Washington: Turns out, magnetic surgical cement heals spinal fractures and supplies the required drug supply.

Patients with spinal fractures, brought on by tumours or osteoporosis, often bear a process known as kyphoplasty, the place the fracture is crammed with surgical cement.

While kyphoplasty can stabilize the bone, most cancers sufferers are nonetheless usually left with spinal column tumours which might be very arduous to succeed in with standard chemotherapy, which has to cross the blood-brain barrier when delivered intravenously.

Researchers on the University of Illinois at Chicago discovered that by including magnetic particles to the surgical cement used to heal spinal fractures, they may information magnetic nanoparticles on to lesions close to the fractures.

Nanoparticles sure to varied medication have been used to focus on medication to particular areas or kinds of cells within the physique. Most generally, that is achieved by binding a minute quantity of drug to the nanoparticle, which is designed to additionally bind to a selected sort of cell, comparable to a most cancers cell.

Co-lead writer of the paper, Steven Denyer stated, “By modifying the kyphoplasty bone cement, we can both stabilize the spinal column and provide a targeted drug delivery system. This is a very promising technology as it has the potential to become a surgical option for patients with primary spinal column tumours or tumours that metastasize to the spinal column.”

Using a pig mannequin to check the magnetically-guided drug supply system, Denyer and colleagues had been efficiently in a position to steer magnetic nanoparticles to the magnetic cement within the animal’s spinal vertebrae.

Another co-lead writer of the paper, Abhiraj Bhimani stated, “Our study provides an in vivo proof-of-concept that this novel drug delivery system can help treat underlying causes of spinal fractures in addition to providing structural support.”

The full findings are current within the journal- PLOS ONE.



  1. I’m amazed, I must say. Seldom do I come across a blog that’s equally educative and interesting, and let me tell you, you’ve hit the nail on the head.
