Expandable spinal implant system and method

摘要

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.

1. A method for treating a spine, the method comprising the steps of: providing a spinal implant comprising a first member including a wall that defines a first cavity and a second member extending between a first end comprising spikes and a second end that is disposed with the first member, the second member defining a longitudinal axis, the second member including a wall defining a second cavity; selecting at least one first bone graft for disposal in the second cavity; axially translating the second member 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 expanded within the first cavity and the first cavity includes a substantially void portion; and selecting at least one second bone graft having a selective configuration and dimension for disposal within the substantially void portion.
