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.ur 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?ll 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. |
