摘要
目的探讨经皮椎体后凸成形术（percutaneous kyphoplasty,PKP）后继发非手术椎体再骨折的相关因素。方法收集2010年9月—2012年9月因骨质疏松性椎体压缩性骨折行PKP术114例。术后继发非手术椎体再骨折为再骨折组,无再发骨折为未骨折组,进行单因素和多因素分析。结果 98例获得随访,时间为3～15个月。继发非手术椎体再骨折23例,占23.5%。再骨折组和未骨折组在术前伤椎压缩程度、年龄、性别、手术入路、骨水泥渗漏方面差异无统计学意义（P〉0.05）;再骨折组骨水泥量、伤椎前缘高度恢复程度值均高于未骨折组（P〈0.05）;而骨密度T值、体重指数则低于未骨折组（P〈0.05）。骨密度、骨水泥量、体重指数及伤椎前缘恢复程度与术后继发非手术椎体再骨折有相关性。结论骨水泥量过大、低体重指数、伤椎前缘高度过度恢复、低骨密度是PKP术后继发非手术椎体再骨折的相关因素。
Objective To investigate the factors of secondary non-surgical vertebral fractures after percutaneous kyphoplasty（PKP）. Methods Collecting 114 cases of osteoporotic vertebral compression fractures in patients with PKP surgery from September 2010 to September 2012, secondary non-surgical vertebral fractures were re-fracture group, no non-surgical fractures were no-fracture group, then using univariate and multivariate analysis. Results Ninety eight cases were followed up for 3～15 months. 23 cases with non-surgical vertebral fractures secondary, accounting for 23.5%. The level of injured vertebral compression before surgery, age, gender,surgical approach,cement leakage between re-fracture group and no-fracture group have no statistically significant difference（P〉0.05）;bone cement volume, degree of recovery of the injured vertebral anterior height in re-fracture group were higher than that in no-fracture group（P〈0.05）;while T-score of bone mineral density, body mass index in re-fracture group were lower than that in no-fracture group. Bone mineral density, bone cement volume, body mass index and the degree of recovery of the injured vertebra anterior height were related with secondary non-surgical vertebral fractures. Conclusion Excessive bone cement, low body mass index, over leading edge of the injured vertebral height restoration, low bone mineral density are related to secondary non-surgical vertebral fractures after PKP.
