网袋强化椎体成形术与经皮后凸椎体成形术在胸腰段骨质疏松压缩骨折中的短期疗效比较.

Objective: To study the difference between bone pouch vertebroplasty and percutaneous balloon dilatation vertebroplasty in the treatment of osteoporotic fracture of spine. Methods: From 2018.01 to 2021.01 95 cases of with osteoporotic fracture of spine were divided into two groups according to different operation ways. 41 patients underwent surgery using bone pouch vertebroplasty (mesh bag group), while 54 patients underwent surgery with conventional balloon dilatation vertebroplasty(PKP group). The VAS and ODI scores in 3days, 3 months after operations were analyzed. Standard thoracolumbar radiography were performed before and after operation. The imaging was compared before and after operation, including anterior edge height, posterior edge height, midline height and cobb angle. The bone cement distribution and the rate of bone cement leakage were evaluated of both groups. Results: 3 days and 3 months after operation, the VAS and the ODI were significant better (P<0.05), while there was no significant difference between 2 groups (P>0.05). In sagittal position, the anterior edge height, posterior edge height, midline height and cobb angle of the two groups recovered significantly compared with those before operation, but there was no significant difference between the two groups (P>0.05). The bone cement distribution and cement leakage rate was significantly better in the mesh bag group (P< 0.05). There was no significant difference in the complications between the two groups. Conclusion: Comparing the conventional PKP method, using the bone pouch vertebroplasty can effective improve bilateral distribution rate of bone cement, and reduce leakage rate of bone cement, which could be further promoted in clinic in osteoporotic vertebral compression fractures.
