Combining cornstarch with volcanic ash clay to create a plastic for bone grafts could make the surgical process of bone replacement much simpler in the future. Researchers say the material could replace the need to remove bone from another part of a patient's body, or to use donor cadaver bones that are limited in supply.
Complex nerve injuries are a challenging problem for the medical fraternity, as their reattachment and regrowth is a fraught and delicate process that is very rarely successful. Overcoming these difficulties, however, would mean that a cure for debilitating conditions like paraplegia, quadriplegia and other forms of paralysis may one day be found. In this vein, US researchers have created the first-ever 3D printed guide specifically designed to assist in the regrowth of the sensory and motor functions of complex nerves.
