Successfully developed a foam that helps damaged bones recover quickly

This type of foam can be injected into areas of degenerative or cracked bones when performing surgical treatment.

We all know that the elderly will be prone to osteoporosis or broken legs, which will take at least a few weeks to recover completely. These things will most likely become a thing of the past when French scientists have successfully developed a special foam that is capable of restoring bone to bone degeneration symptoms such as osteoporosis, maybe even including trauma cracks. In addition, this foam can be injected directly into the bone without causing side effects.

In the past, doctors used microporous calcium phosphate phosphate (with pores of less than 2 nanometers in the molecular network) to treat osteoarthritis symptoms. Even so, it proved ineffective for bone samples that were too brittle or degraded for too long. Experts at the University of Nantes have converted calcium phosphate to macroporous (with pores of diameter over 50 nanometers) to support the recovery process for patients with osteoporosis more effectively in a shorter time.

Special foam is capable of restoring bone to the degenerative symptoms of bone.

Professor Pierre Weiss, the head of this project, said: "Our approach is quite simple when making good use of the mechanical properties of macroporous structures, this project will open for many pharmaceuticals. "Biology sells the method of activating structural molecules to treat troublesome diseases in old age like osteoporosis. Currently, we are still trying to study this issue further." This new drug is synthesized from yeast calcium phosphate and a special solvent for foaming, looking over looks very much like the common toothpaste.

This type of foam can be injected into areas of degenerative or cracked bones when performing surgical treatment. Scientists conducted experiments on rabbits fed under conditions of calcium deficiency and they regained bone quickly after a few days of testing, with no signs of toxicity or side effects. affect the body. Besides, the research team also experimented with fractures due to injury in breathing and the results were also very impressive when the cracks disappeared after more than 2 weeks of treatment.

In fact, calcium phosphate has been used by the medical industry as an anti-osteoporosis therapy since the 1920s, though patients often have to use them through the gastrointestinal tract, causing many risks to patients. kidney stones. Calcium phosphate is the main form of calcium in cow's milk and a small part of the bone is made up of hydroxyapatite, a mineral of calcium phosphate (called bone mineral).
