Abstract
Insertion methods for placing dynamic interbody devices between a first vertebra and a second vertebra using a posterior approach are provided. In an embodiment, the insertion method may be based on the first vertebra. A bridge assembly may be attached to tap shafts positioned in the first vertebra. The bridge assembly may establish an insertion angle of implants into a disc space between the vertebrae. In an embodiment, the insertion method may be based on the position of expandable trials positioned between the vertebrae. The trials may be positioned and a bridge assembly may be coupled to the expandable trials and taps positioned in the first vertebra. One or more posterior stabilization systems may be coupled to the vertebrae after insertion of the dynamic interbody devices between the vertebrae.
