Abstract: Thoracic pedicle screw constructs can be safely used for large-magnitude curves. Curve correction (68%) is powerful for these curves, which are stiff and difficult to manage. Correction should be performed carefully with consideration given to convex compression for cases with concomitant hyperkyphosis for these "at risk" spinal cords. Screw accuracy (96.3%) was excellent in this review. The authors found that screws can consistently be placed according to the preoperative plan even in these large-magnitude cu… Show more

“…The probable reason for that might be the narrow pedicle size in mid thoracic level that has been reported in the literature. Kuklo et al [25] reported 96.3% safety in putting pedicle screws in patients with curves[90°a nd concluded that even in large magnitude curves, thoracic pedicle screws can be placed safely. We also compared misplacement of pedicle screws depending on the severity of deformity, and did not fiund significant (P = 0.35, ChiSquare test) difference.…”

“…The groups were similar with respect to Lenke classification. The average age for the cohort was 14.1 (range [10][11][12][13][14][15][16][17][18][19][20] years with a preoperative Cobb angle of 62°(range 40°-85°). There was no difference between the groups with respect to average patient age or preoperative Cobb's angle (P = 0.43, P = 0.66, respectively) ( Table 1).…”

“…Pedicle screws offer three-column fixation and reportedly provide curve correction, maintenance of correction, lower pseudarthrosis rates, fewer implant failures, and fewer postoperative bracing requirements than conventional hook and wire constructs [7,9,16,22]. Additionally, the safety of pedicle screws has been well documented with several large series of patients with AIS undergoing correction with minimal neurologic or visceral complications [13,23,24].…”

“…When pedicle screws are placed accurately, they should be completely contained within the pedicle, whereas hook insertion necessitates canal intrusion of approximately 30% [2]. Also, hooks are more prone to shift during correction maneuvers [8,9]. Another benefit of the more rigid stabilization offered by pedicle screw fixation is the ability to use shorter constructs to achieve deformity correction, thus preserving more motion segments than other techniques and potentially decreasing postoperative back pain [3,16,22].…”
