Abstract:Objective: To investigate the safety of three-point reduction combined with percutaneous balloon kyphoplasty (percutaneous kyphoplasty, PKP) in the treatment of thoracolumbar osteoporotic vertebral compression fracture (OVCF) with posterior wall rupture. sex and effectiveness. Methods: A retrospective analysis of 95 patients with OVCF admitted to our hospital from January 2019 to October 2020, including 12 cases of OVCF with posterior vertebral wall rupture (rupture group), and 83 cases of OVCF without posterior wall rupture (no posterior wall rupture). rupture group). The patients in both groups were treated with three-point reduction first and then with PKP technique. The general data (age, gender, segment, etc.), perioperative data (reduction time, fluoroscopy times, bone cement leakage, etc.), preoperative and postoperative low back pain visual analogue scale (Visual Analogue Scale, VAS), Oswestry Disability Index (ODI), anterior height of injured vertebral body, local Cobb angle (o) and so on. Results: The preoperative VAS score and ODI of the two groups were significantly decreased compared with the corresponding indexes at each postoperative time point (P<0.05). All patients successfully completed the operation, and no serious surgical complications occurred. Bone cement leakage occurred in both groups after operation, and there was no statistical difference in the rate of bone cement leakage (p>0.05). The height of the anterior vertebral body in both groups was significantly increased after operation (P<0.05), and the local Cobb angle (o) was significantly decreased after operation (P<0.05). Conclusion: Three-point reduction combined with PKP technique is safe and effective in the treatment of OVCF, especially in patients with OVCF with rupture of the posterior wall of the vertebral body, which can restore the height of the vertebral body and relieve pain.
