The effect of porosity gradients on compressive strength of hydroxyapatite scaffolds

Nowadays, the main treatment for children with bone cancer is limb salvage. To prevent this, a new design for an expandable endoprosthesis for the knee has been developed. This proposal contained a bioresorbable ceramic component, made out of hydroxyapatite (HA), with a porosity gradient which will be subjected to a compressive load. In order...
