Abstract: Objective：To investigate the clinical effect of percutaneous curved vertebroplasty(PCVP) in the treatment of thoracolumbar osteoporotic vertebral compression fractures.Methods：80 patients with thoracolumbar osteoporotic vertebral compression fractures in our hospital from January 2017 to January 2019 were selected,33 patients(PCVP group) were underwent PCVP operation,27patients(unilateral group) were underwent unilateral approach and 20 patients(bilateral group) were underwent bilateral approach,the operation time,Xray exposure times,the amount of bone cement injection and adverse reactionsand so on were observed,and VAS score and ODI index before surgery,1 week after surgery and 12 months after surgery were observed.Results：The operation time and Xray exposure times of PCVP group were(21.19±3.80)min and(8.89±1.98)times,which were significantly lower than those of bilateral group(P<0.05),but there was no significant difference between PCVP group and unilateral group(P>0.05);There were no significant difference in VAS score and ODI index,tThe anterior and posterior margins of the vertebral body are highly compressible between unilateral group,bilateral group and PCVP group at 1 weeks,12 months after operation(P>0.05);No fracture or collapse occurred again in unilateral group,bilateral group and PCVP group,and no adverse reactions such as cement displacement occurred.Conclusion：PCVP has a good clinical effect in the treatment of thoracolumbar osteoporotic vertebral compression fracture,which is worth clinical use.
