Abstract
Devices for anchoring spinal implants in an intervertebral disc space are provided. Spinal implants are also provided that are resistant to lateral deformation. The implants may include a flexible peripheral supporting band disposed circumferentially about an elastic body. Methods for anchoring spinal implants and methods for reducing deformation of spinal implants are also provided.
Claims11
