老年骨质疏松性脊柱骨折微创术后再发骨折的影响因素Logistic回归分析

Logistic regression analysis on the factors of recurrent fractures of elderly osteoporotic spinal fractures after minimally invasive surgery

目的分析老年骨质疏松性脊柱骨折微创术后再发骨折的影响因素。方法对180例老年骨质疏松性脊柱骨折微创术后患者的临床资料进行回顾性分析,总结老年骨质疏松性脊柱骨折微创术后再发骨折的危险因素。结果 180例老年骨质疏松性脊柱骨折微创术后,骨折再发率为14.44%(26/180)。与未再发组比较,再发组女性、年龄>80岁、骨水泥渗漏、BMD T值<-2.5 SD、恢复期意外事故、营养供给不足、钙吸收障碍的构成比更高,遵医嘱服用抗骨质疏松药物的构成比更低(P<0.05);Logistic回归分析结果显示,女性、年龄>80岁、骨水泥渗漏、BMD T值<-2.5 SD、恢复期意外事故、营养供给不足、钙吸收障碍均是再发骨折独立危险因素,遵医嘱服用抗骨质疏松药物是保护因素(P<0.05)。结论女性、年龄>80岁等均是老年骨质疏松性脊柱骨折微创术后患者再发骨折的危险因素,而遵医嘱服用抗骨质疏松药物是保护因素。

Objective To analyze the factors of recurrent fractures of elderly osteoporotic spinal fractures after minimally invasive surgery. Methods The clinical data of 180 patients with elderly osteoporotic spinal fractures after minimally invasive surgery were retrospectively analyzed, and the related factors of recurrent fractures were summarized.Results In 180 patients with elderly osteoporotic spinal fractures after minimally invasive surgery, the rate of recurrent fractures was 14.44%（26/180）. Compared with the no recurrence group, there were higher rates of female, age 80,leakage of bone cement, BMD T -2.5 SD, recovery period accident, insufficient nutrition supply, calcium absorption disorder and lower rate of taking anti-osteoporosis drugs as prescribed in the recurrence group（ P 0.05）. The Logistic regression analysis showed that female, age 80, leakage of bone cement, BMD T -2.5 SD, recovery period accident,insufficient nutrition supply, calcium absorption disorder were independent risk factors of recurrent fractures, and taking anti-osteoporosis drugs as prescribed was protective factor（P0.05）. Conclusion Female, age 80 and so on are the risk factors of recurrent fractures of elderly osteoporotic spinal fractures after minimally invasive surgery, while taking anti-osteoporosis drugs as prescribed is protective factor.
