Abstract:
When the patients with senile or secondary osteoporosis are treated with screw fixation, the screws are likely to get loose or pulled out. Polymethylmethacrylate (PMMA) can enhance screw fixation strength to some extent in clinic, but PMMA has such disadvantages as irresorbability, polymeric heating effect and toxic reaction so that its clinical application is limited. Calcium phosphate cement, however, has drawn much attention because it gets rid of the shortcomings of PMMA. This article introduces recent progress made in research on fixation with calcium phosphate cement enhancing screw.
