Abstract
Objective:To investigate the effect of biased distribution of bone cement during unilateral percutaneous vertebroplasty(PVP)on the efficacy and prognosis of patients with osteoporotic vertebral compression fractures(OVCF).Method:A total of 127 patients with OVCF who were treated in the Qiannan Buyi and Miao Autonomous Prefecture People's Hospital from November 2020 to November 2023 were selected and divided into observation group(over the center line group,61 cases)and control group(without over the center line group,66 cases)according to the symmetrical distribution of bone cement on the anterior-position X-ray film.Pain visual analogue scale(VAS),Oswestry disability index(ODI),vertebral correction at different time points and adverse events were compared between the two groups.Result:At 1 month and 3 months after operation,VAS scores and ODI scores of the two groups were decreased compared with those before operation,and the observation group was lower than the control group,the differences were statistically significant(P<0.05).At 3 months after surgery,VAS score and ODI score of two groups were lower than that of 1 month after surgery,and the observation group was lower than the control group,the differences were statistically significant(P<0.05).At 1 month and 3 months after surgery,the ratio of vertebral anterior margin height increased and the Cobb angle decreased after local injury in both groups compared those before surgery,and the ratio of vertebral anterior margin height in the observation group was greater than that in the control group,while the Cobb angle after local injury was smaller than that in the control group,the differences were statistically significant(P<0.05).At 3 months after surgery,the ratio of vertebral anterior margin height increased in both groups,and Cobb angle decreased in both groups after local injury compared with 1 month after surgery,and the observation group was better than the control group,the differences were statistically significant(P<0.05).At 3 months after surgery,the incidence of bone cement leakage and recollapse of injured vertebra in the observation group was lower than that in the control group,the differences were statistically significant(P<0.05).There was no significant difference in the incidence of adjacent vertebral fracture between the two groups(P>0.05).Conclusion:The biased distribution of bone cement after unilateral PVP surgery in OVCF patients can affect the therapeutic effect.Among them,the effect of bone cement passing through the midline after surgery is better than that of bone cement not passing through the midline,which significantly reduces patient pain,improves vertebral correction,and effectively reduces the rate of bone cement leakage and the incidence of recollapse of injured vertebrae.关键词
