Abstract
A spinal implant comprises an implant body extending between an anterior surface and a posterior surface. The implant body includes a first vertebral engaging surface and a second vertebral engaging surface. The implant body includes an outer surface that defines an oblique surface. A wall is connectable with the implant body and translatable relative to the oblique surface. Systems and methods are disclosed.
