This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Every year there are approximately 9 million bone fractures in the United States, and 30% of these require an internal fixation device to help heal. Currently, the gold standard for fixation devices relies on the use of metals because of their high mechanical properties and bioinertness. However, metal implants often require a second surgery to remove them because they cause stress shielding and metal ion leaching. Current bioresorbable fixation devices on the market have poor mechanical properties and are limited to use in non-load-bearing applications (i.e. maxillofacial fractures). As such, there remains a gap in the fracture fixation devices on the market, where a bioresorbable, high-performance device could provide the mechanical stability of metal devices, while safely degrading in vivo. The present study focuses on the development of such a device by fabricating a composite material containing both long-fiber and particle reinforcement. Using novel processing techniques, a composite consisting of PLLA fibers, HA nanorods, and PCL matrix was fabricated and had a bending modulus and strength of 9.2 Gpa and 187 MPa, respectively. To increase the mechanical properties, statistically designed experiments (DOE) were employed to home in on an ideal material composition of the composite material, resulting in the use of SF fibers, HA nanowhiskers, and a PLA matrix. The final composite possessed a bending modulus and strength of 21.3 GPa and 531 MPa, respectively. This composite material was formed into a curved device and contained screw holes, resembling current metal fixation plates. These devices underwent an accelerated 8-week in vitro degradation study, in which the samples lost a total of 5 wt%. Additionally, cell proliferation studies showed cells increase proliferation through 7 days of culturing on the plates, and a cell viability assay revealed the samples have good in vitro biocompatibility after 14 days of culturing. Overall, the mechanical properties, degradation trend, and biocompatibility of the fabricated composites in this study show great promise for future use as a degradable load-bearing bone fixation device, in which in vivostudies will be needed to verify the efficacy of the composite material as a bone fixation device.

Download or read book Polymers in Medicine II written by E. Chiellini and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polymers and polymer based composites have gained increasingly larger applications in medicine and surgery. Presently, most biomaterials applications rely on industrial substances that were initially developed by industry for non-medical purposes. Moreover, polymers have been often used regardless of their peculiar characteristics which can be viceversa and very attractive for some specific applications. In the past years we have assisted to a significative and faster development of polymer science as well as of medicine and surgery. The assistance of computer aided apparatus, the use of always more advanced instruments, the larger interest of the academic and industrial world, bring continuously new contributions to the research on biomedical and parmaceutical use of polymers. The need of a forum where these specific researchs can be presented and discussed, and the success of the 1st Conference on Polymers in Medicine, held in Porto Cervo in 1982, have encouraged the Editors to plana periodical meeting, focused on polymers and composites, to be held every odd year. This book contains papers selected by an International Scientific Committee among those presented at the 2nd International Conference on Polymers in Medicine, Biomedical and Pharmaceutical Applications, held in Capri, Italy, 3-7 June, 1985. In addition to contributed papers, several Authors were invited to present the "state of the art" as well as their personal contibution on specific key arguments. The level of all contributions was high, the participation well qualified, and the meeting interesting and hopefully pleasant.
