RESORBABLE AND RADIOPAQUE DEVICE FOR BONE FIXATION

摘要

The invention relates to an osteosynthesis device that is resorbable and also radiopaque and that is made using materials that degrade gradually. The device comprises at least one plate and a set of screws made of resorbable material, wherein said plate is made of a first material consisting of a composite mixture comprising i) a resorbable polymer or copolymer compound and ii) a mineral charge composed of at least one resorbable ceramic, and said screws are made of a second material consisting of at least one resorbable polymer or copolymer compound, said first and second materials having different compositions, such that the respective Young's moduli are different. The device is totally resorbable and radiopaque, and it offers a high level of safety, ensuring stable and lasting fixation of the screws to the plate and in the bone throughout the period of time necessary for setting the bone.
