Porous metal for orthopedics implants

Fabrizio Matassi et al. Clin Cases Miner Bone Metab. 2013 May.

Abstract

Porous metal has been introduced to obtain biological fixation and improve longevity of orthopedic implants. The new generation of porous metal has intriguing characteristics that allows bone healing and high osteointegration of the metallic implants. This article gives an overview about biomaterials properties of the contemporary class of highly porous metals and about the clinical use in orthopaedic surgery.

Keywords: metallic scaffold; orthopedics implants; porous metals.
