Implantable bio-patch grows bone where it's needed

By - November 12, 2013
Help could be on the way for people who don't have enough bone to support dental implants, who are missing bone due to a birth defect, or who have suffered bone-damaging injuries. Scientists at the University of Iowa have created an implantable collagen patch seeded with particles containing synthetic DNA, that instructs the patient's own cells to produce the protein that leads to bone growth.

"Microscopic shag carpet" may help bones bond with implants

By - July 31, 2013
Like a lot of things, bone cells grow and reproduce quicker on textured surfaces than on smooth ones. With that in mind, a team of scientists from Ohio State University are developing a new coating that could allow implants such as artificial hips to bond with bones faster. That coating is described as “a microscopic shag carpet made of tiny metal oxide wires.” Read More

3D-printed Cortex concept scratches the itch of healing broken bones

By - July 2, 2013 6 Pictures
The only thing worse than breaking a bone is waiting for it to heal. During the healing process itself, wearing a fiberglass and plaster cast can be a stinky, itchy endeavor that is uncomfortable and inconvenient; all for an injury that is completely internal. Enter Jake Evill's Cortex concept. Beyond having an awesome last name, Jake Evill, a media design graduate of the Victoria University of Wellington in New Zealand, has managed to modernize the ancient concept of a splint using 3D printing technology.

Plastic used to replace and regrow bone

By - February 8, 2013
Over the past several years, a number of research institutes have been exploring the use of implants made from material with a scaffolding-like structure, as a means of regrowing bone at severe injury sites. Both MIT and Tufts University, for instance, have been working on collagen-based materials. Now, England’s University of Southampton has announced the development of a new type of bone-growing substance, made from plastic. Read More

German scientists creating a high-tech artificial hip

By - May 7, 2012
While modern artificial hips are made of a number of high-tech materials, metal is still often the material of choice for younger, more active patients. This is due mainly to the fact that it’s so robust. Unfortunately, however, difficulties can arise in the metal ball-and-socket interface – where the artificial head of the femur meets the artificial socket of the pelvis – if things aren't perfectly aligned. In particular, the metal surfaces can wear against one another, decreasing the longevity of the implant and potentially causing health problems in the patient. Now, researchers from Germany’s Fraunhofer Institute for Manufacturing Engineering and Automation are developing a new type of heavy-duty artificial hip, that contains no metal at all. Read More

Students create automated bone-lengthening device

By - April 25, 2012 4 Pictures
Whether it's from injury, infection or malfunctioning genes, millions of children suffer from bone deformities at any given time. To help remedy the situation, doctors often resort to the painful practice of breaking the target bone and then repeatedly moving the ends apart as they attempt to grow together – a procedure known as distraction osteogenesis (DO), that has its share of risks and problems. Now, a team of undergrad students from Rice University (RU) in Texas has come up with a device they hope will make the lengthy process of bone-stretching both easier and safer for the young patients who have to endure it.

Nanocoating designed to keep hip implants where they belong

By - April 24, 2012
Probably the simplest way to describe an artificial hip would be to say that it’s a ball attached to a stem. The stem is often fastened to the open end of the femur using a glass-like polymer known as bone cement, while the ball takes the place of the original hip bone’s ball joint, rotating within a corresponding implant in the socket of the pelvis. Although problems can occur at that ball-and-socket interface, they can also result when the bone cement cracks, causing the stem to detach from the femur. Scientists at MIT, however, have developed a new type of nanoscale film coating, designed to keep that from happening. Read More

Forensic software determines race and gender based on skull measurements

For some time now – whether by using computers or clay – forensic scientists have been able to make three-dimensional reconstructions of the faces of the deceased, based on the contours of their skulls. More recently, however, software has been developed that can determine the sex and precise ancestral background of a person no longer with us, via a set of skull measurements. Read More
