Dog and sheep bones help injured pigeons fly again

Sheep and dog bones can be whittled into orthopedic pins that stabilize pigeons' fractured wings, helping the fractures to heal properly without follow-up surgery. Researchers describe the treatment, which is cheaper and ...

New hydrogels show promise in treating bone defects

Bioengineers and dentists from the UCLA School of Dentistry have developed a new hydrogel that is more porous and effective in promoting tissue repair and regeneration compared to hydrogels that are currently available. Once ...

Messenger cells bring good news for bone healing, study finds

How do bones heal, and how could they heal better? The answer to these questions may lie in a newly discovered population of "messenger" cells, according to a recent USC Stem Cell study published in the journal eLife.

Fewer surgeries with degradable implants

Until now, in cases of bone fracture, doctors have used implants made of steel and titanium, which have to be removed after healing. To spare patients burdensome inter- ventions, researchers are working on a bone substitute ...

Better tissue healing with disappearing hydrogels

When stem cells are used to regenerate bone tissue, many wind up migrating away from the repair site, which disrupts the healing process. But a technique employed by a University of Rochester research team keeps the stem ...

Bone grafting improvements with the help of sea coral

Sea coral could soon be used more extensively in bone grafting procedures thanks to new research that has refined the material's properties and made it more compatible with natural bone.

Math predicts size of clot-forming cells

UC Davis mathematicians have helped biologists figure out why platelets, the cells that form blood clots, are the size and shape that they are. Because platelets are important both for healing wounds and in strokes and other ...

Models suggest treatments for fractures that won't heal

New models, reinforced by in vivo experimentation, show why 5-10% of bone fractures don't heal properly, and how these cases may be treated to restart the healing process. Results of the model, published September 2 in the ...

Nanotubes that Heal: Engineering Better Orthopedic Implants

(PhysOrg.com) -- Titanium and its alloys have a leg up on all other materials used to make the orthopedic implants used by surgeons to repair damaged bones and joints. They are light, super-strong, and virtually inert inside ...
