Abstract

Flexible intervertebral spacers and associated methods are disclosed herein. In one embodiment, an intervertebral spacer includes a first support member configured to engage a superior vertebra of a spine, a second support member configured to engage an inferior vertebra of the spine, and a joint coupling the first support member to the second support member. The joint is adapted to limit the transverse relationship between the first and second support members while allowing relative movement between the first and second support members relative to each other during flexion, extension, bending, and rotation of the spine.
