Abstract:
OBJECTIVETo study the risk factors of secondary kyphotic angle increment after bone cement vertebroplasty for osteoporotic vertebral compression fractures.
METHODSFrom October 2005 to May 2006, 32 (45 vertebrae) bone cement vertebroplasty procedures were performed. The operation time, injected cement volume, bone mineral density, visual analog scale (VAS) pain score, vertebral height, and kyphotic angle were recorded. The secondary increment of the kyphotic angle was calculated, and correlation analysis and linear regression analysis were performed.
RESULTSThe bone mineral density, the postoperative kyphotic angle and the vertebral midline height were significantly correlated to the secondary increment of the kyphotic angle.
CONCLUSIONLarge postoperative kyphotic angle, poor postoperative recovery of the vertebral midline height, and low bone mineral density are all risk factors of secondary increment of the kyphotic angle.
