建構三維模型與使用工具機製作實體模型驗證本研究之理論公式。研究結果顯示兩種型式內襯在正向磨耗時,磨耗體積等於股骨頭的移動量乘以股骨頭的截面積。不同尺寸的內襯在相同的磨耗深度與磨耗方向下,尺寸較大者會產生較大的磨耗體積。

The artificial hip joints in the use of a period of time, the acetabular cup appears penetration phenomenon. The relative movement between the femoral head and the acetabular cup may generate friction and material particles from wear are thus produced. These particles are formed as osteolysis and may cause artifical hip joint loosening, etc. The total volume of wear particles would be the less the better. Therefore, understanding of the wear volume/direction/depth becomes important.
In the study, calculation of two types of liner wear types based on the direction of liner wear and wear depth of the changes are studied. Mathematical models in terms of vector integral to calculate the liner wear volume is derived first. Then, using SolidWorks software to construct three-dimensional model is introduced. Finally, experiment with real subjects with entity models is preformed to verify formulas derived in the study. The results have shown that in the two types of the liner wears, the wear volume equivalent to the movement of the femoral head of the femoral head multiplied by the cross-sectional area in the front side significantly. The liner of different sizes in the same direction of the wear depth, the larger size of cups may have larger volume of wear.
