Abstract

Implants including non-resorbable frameworks and resorbable components, as well as methods of use thereof are disclosed. The embodiments include different combinations of a non-resorbable framework (in some case structural and in other cases non-structural), and a resorbable component embedded within and/or around the framework (again, in some cases structural and in other cases non-structural). The disclosed implants provide an efficient means of providing structural support for the vertebral bodies post-implantation, as well as encouraging resorption of the implant and fusion of the associated vertebral bodies without negative side effects and/or failure, such as subsidence of the implant or cracking/fracturing of a portion of the implant when implanted.
