Abstract：Objective To explore clinical effects of percutaneous kyphoplasty (PKP) and pedical-screw internal fixation on elderly patients with thoracic and lumbar vertebral compression fractures.Methods Totally 32 elderly patients with thoracic and lumbar vertebral compression fractures from January 2010 to April 2015 in Kunshan No.4 People's Hospital and the First Affiliated Hospital of Soochow University were divided into PKP group and pedical-screw internal fixation group,with 16 cases in each group.Operation time,postoperative off-bed time,Cobb's angle,vertebral compression ratio,pain visual analogue scale (VAS) score and complication occurrence were analyzed.Results Operation time and postoperative off-bed time in PKP group were significantly shorter than those in pedical-screw internal fixation group [(45.0 ± 1.3) min vs (80.0 ± 3.3) min,(2.09 ± 0.18) d vs (64.00 ± 27.00) d] (P ＜ 0.05).Before operation,Cobb's angles,vertebral compression ratio and VAS score had no significant difference between groups (P ＞ 0.05).One week and 12 months after operation,Cobb's angles and vertebral compression ratio in PKP group were significantly lower than those in pedical-screw internal fixation group[1 weeks after operation:(7 ±4) ° vs (9 ±4) °,(15 ±7)％ vs (17 ±7)％;12 months after operation:(9 ± 4) ° vs (15 ± 7) °,(15 ± 7) ％ vs (24 ± 5) ％] (P ＜ 0.05).One week after operation,VAS scores in PKP group were significantly lower than those in pedical-screw internal fixation group [(1.7 ± 0.7) scores vs (7.0 ±2.1)scores] (P＜0.05).There were no postoperative complications in both groups.Conclusion PKP operation can significantly alleviate pain in elderly patients with vertebral compression fractures;it can also effectively prevent the loss of vertebral height and corrective angle after operation.
