Abstract

A spinal intervertebral support implant, for fusion or for dynamic stabilization purposes. A rod, preferably in the form of a screw, is inserted obliquely from the pedicle of an inferior vertebra into the body of a neighboring superior vertebra, through the disc space. The rod can be anchored into the body of the superior vertebra by means of a force fit or a screw thread. A pile of elements is disposed on the rod in the disc space like a pile of washers, so that the compression load between vertebrae is carried partly by these elements. These elements can be inserted through the bore through which the rod was inserted in a tightly folded configuration, and deployed into their washer-like form only when in position in the intervertebral space, such that there is no need for any additional incisions.

First claim

We claim:

1. An intervertebral support system comprising:
a rod having a first end section adapted for post-operative affixing in the body of a first vertebra of a subject, the rod being dimensioned to be inserted through a bore in a pedicle of a second vertebra of said subject, adjacent to said first vertebra;
a plurality of separate solid elements having lateral dimensions substantially larger than that of said bore disposed on said rod in a stack directed between the end face…
