Saved distal fusion levels.

<p>A case where one level was saved. <b>(A)</b> A male AIS patient with a preoperative standing coronal Cobb angle of 61.6 degrees from T5-T12. <b>(B)</b> His standing sagittal Cobb angle from T5-T12 was 5.1 degrees. <b>(C)</b> Fulcrum bending radiograph demonstrated a curve of 31.3 degrees. Last follow-up <b>(D)</b> standing coronal Cobb angle was 26.8 degrees and <b>(E)</b> standing sagittal Cobb angle was 4.5 degrees.</p

Fulcrum bending radiograph.

<p>The patient is positioned on the lateral decubitus position. A padded cylinder (fulcrum) of appropriate size is placed on the side of the curve at the level of the rib corresponding to the apex of the curve. For example, if the apex vertebra of the curve is at T9, the fulcrum should be placed at the T9 rib. The fulcrum should be positioned to allow the shoulder and the pelvis to be lifted off the table.</p
