Preoperative and postoperative radiographs of curves treated with a hook construct (a, b) and with a pedicle screw construct (c, d). Initial and corrected curve magnitudes were similar (hook construct, 70° corrected to 23°; screw construct, 70° corrected to 17°). The hook construct (b) cost averaged $10,934.28 and the pedicle screw construct (d) cost averaged $26,341.32
