| dc.description.abstract | 全人工髖關節置換術後之髖臼元件方向，左右整個手術的成敗，電腦導引手術系統的進展，讓外科醫師有機會能精準的放置髖臼元件，更精準的手術，也需要更精準的方法來量測術後髖臼元件方向，而過去一些零星的研究報告，並無法提供我們完整量測、驗證的方法，本研究的目的，在從定義、量測標準、量測方法等相關問題作一個完整的探討。
本研究可分為四個研究，第一是量測標準的建立，是利用電腦軟體的方法，可以用人為調控的方式，調整各項要量測的参數，再合成X光片；第二項研究是我們所發明的一種新量尺，並使用第一項研究為量測標準做驗證；第三項研究是一個改進別人的量尺，也是使用第一項研究為量測標準做驗證；第四項研究是研究病人照X光片的問題，不同的姿勢會如何影響我們的量測，如何避免？能不能修正? 本論文之四大部分皆是原創性貢獻，總計獲得台灣專利一項，並有三篇論文被國際期刊接受，其中一篇已於2006年10月刊出，本論文提供量測髖臼元件方向相關問題的探討，希望能提供給相關的研究人員一個很好的工具，可以作相關臨床問題更深入的研究。 | zh_TW |
| dc.description.abstract | The success of total hip arthroplasty requires good orientation of acetabular component. The progress of computer navigation makes it possible to place the acetabular component with one to two degrees accuracy. However this accuracy needs precise tool to verify it. Previous reports do not provide total solution. We aim to do a thorough study from definitions, building gold standard, to developing measuring methods.
Our thesis consists of four studies. The first part is building gold standard by developing software. The users can adjust many parameters to verify their measuring methods. The second part is the development of a new protractor of measuring the orientation. We also verify it by the gold standard. The third part is the improvement of previously published protractor. We also verify our improvement by the gold standard. The final part is about the position problem while taking X-rays. Different positions do influence the orientation we measure. How to avoid and correct it? All four parts of this thesis are original. One of them is patented in Taiwan. Three of them are written in research articles and were accepted by international journals. One was published in October, 2006. Our thesis is a serial study about acetabular component orientation. We hope it can provide related researchers with good tools to further study of clinical significance. | en |
