Highlights Elaboration of a quantitative database of pedicle screw implantation corridors and morphometric dimensions of the normal thoracolumbar goat spine. The estimating insertion angles for pedicular screw are of approximately 30 ° for the T2-T3 segments, 25 ° for the T4-T5 segments, 23 ° for the T6-T11 segments, 20 ° for the T12-T13 segments, 22 ° for the L1-L3 segments, 24° for the L4 segment and 30° for the L5-L6 segments.
