9 . The method of claim 1 wherein the elastic material is an elastomer or a rubber.
10 . The method of claim 1 wherein the posterior motion preservation system comprises a semi-rigid rod or a flexible rod.
11 . The method of claim 1 wherein the posterior motion preservation system comprises an inelastic material.
12 . The method of claim 1 wherein the posterior motion preservation system comprises an elastic portion.
13 . A method of treating a spinal condition comprising:
attaching an anterior system between a pair of vertebrae to reinforce or stabilize an anterior motion segment; and
augmenting a vertebral body of at least one of the pair of vertebrae with at least one of a vertebral body augmentation material or an endplate augmentation material.
14 . The method of claim 13 wherein the vertebral body augmentation material is a bone cement.
15 . The method of claim 13 further comprising:
creating a void in the vertebral body.
16 . The method of claim 15 wherein the void is created with an inflatable device.
17 . The method of claim 15 wherein the vertebral augmentation material is from a group consisting of polymethylmethacrylate (PMMA), calcium phosphate, hyrdroxyapatite- tricalcium phosphate (HA-TCP) compounds, bioactive glasses, polymerizable matrix comprises a bisphenol-A dimethacrylate, thermoset cortical bone void filler, demineralized bone matrix, collagen, gelatin, polysaccharide, hyaluronic acid, keratin, albumin, fibrin, and combinations thereof.
18 . The method of claim 13 wherein the endplate augmentation material is from a group consisting of polymethylmethacrylate (PMMA), calcium phosphate, hyrdroxyapatite-tricalcium phosphate (HA-TCP) compounds, bioactive glasses, polymerizable matrix comprises a bisphenol-A dimethacrylate, thermoset cortical bone void filler, demineralized bone matrix, collagen, gelatin, polysaccharide, hyaluronic acid, keratin, albumin, fibrin and combinations thereof.
19 . A method of treating a spinal condition comprising:
attaching an anterior system between a pair of vertebrae;
extending a posterior motion preservation system between posterior bone segments of the pair of vertebrae; and
augmenting a vertebral body of at least one of the pair of vertebrae with at least one of either a vertebral body augmentation material or an endplate augmentation material.
20 .

21 . The method of claim 19 wherein the endplate augmentation material comprises bone at least one from a group consisting of growth factors, hormones, and cells.
22 . The method of claim 19 wherein the anterior system is loaded in compression.
23 . The method of claim 19 wherein the anterior system is loaded in tension.
24 . A method of treating a spinal condition comprising:
attaching an anterior system between a pair of vertebrae to reinforce or stabilize the anterior motion segment;
extending a posterior motion preservation system between posterior bone segments of the pair of vertebrae to restore or preserve intervertebral height; and
repairing an intervertebral disc with an interbody repair system to preserve motion between the pair of vertebrae.
25 . The method of claim 24 wherein the interbody repair system comprises an elastic or resilient material.
26 . The method of claim 24 wherein the interbody repair system comprises a motion preserving disc prosthesis having at least one articulating surface.
27 . The method of claim 24 wherein the interbody repair system comprises a material injectable into a natural nucleus.
