The best recipe for 3D-printed replacement bones

Facial and head surgery can require sections of bone to be removed, and doctors often have to harvest material from elsewhere in the body to fill in the gaps. That's not always an ideal situation, and can lead to complications. New research coming out of the Johns Hopkins University could provide an alternative, creating custom-made, 3D-printed implants from a mixture of plastic and bone powder.Read More

Could the 3D-printed cast put plaster to pasture?

If you've ever had a cast on an arm or leg, then you'll know how uncomfortable, awkward and inconvenient they can be. That's why the NovaCast was created, by Mexican startup Mediprint. It's a 3D-printed cast which is custom-made for each patient as needed, and that addresses many of the limitations of traditional plaster casts.Read More

Preconditioned cells may help heal major bone fractures

While the body can fix small bone breaks with relative ease, more significant injuries such as large bone defects or fractures are a little more tricky, often requiring some extra help to mend. Now, scientists from KU Leuven in Germany are improving the effectiveness of treatments to deal with those more serious situations, preconditioning cells before implantation, allowing them to better deal with the often inhospitable environments at wound sites.Read More

Biodegradable implant could simplify bone replacement surgery

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.Read More

Wearable airbag designed to protect seniors when they fall

For anyone who uses a car, collisions are an ever-present danger – that's why vehicles are equipped with safety features such as airbags. For senior citizens, however, simply falling down can also result in life-changing injuries. With that in mind, Pennsylvania-based company ActiveProtective is developing a wearable airbag that deploys in the event of a fall, to protect seniors' hip bones. Read More

Magnetically-directed nanoparticles could help heal broken bones

When a bone is severely broken in the human body, or a bone-fused prosthesis is implanted, a bone graft is also often required to ensure a solid mechanical repair. However, a graft that removes bone from another area of the body can be a painful and invasive procedure, and the mechanical stimulation required for continued bone regeneration in post-operative therapy becomes problematic if a patient is severely immobilized. To address these problems, researchers have discovered that coating magnetic nanoparticles with proteins and then directing them magnetically to the site of the injury can help stimulate stem cells to regenerate bone.Read More

MIT scientists use polymer scaffold to stimulate bone growth

A team of chemical engineers from MIT has developed a new method of stimulating bone growth, by utilizing the same chemical processes that occur naturally in the human body following an injury such as a broken or fractured bone. The technique involves the insertion of a porous scaffold coated with growth factors that prompt the body's own cells to naturally mend the damaged or deformed bone.Read More
