Effects of unilateral puncture and bilateral balloon dilatation percutaneous kyphoplasty through transverse process-lateral pedicle approach on traumatic reaction and bone cement dispersion in patients with osteoporotic thoracolumbar fractures
Objective To investigate the application effect of unilateral puncture and bilateral balloon dilatation percutaneous kyphoplasty through transverse process-lateral pedicle approach in patients with osteoporotic thoracolumbar fractures.Methods A total of 60 patients with osteoporotic thoracolumbar fractures admitted from June 2019 to June 2022 were selected and divided into control group and observation group according to the difference of operation methods,with 30 cases in each group.The control group was treated with percutaneous kyphoplasty via unilateral transpedicular approach,and the observation group was treated with unilateral puncture and bilateral balloon dilatation percutaneous kyphoplasty through transverse process-lateral pedicle approach.The therapeutic effects of the two groups were compared.Results The operation time and postoperative hospitalization time of the observation group were shorter than those of the control group,the number of intraoperative fluoroscopy was less than that of the control group,and the bone cement diffusion coefficient was higher than that of the control group(P＜0.05).Before and after operation,there were no significant differences in the anterior vertebral height and Cobb angle between the two groups(P＞0.05).After operation,the levels of epinephrine(E),C-reactive protein(CRP)and cortisol(Cor)in the observation group were lower than those in the control group(P＜0.05).There was no significant difference in Oswestry Disability Index(ODI)score between the two groups before operation and at 1 and 6 months after operation(P＞0.05).Conclusion The unilateral puncture and bilateral balloon dilatation percutaneous kyphoplasty through transverse process-lateral pedicle approach for osteoporotic thoracolumbar fractures can shorten the operation time,reduce the number of intraoperative fluoroscopy,improve the diffusion effect of bone cement,decline the traumatic reaction,and accelerate the postoperative recovery.
