The invention provides a pedicle screw assembly applicable to a spinal fixation surgery together with a guiding device. The pedicle screw assembly comprises a plurality of pedicle screws, parallel correctors and correct linkages. Where in the plurality of pedicle screws drilled into the corresponding spinal respectively. Each pedicle screw is clamped by the corresponding parallel corrector to adjust a direction of U-type fastening groove of each pedicle screw to the same plane. The curvature of the correct linkage is adjusted according to the connection curvature of the U-type fastening groove of each pedicle screw. The correct linkage is disposed in the accommodating portion of each pedicle screw by puncturing of the guiding device, thereby limiting a relative distance of the corresponding spinal.本發明係提供一種椎弓根釘組件,其利用一導引器以進行脊椎固定手術,此椎弓根釘組件包含複數個椎弓根釘、平行校正器以及矯正連桿。其中各椎弓根釘係分別鑽設於相對應之脊柱上,且利用平行校正器夾持相對應之各椎弓根釘,以調整各椎弓根釘之U型定位槽方向於同一平面上。矯正連桿係根據各椎弓根釘的U型定位槽的連線輪廓以調整其曲率,矯正連桿係由導引器以穿刺置放於各椎弓根釘之容置部內,以拘束相對應脊柱之相對距離。8‧‧‧矯正連桿100‧‧‧椎弓根釘200‧‧‧平行校正器300‧‧‧椎弓根釘組件
