Abstract

A spinal implant comprises a first member including a wall that defines a first cavity and a second member including a wall defining a second cavity. At least one first expandable bone graft is disposable within the second cavity. The second member is axially translatable relative to the first member between a first configuration and a second, expanded configuration such that at least a portion of the at least one first graft is disposed within the first cavity and the first cavity includes a substantially void portion. At least one second bone graft has a selective configuration and dimension for disposal within the substantially void portion. Systems and methods are disclosed.
