Effect Of Percutaneous Vertebroplasty On Pulmonary Function In Patients With Osteoporotic Vertebral Compression Fracture

Background:In today's society,the aging population in China is increasing,and the incidence of osteoporosis vertebral compression fractures is increasing year by year.Osteoporosis is the pathological basis of osteoporotic vertebral compression fractures.Osteoporosis can lead to progressive bone loss and changes in bone trabecular structure,which can cause vertebral compression fractures of patients with certain external forces.The patient often presents as acuteness lumbago backache,serious person can appear after rachis kyphosis is malformed.If not timely intervention and treatment,lumbar back pain and kyphosis deformity can make patients lose the ability to move,and further can cause a series of complications,such as increased incidence of lung disease,leading to respiratory dysfunction,seriously affecting the quality of life of patients.Percutaneous vertebroplasty(PVP)has been used in China for nearly 20 years in the treatment of OVCF,and the good clinical effect obtained by this technology has been generally recognized in the research reports of many scholars at home and abroad.However,at present,whether PVP can improve postoperative rehabilitation and long-term effects(such as lung function)in patients with osteoporosis vertebral compression fractures has not been clearly determined.Most studies have confirmed that the pulmonary function of patients with osteoporotic vertebral compression fractures has been improved after PVP treatment,and the specific mechanism may be related to pain relief,vertebral height recovery,increased thoracic range of motion,pulmonary ventilation and lung volume.Objective:To investigate the effect of percutaneous vertebroplasty(PVP)on pulmonary function in patients with osteoporotic vertebral compression fractures.Methods:Retrospective analysis of 70 cases of osteoporotic vertebral compression fractures treated with PVP surgery from 2016-09 to 2017-09,compared with preoperative,postoperative 3 days,postoperative 3 months pain VAS score,injured Cobb angle,Forced vital capacity(FVC),forced expiratory volume in 1 second(FEV1),forced expiratory volume in 1 second(FEV1/FVC),maximum ventilation per minute(MVV).Results:All 70 patients were followed up for 3 months.The pain VAS score and the Cobb angle of the injured vertebra were improved at 3 days after operation,and improved at 3 months after operation,and the difference was statistically significant(P<0.05).There was no significant difference in FVC between the 3rd day and the preoperative period(P>0.05).The FVC increased 3 months after operation,and the difference was statistically significant(P<0.05).The FEV1 increased 3 days after operation,and the difference was statistically significant(P<0.05).However,there was no significant difference in FEV1 between 3 months and 3 days after operation(P>0.05).The FEV1/FVC decreased 3 days after operation,and was lower than 3 days after operation.The MVV increased 3 days after operation and 3 days after operation.The difference was statistically significant(P<0.05).Conclusion:Percutaneous vertebroplasty can improve postoperative lung function in patients with osteoporotic vertebral compression fractures,and lung function will be further improved later with the improvement of patients' condition and the increase of daily activity.
