Abstract

Systems, apparatuses and methods for preserving motion in an intervertebral disc. Modular disc implant segments can be constructed from a relatively rigid material with compressive spring lobes to act similar to an elastomer. The lobes may be configured to have a C-shaped outer wall and one or more spring arms, such as a leaf springs, to facilitate the modular disc implant segment's ability to compress, thereby enabling an entire intervertebral disc constructed from multiple modular disc implant segments to compress with the implant recipient's movement. The implant segments are sized to be inserted serially into a space defined by the annular fibrosus after removal of the nucleus pulposus with connections being made between adjacent segments in the space during the insertion process.
