Abstract Objective:To evaluate the clinical efficacy of the sequential infusion of bone cement when percutaneous kyphoplasty(PKP) was conducted for the treatment of osteoporotic vertebral compression fracture(OVCF) with posterior wall bone defects. Methods: Patients with posterior wall bone defects OVCF treated in our department from May 2016 to July 2020 were retrospectively analyzed. A total of 32 patients meeting the inclusion and exclusion criteria were treated by the sequential infusion of bone cement when PKP was applied. The visual analog score(VAS), Oswestry disability index(ODI), Cobb angle and height of injured vertebra were recorded and compared before surgery and 1 and 3 months after surgery. Postoperative bone cement leakage and complications were also recorded. Results:The postoperative VAS,ODI and Cobb angle of injured vertebra were significantly lower than those before surgery(P＜0.05).The postoperative height of the injured vertebra was significantly higher than that before surgery(P＜0.05). However, there was no significant differences between followup results at 1 and 3 months postoperatively(P＞0.05). There were 3 cases (9.38%) of bone cement leakage, without any cases of spinal canal leakage. No surgical complications such as nerve injury and pulmonary embolism were observed. Conclusion:Sequential infusion of bone cement during PKP is a safe and effective surgery for the OVCF with posterior wall bone defects, which could effectively reduce the bone cement leakage.
