Values are presented as mean±standard deviation. Patients of RC group, who underwent corrective surgery and fusion with instrumentation, were excluded in this comparison.
TKLA, thoracolumbar kyphosis angle; SVA, sagittal vertical axis; T0, before vertebroplasty, T1, immediately after vertebroplasty; T2, 1 year after vertebroplasty; T3, 2 years after vertebroplasty; RC group, recollapsed group; NC group, noncollapsed group.
