Relation between Bone Cement Dispersion Type and Fractured Vertebral Height Loss after Percutaneous Vertebroplasty
摘要
Abstract
Objective To investigate the relationship between bone cement dispersion types and fractured vertebral height loss after percutaneous vertebroplasty (PVP).Methods A retrospective analysis was made to the clinical data of 79 elderly patients with single segment vertebral compression fracture undergoing PVP during the period from June 1,2012 to June 1,2016;according to the X-ray radiographs and CT scans,all subjects were divided into 2 groups:mass type group [n =30,average age:(79.5 ± 8.6) years] and diffusion type group [n =49,average age:(76.0 ± 8.8) years];the fractured vertebral height compression rate,the volume of bone cement filled,the operation time length,the fractured vertebral height restoration rate,6-month postoperative vertebral height loss rate,the postoperative local Cobb angle and bone cement leakage rate in the 2 groups were recorded respectively and a comparative study was made.Results There was no significant difference in age,sex,body mass index,the levels of serum calcium and phosphorus,bone mineral density,fractured vertebral height restoration rate and postoperative local Cobb angle between the 2 groups (P＞ 0.05) while the preoperative fractured vertebral height compression rate and postoperative vertebral height loss rate in diffusion type group were significantly lower than those in mass type group (P＜0.05).Conclusions Bone cement mass dispersion maybe an important risk factor for fractured vertebral height loss after PVP.关键词
