Totally Biodegradable Implants for Bone Fixation and Ligament Repair

摘要

Synthetic biomaterials can be divided into metals, polymers, ceramics, and composites. Polymeric biomaterials and composites can be classified as biostable, partially biodegradable, or totally biodegradable. Biostable polymers are inert, cause minimal tissue response, and retain their properties for years. Because only a temporary supporting biomaterial is required in many clinical applications, totally or partially biodegradable polymeric materials are often better than biologically biostable materials.
