Biodegradable Implant Could Replace Donor Bones

Biodegradable Implant Could Replace Donor Bones
Nov-02-15
A new biodegradable implant made of cornstarch and volcanic ash could simplify the process of bone grafts by eliminating the need for bone donors.

Typically, bone grafts require removing bone from the patient’s body for use in the graft, or using donor bones, which are in short supply.

The new graft material was created by a team at Beaumont Hospital – Royal Oak in order to eliminate the need for a second surgery or donor bones. The biodegradable polymer has been reinforced with Montmorillonite clay nanoparticles for strength, and injected with carbon dioxide to create the a structure that is porous like natural bone while also remaining rigid. According to the team, the material will dissolve in the body after about 18 months,
