摘要

An intervertebral spacer suitable for fixating a spine, including: a plastically-deformable surface, configured for increasing in diameter by said plastic deformation; and a plurality of protrusions formed of said surface, axially displaced along a long axis of said surface and adapted to stabilize said spacer against bone, when said spacer is radially expanded.
