Better Hip Replacement Tricks Bone by Being Porous

Nov-12-16 A new implant from researchers at McGill University mimics natural bone to extend the life of hip replacements.

The implant, called a femoral stem, is meant to mimic the changes in density in the body’s actual femur. To create the gradated structure, the team designed the implant with “hollowed-out tetrahedral,” resulting in varying densities within the material. Since the material mimics the structure of the surrounding femur, the natural bone continues to thrive, reducing the chances of rejection.

The implant is also lighter and able to absorb stress more efficiently, causing less strain on the body, and less pain.
