Abstract Summary
Despite there are many types of internal fixation devices for surgical treatment of acetabular fractures, reliable and accurate test method for assessing post-op biomechanical stability is still lacking. This makes more difficult for surgeons to accurately predict post-op stability of the device to meet various clinical demands. The purpose of this study is to develop a reliable testing apparatus that is capable of accurately assessing the 3-dimensional post-op stability of various internal fixation devices for both-column acetabular fractures.
