Spine support implant including inter vertebral insertable fluid ballastable insert and inter-vertebral web retaining harnesses
An implant support device associated with succeeding spinal vertebrae, including a harness exhibiting a plurality of legs, each extending from a rotatable bearing or suitable interconnecting support. Each of the legs terminates in an angled tang, this being engaged with a surface of a selected vertebrae. Additional features include undercut portions defined between the legs and arcuate/hemispherical mounting locations surrounding the bearing in individually rotatably permitting fashion. Inter-vertebral support cushions are also positioned between succeeding vertebrae, and can be incorporated with or provided separately from the web support harnesses.
1. An implant support device adapted for use with succeeding spinal vertebrae, said device comprising:
a flattened disk having a specified shape and size and which is adapted to being inserted between opposing surfaces of the succeeding vertebrae;
a first pair of legs extending from a three dimensional portion integrally formed along an edge of said disk, said first pair of legs each exhibiting multi-axial flexibility in order to conform in extending fashion over a contoured surface of a first of the succeeding vertebrae, said legs each terminating in a fastener adapted to engaging a location associated with the first vertebra;
a second pair of legs extending from said three dimensional portion in directions opposite said first pair of legs, said second pair of legs each exhibiting multi-axial flexibility in order to conform in extending fashion over a contoured surface of a second of the succeeding vertebrae, said second legs each terminating in a fastener adapted to engaging a location associated with the second vertebrae;
each of said first and second pairs of legs further having a spherical shaped end opposite said fastener end, said spherical shaped ends resistively fitting within a spherical shaped socket defined in communicating fashion with surface locations of said three dimensional portion,
said spherical ends facilitating motion between the vertebrae concurrent with cushioning the inner opposing surfaces of the first and second vertebrae.
2. The device as described in claim 1 , further comprising a finger projection for spacing said three dimensional portion from said edge of said disk.
3. The device as described in claim 1 , said fasteners further comprising integrally defined eyelet locations adapted to receive bone screws inserted through an open interior of each end configured eyelet such that enlarged heads of the screws abut against sides of said eyelets upon being adapted to anchoring within the vertebral bone locations.
4. The device as described in claim 1 , said fasteners further comprising integrally formed end supported and bone engaging screws for anchoring within vertebra bone locations.
5. The device as described in claim 1 , said disk further comprising an inter-vertebra cushion.
6. The device as described in claim 5 , further comprising said cushion being constructed of a flexible and fluid injectable plastic and, upon being pre-positioned between succeeding vertebra, being injected with an internally ballasting and curable/settable composition for establishing a degree of supported and incremental movement between the vertebrae.
7. The device as described in claim 1 , said three dimensional portion further comprising a spherical shape within which said spherical shaped individual pockets are formed.
