[Abstract] Objective To explore the effects of percutaneous kyphoplasty（PKP） and percutaneous vertebroplasty （PVP） in the treatment of thoracic compression fractures in the elderly. Methods Eighty elderly patients with thoracic compression fractures who were treated in our hospital from January 2019 to September 2020 were selected and divided into the PVP group and the PKP group according to surgical differences，with 40 patients in each group. The intraoperative amounts of bone cement injection， intraoperative fluoroscopy time， operative time，incidences of postoperative complications， and visual analogue scales （VAS）， anterior edge vertebral heights and Cobb Angles of the injured vertebra before and 3 months after surgery were compared between the two groups. Results The injection amount of bone cement in the PVP group was （4.79±0.92） mL， which was lower than that （5.78±0.89） mL in the PKP group; the fluoroscopy time （8.14±1.02）min and operation time （28.15±6.63）min were shorter than （9.94±1.38）min and （35.84±6.98） min in the PKP group; the differences were statistically significant （P<0.05）. The incidence of postoperative complications in the PVP group was 27.50%， which was higher than the PKP group of 10.00%， and the difference was statistically significant（P<0.05）. No statistical significances were observed in VAS scores， anterior vertebral heights and Cobb Angles between the PKP group and the PVP group before surgery （P>0.05）. Three months after operation， in the PKP group， the height of the injured anterior vertebral body， （27.27±2.04）mm， was higher than （22.45±2.47）mm in the PVP group， and the Cobb Angle， （10.25±1.22）°， was lower than （13.42±1.73）° in the PVP group，with statistically significant differences （P<0.05）. Conclusion PKP can effectively restore the height of the compressed vertebral body and reduce the leakage rate of bone cement. The operation time of PVP is short， so PKP is the first choice for patients with good physical conditions clinically， while PVP is the first choice for patients with less severe vertebral compression and relatively small Cobb Angles.
