Injuries

​When someone is missing facial bone due to injury or illness, the current treatment involves transplanting a piece of bone extracted from the leg, leaving a deficit there. Now, however, scientists have succeeded in growing extra bone within sheep's bodies, that's preformed to the shape required.

A study has affirmed the anesthetic xenon can help prevent long-term damage associated with traumatic brain injury (TBI). The research demonstrated in mice that if xenon is administered within a few hours of a TBI it can prevent brain tissue damage that would result in long-term cognitive problems.

​For some time now, we've been hearing about implantable scaffolding-like material that helps heal injuries to bones. Scientists have now developed a new type of that material, aimed specifically at difficult-to-treat osteochondral injuries.

Scientists have come up with a molecule that can spur different cells into action throughout different stages of wound healing, enabling a new kind of dynamic technology that could be channeled into materials that respond to the task at hand.

​Even a single fall can seriously impact a senior, so it's best if such accidents can be kept from occurring in the first place. A new wrist-worn sensor, developed by scientists at Germany's Karlsruhe Institute of Technology (KIT), has been designed for just such a purpose.

​Currently, if someone has a damaged cornea (the surface of the eye), it's covered with a "bandage" made from the amniotic membrane of human placentas. While this helps repair the eye, an Australian scientist is developing what he believes may be a better alternative – a wound-healing contact lens.

​It's no secret that jobs which involve a lot of bending, twisting or reaching can cause debilitating injuries. Sometimes, though, it's hard to remember to do those things the right way. The wearable Kinetic Reflex is designed to help workers in that regard, by alerting them to unsafe postures.

A new study describes progress in a groundbreaking technique that is helping paraplegic patients walk again. The experimental process, involving electrically stimulating the spinal cord, is proving increasingly promising as research works to improve the design of the treatment.

Georgia Tech researchers have developed a hydrogel that holds muscle stem cells, and by injecting this near the site of a muscle injury they can get to work repairing it. The team says the technique could be effective at treating injuries in the elderly and people with muscular dystrophy.

Researchers at the University of Minnesota have designed a silicone device, covered in 3D-printed neuronal stem cells, that can be implanted into a spinal injury. There it grows new connections between remaining nerves to let patients regain some motor control.

A team of researchers has successfully regenerated spinal tissue in rat models. Using a common antibiotic as the on/off switch, the therapy breaks down scar tissue and allows new nerve cells to grow, resulting in rats with spinal injuries relearning complex hand movements.

​Not only are large scars often unsightly, but the stiff scar tissue can also limit a person's range of motion, causing discomfort. And although there are procedures that minimize scarring, it's not always apparent if such measures need to be taken. New nanoparticles could help doctors decide.
