The Relationship Between Several Factors And Postoperative Pain Relief Of PKP In The Treatment Of Thoracic And Lumbar Compression Fractures

Objective:By observing and analyzing the postoperative pain of thoracic and lumbar c ompression fractures,assess the relationship between postoperative pain relief of percutan eous kyphoplasty(PKP) and several factors of gender,surgery approach,bone density,bon e cement injection volume.Methoch:During the period from March 2013 to March 2015.fifty suitable patients with fresh single osteoporotic vertebral compression fracture at the Department of Minimall y Invasive Spine Surgery of Putian CollegeAffiliated Hospital in this study.This suitabl e patients were executed unilateral or bilateral surgery of PKP in need.Recorded and collected the research date of pain relief in time of preoperation,postoperation and stan d 5 minutes after operation.Pain was expressed in terms of visual analogue scale (VA S).After operation,patients were assigned to tow group by gender,surgery,approach,bon e mineral density and the volume of bone cement injectionjust as,male group and female group,better mineral density group and poor mineral density group,unilateral surgery group and bilateral, surgery group,larger cement injection group and smaller cement inje ction group.By sorting, comparison and analysis the study data,objectively evaluated th e relationship between postoperative pain relief of PKP and several factors of gender,su rgery approach,bone density,bone cement injection volume.Mean and standard deviation were calculated for all date.Raw date was analyzed with Statistic Package for Social Science(SPSS version 18.0).Mann-Whitney test were used to evaluate differences betwe en groups.Statistical significant differences was set at P<0.05.Very significant difference s was set at P＜0.01.Results:BMD better group get better postoperative pain relief than BMDpoor group.Th e differences of Pain score of both group of Preoperation-deduce-postoperation-VAS an d Preoperation-deduce-postoperation(stand 5 minutes)-VAS were statistically significant, (P<0.05).Male group get the same postoperative pain relief with female group.The diff erences of Pain score of both group of Preoperation-deduce-postoperation-VAS and Pre operation-deduce-postoperation(stand 5 minutes)-VAS were not statistically significant,(P> 0.05).Unilateral surgery group get the same postoperative pain relief with bilateral surg ery group.The differences of Pain score of both group of Preoperation-deduce-postoper ation-VAS and Preoperation-deduce-postoperation(stand 5 minutes)-VAS were not statistic ally significant,(P>0.05).Larger cement injection group get the same postoperative pain relief with smaller cement injection group.The differences of Pain score of bothgroup of Preoperation-deduce-postoperation-VAS and Preoperation-deduce-postoperation(stan d 5 minutes)-VAS were not statistically significant,(P>0.05).Conclusions:1.Postoperative pain relief of PKP have a connection with BMD T-score in the treatment of vertebral compression fractures.2.Postoperative pain relief of PKP h ave no connection with gender,surgery approach,and the volume of bone cement injectio n in the treatment of vertebral compression fractures.
