Injuries
-
Tennis players are susceptible to wrist cartilage injuries, which may not even present any symptoms at first. A van-based MRI system was designed with that in mind, as it can spot such injuries right at the tennis court, before they become serious.
-
Tendon injuries are painful and don’t always heal properly. Researchers at the Terasaki Institute have now shown that silk scaffolds loaded with stem cells can help tendons regenerate more effectively.
-
Researchers at MIT have developed a handheld robot that can help minimally trained responders to control severe internal bleeding in victims of traumatic injury, by helping them insert a needle and catheter into a major blood vessel.
-
In what is being described as a world-first, scientists in Israel have reportedly grown spinal cord implants utilizing tissue extracted from human volunteers. Those implants were then used to restore walking abilities to previously paralyzed mice.
-
After an injury, nerves struggle to regrow completely, leaving patients with reduced mobility and sensation. In tests on rats, researchers have now demonstrated a way to improve nerve repair using proteins from the support network around cells.
-
Complex bone fractures can be hard to treat, sometimes requiring the injured bone to be replaced with bone harvested from elsewhere in the body. Thanks to a new material, though, bone-building micro-robots may someday provide an alternative.
-
A new slug-inspired biomaterial improves tendon healing, with one sticky side and a low-friction outer surface that keeps it gliding against other tissues. Better yet, they can be loaded with slow-release drugs to reduce scarring and inflammation.
-
It’s hard to get medical adhesives to stick when blood is making everything wet. Now, MIT researchers have developed a new surgical glue that can halt bleeding within 30 seconds, inspired by the super-strong underwater adhesive used by barnacles.
-
When someone injures a nerve in a body part such as a finger, it's not uncommon for that part to end up with a permanently decreased sense of touch. A self-powered implantable sensor, however, could one day restore sensitivity to such injured areas.
-
Studies have already shown that electrical stimulation helps heal wounds, including broken bones. Scientists have now developed what could be a better way of delivering electricity to such bones, in the form of a biodegradable implant.
-
Presently, orthopedic surgeons use screwed-in metal plates to hold unstable broken bones together. There may soon be a less problematic, more customizable alternative, though, which incorporates a light-cured composite material.
-
Researchers have discovered a novel protein that can trigger the proliferation of muscle stem cells and promote healing, offering hope not only to those who have torn a muscle, but also the elderly and those suffering severe muscle wasting diseases.
