Effects Of Bone Density And Fracture Site On Pain After Percutaneous Vertebroplasty

Objective :To investigate the effect of the location and bone density of osteoporosis compression fracture on residual pain,lower back pain and intercostal pain after percutaneous vertebroplasty(PVP).Methods:A retrospective analysis in July 2016 to December 2017 diagnosed with osteoporotic compression fractures and suffer vertebral plasty of 96 patients were followed for more than 1 year of complete information,line visual analogue scale(VAS)pain,bone mineral density and fracture is analyzed with PVP postoperative surgical site under the residual pain,waist pain and pain of the relationship between ribs.Results:A total of 26 patients(27.08%)had residual pain at the operative site after percutaneous vertebroplasty.A total of 14 patients(14.58%)had postoperative lower back pain.And a total of 6 patients(6.25%)had postoperative intercostal pain.The VAS score of residual pain at the fracture site was negatively correlated with the density of the lumbar vertebrae.With the decrease of bone density,the VAS score of the patients increased continuously(r=-0.605,P<0.001).After percutaneous vertebroplasty,the VAS score of residual pain at the fracture site was negatively correlated with the t-value,and with the decrease of the t-value,the VAS score increased continuously(r=-0.0.657,P<0.001).The closer the fracture site is to the lower lumbar spine,the higher the probability of residual pain andlower back pain after surgery,and the more severe the pain.Conclusion:The pain degree of lower back pain and residual pain after percutaneous vertebroplasty is negatively correlated with the density of lumbar vertebrae.The incidence and degree of residual pain and lower back pain after surgery increased continuously as the location of the disease was gradually close to the lower lumbar spine,and the two were positively correlated.
