Metal Materials Research Progress of Bone Injuries Repair

Repairing large bone defects caused by trauma or disease poses a significant clinical challenge. Metallic materials with good mechanical properties, biocompatibility and manufacturing processes can be used to repair bone defects. Materials utilized for mending bone defects encompass autogenous bone, allograft bone, metallic substances, bioceramics, polymers, and diverse composites. Biodegradable metallic materials such as iron, magnesium and zinc alloys are considered ideal for bone repair. Emerging metallic materials such as porous tantalum and bismuth alloys are of interest due to their affinity and versatility with bone. Although these materials have shown strong reconstructive capabilities in bone repair, there are still many challenges to overcome. However, there are still many practical difficulties associated with these metallic materials that need to be improved.
