Magnesium-Containing Silicate Bioceramic Degradable Intramedullary Nail for Bone Fractures
Intramedullary nails (INs) have significant advantages in rigid fracture fixation. Due to the stress shielding effect and lack of biological activity, traditional metal INs often lead to delay union or nonunion fracture healing. Undegradable metals also need to be removed by a second surgery, which...

| description | Intramedullary nails (INs) have significant advantages in rigid fracture fixation. Due to the stress shielding effect and lack of biological activity, traditional metal INs often lead to delay union or nonunion fracture healing. Undegradable metals also need to be removed by a second surgery, which will impose a potential risk to the patient. Current degradable biomaterials with low strength cannot be used in INs. Manufacturing high-strength biodegradable INs (BINs) is still a challenge. Here, we reported a novel high strength bioactive magnesium-containing silicate (CSi-Mg) BIN. This BIN is manufactured by using casting, freeze drying, and sintering techniques and has extremely high bending strength and stable internal and external structures. The manufacturing parameters were systematically studied, such as the paste component, freeze-drying process, and sintering process. This manufacturing method can be applied to various sizes of BINs. The CSi-Mg BIN also has good bioactivity and biodegradation properties. This novel bioactive BIN is expected to replace the traditional metal INs and become a more effective way of treating fractures. |
