2005 Comparison of ASF versus PSF with Thoracic Pedicle Screws for Treatment of Lenke I AIS Curves AAOS

Description: Poster Board Number: P301 Spine Benjamin Potter, MD Washington DC (n) Lawrence G Lenke, MD Saint Louis MO (a,e -medtronic sofamor danek) Timothy R Kuklo, MD Rockville MD (a-Medtronic Sofamor danek) We compared 20 ASF patients with Lenke type I AIS to 20 curve-matched patients treated with PSF with thoracic pedicle screws (TPS). PSF/TPS demonstrated greater MT (p=0.009) and TL-L curve correction (p=0.03), as well as greater improvement in rotation and thoracic torsion as assessed by correction of rib hump (p=0.005) and the apical vertebral body-rib ratio (p<0.0001).
