目的 :分析BMD对骨质疏松性骨折患者术后再发骨风险的评估价值。方法 :回顾性分析2014年3月~2015年6月在我院接受PVP治疗的128例骨质疏松性骨折患者的临床资料,根据其术后是否再发骨折分为再发骨折组和未再发骨折组,比较两组患者椎体前缘压缩度、后凸Cobb’s角的差异;比较不同临床特征的PVP术患者再发骨折发生率;分析术后再发骨折的危险因素。结果 :两组患者手术前椎体前缘压缩度和后凸Cobb’s角无明显差别,手术后两组椎体前缘压缩度和后凸Cobb’s角较术前均明显改善,且未再发骨折组改善更为明显;年龄≥70岁、BMD较低、BMI较低、有椎间盘有无发生渗漏和胸腰段损伤PVP术患者再发骨折发生率较高,差异有统计学意义;由Logistic回归分析结果可知,年龄、BMD和椎间盘有无发生渗漏是PVP患者术后发生再发椎体骨折的危险因素。结论 :骨质疏松性骨折PVP患者再发骨折受年龄、BMD等多种因素影响:BMD越低,发生再发骨折的机率越高。
Objective: To evaluate the value of BMD in evaluating the risk of postoperative bone loss in osteoporotic fracture patients. Methods: The clinical data of 128 patients with osteoporotic fracture treated with PVP in our hospital from March 2014 to June 2015 were retrospectively analyzed. According to their postoperative recurrence or fracture, they were divided into two groups: In the fractured group, the differences of vertebral compression and kyphosis between the two groups were compared. The incidences of recurrent fractures in PVP patients with different clinical features were compared. The risk factors of recurrent fractures were analyzed. Results: There was no significant difference between the two groups in preoperative compression of vertebral body and the Cobb’s angle of kyphosis. The anterior vertebral compressibility and Cobb’s angle of the two groups were significantly improved after operation, Improve more obvious; age ≥ 70 years old, lower BMD, lower BMI, with or without disc leakage and thoracolumbar injury PVP patients with higher incidence of recurrent fractures, the difference was statistically significant; by Logistic regression Analysis results show that age, BMD and disc leakage or not is a risk factor for PVP patients with recurrent vertebral fractures. Conclusion: The recurrence of fracture in patients with osteoporotic fracture PVP is influenced by many factors such as age and BMD. The lower the BMD, the higher the probability of recurrent fracture.
