"Order of screw placement." The order of screws placement for two segments (7 Spinal levels) is shown from left to right representing inferior to superior. Each segment consists of three levels with a skipped level in between each segment. Two standard reduction screws (T10, T9) are instrumented at the inferior levels followed by a MIS reduction screw (T8) at the superior level. The same pattern is seen in the T4-T6 segment. A rod reduction device is shown on the T9 screw which can facilitate seating of the rod when necessary. Open connectors are pictured extending from the MIS screws.
