New Bone Implant From Plant Cellulose

Bones are a very important part of the human body that allows as to be solid, strong and move. As important as bones are, humans tend to always break them and form catastrophic injuries. However, a great character of bones is the fact that they can regenerate. Yet, some extreme injuries cannot be saved.

A team of researchers from the University of British Columbia and McMaster University  were inspired by the issue and started a study on different one implants. They were looking for the most natural way that would lead to a healthy bone implant. The team was able to develop a bone implant which looks like foam that can be injected to bones for implants purposing.

The new substance is made from plant cellulose by treating nanocrystals making a stronger crystalline form lightweight sponge. This substance can easily be compressed and expanded to fill out cavities of different sizes.

The lead author of the study is PhD holder, Daniel Osorioa who is a student of Chemical Engineering at McMaster. He commented on their results saying, “Most bone graft or implants are made of hard, brittle ceramic that doesn’t always conform to the shape of the hole, and those gaps can lead to poor growth of the bone and implant failure. We created this cellulose nanocrystal aerogel as a more effective alternative to these synthetic materials. These findings show, for the first time in a lab setting, that a cellulose nanocrystal aerogel can support new bone growth.”
