Abstract
Objective To evaluate the risk factors of secondary adjacent vertebral fractures after percutaneous ky-phoplasty (PKP).Methods 103 cases of vertebral compression fractures caused by osteoporosis in patients with single or multiple line segments PKP retrospective study of treatment for patients with gender,age,body mass index, bone density,vertebral compression injury,with or without scoliosis,the leading edge of the injured vertebra degree of recovery,the amount of bone cement injection,surgical approach (unilateral,bilateral),bone cement leakage (disc) and other data were statistically analyzed.Results 103 cases were followed up for 6 ~15 (9.6 ±2.8)months.27 patients had secondary adjacent vertebral fracture,re-fracture rate was 26.2%.Logistic regression of factors enter the“forward Wald”analysis model showed that bone mineral density,bone cement volume,body mass index and degree of recovery of the injured vertebra leading edge of the risk factors associated with postoperative secondary was adjacent vertebral fractures.Conclusions Over dose bone cement,low body mass index,over restoration of injured vertebra an-terior height and low bone density are the risk factors of secondary adjacent vertebral compression fractures after PKP.关键词
