Abstract: Objective Exploring the effect of Percutaneous angular vertebroplasty (PCVP) on functional recovery in elderly patients with osteoporotic vertebral compression fractures (OVCF).Methods Retrospective selection of clinical data from 108 OVCF patients admitted to our hospital from August 2020 to December 2022.According to the different surgical methods,52 cases were divided into a control group (percutaneous vertebroplasty) and an observation group (percutaneous vertebroplasty) with 56 cases;Compare the recovery of vertebral body function,imaging related parameters,functional impairment and lumbar function,surgical related conditions,gait,and complications between the two groups.Results The intraoperative blood loss in the observation group was less than that in the control group[(10.65±3.52)ml vs.(13.11±3.66)ml,P＜0.05],the number of intraoperative fluoroscopy was less than that of control group[(14.21±4.27) vs.(17.04±4.25)，P＜0.05],there was no statistically significant difference in the total clinical effective rate between the observation group of 89.28% and the control group of 86.53% (P>0.05).After 2 months of surgery,the imaging related parameters,functional impairment,lumbar function,surgical and gait related conditions in the control group were better than those in the control group (P<0.05).There was no statistically significant difference in the incidence of incision infection,nerve root injury,and recurrent fractures between the two groups (P>0.05),but the leakage rate of bone cement in the observation group was lower than that in the control group (P<0.05).Conclusion Both surgeries can effectively improve the level of lumbar vertebral function in OVCF patients.PVCP has advantages in increasing the height of the anterior and posterior edges of the vertebral body,reducing the Cobb angle,and relatively fewer intraoperative fluoroscopy times and bleeding.The incidence of bone cement leakage is lower,making it more safe.
