  		Fig 1. Lines used to measure retropulsion of the bone fragment over sagittal CT scans. Retropulsion is measured by using a distance from the line between the posterior margin of the adjacent vertebral bodies (arrowhead) and the bony fragment (arrow).

A, Sagittal T2-weighted image 6 days before vertebroplasty shows a severe compression fracture of the L2 vertebral body. Retropulsion of the bony fragment is noted, measuring approximately 5.4 mm (arrow). High signal intensity is seen in the anterior portion of the vertebral body (arrowhead).

B, Sagittal reformatted CT scan after vertebroplasty shows sufficient cement filling in L2 vertebral body (arrowhead). No prominent worsening of retropulsion is noted (arrow).
