Abstract:

Objective To compare the efficacy of percutaneous kyphoplasty（PKP）with that of percutaneous vertebroplasty（PVP）in the treatment of osteoporotic thoracic vertebral fractures with intercostal pain. Methods A total of 86 patients with thoracic OVCFs and intercostal pain，who had admitted to our hospital from January 2020 to February 2021，were selected and randomly divided into two groups. The PKP group received PKP after postural reduction，while the PVP group underwent PVP alone. Both groups were followed up for 6 months. Surgical duration，length of hospital stay，bone cement injection volume，height ratio of the anterior edge of the impaired vertebrae，kyphotic angle，VAS score，ODI score，and related complications were recorded in the two groups. Results The VAS scores of postoperative intercostal pain and chest and back pain in both groups were significantly improved as compared with the baselines，and the difference was statistically significant（P < 0.05）. The postoper⁃ ative ODI in both groups was significantly improved as compared with the baseline，and the difference was statisti⁃ cally significant（P < 0.05）. The height ratio of the anterior edge of the impaired vertebrae and the kyphotic angle were significantly improved in the PKP group after the procedure，and the difference was statistically significant （P < 0.05）；while the PVP group was improved after the procedure，and the difference was not statistically signifi⁃ cant（P > 0.05）. There were no significant statistical differences between the two groups in surgical duration，length of hospital stay，VAS score and ODI score. The PKP group was better than the PVP group in bone cement injection volume，bone cement leakage，height ratio of the anterior edge of the impaired vertebra，and kyphotic angle of the impaired vertebra. Conclusions Both PKP following postural reduction and PVP alone can effectively treat thoracic OVCFs with intercostal pain. The former is significantly better than the latter in bone cement leakage and recovery of impaired vertebral height and kyphotic angle.
