Pedicle Screw-Based Posterior Dynamic Stabilization: Literature Review

Table 2

Indications for posterior dynamic stabilization.

(i) Primary indication: treatment of spinal instability
(a) Activity related mechanical back pain secondary to disc/facet degeneration (disc degeneration, facet degeneration, degenerative spondylolisthesis)
(b) Prevent accelerated degeneration to an adjacent motion segment with signs of early degeneration
(ii) Secondary indications: prevention of spinal instability
(a) Laminectomy
(b) To achieve solid fusion—free from stress shielding
(iii) Future indications:
(a) Supplement TDR to achieve total joint replacement
