| Outline of Final Research Achievements |
For hip osteoarthritis, artificial bone is implanted to improve gait disturbance. This requires strong initial fixation of the implanted artificial bone. Also, in order to maintain the fracture in a normal position and aim for early recovery, it is necessary to induce new bone quickly. Create a 3D honeycomb shape similar to human cancellous bone,It was confirmed by in-vivo test using a dog body that wetting with body fluid was improved by applying a DLC coating on it and showed high bone conducting ability. 3D honeycomb artificial scaffolding material was revealed to be remodeled to a laminar bone with excellent strength characteristics in 12 weeks of implantation. We also performed gene analysis using the microarray method. As a result, it was confirmed that many intrigulin was expressed due to adhesion between bone and artifact.
