【摘要】 目的评价锁骨中段骨折后经非手术治疗发生骨折不愈合的风险因素。方法本研究回顾性分析经非手术治疗的145例锁骨中段骨折患者,其中16例患者不愈合。使用单变量和多变量分析来评估可能导致骨折不愈合的风险因素。结果通过单变量分析,不愈合明显增加的风险因素包括年龄、性别、吸烟、骨折移位和粉碎性骨折,差异有统计学意义(P<0.05)。多变量分析显示吸烟、骨折移位和粉碎性骨折是独立的风险因素。结论锁骨中段骨折经非手术治疗不愈合的风险因素是多方面的,吸烟、骨折移位和粉碎性骨折是不愈合的独立风险因素。更多还原

【Abstract】 Objective To discuss the risk factors of mid-shaft clavicular fractures of nonunion after nonoperative treatment. Methods We per formed a retrospective study of a series of 145 patients with a radiographically confirmed fracture of the mid-shaft clavicle,which was treated nonoperatively. 16 patients underwent nonunion. The influences of several potential risk factors that might affect the nonunion were assessed using bivariate and multivariate analyses. Results By analysis,the risk of nonunion was significantly increased by several intrinsic risk factors including age,sex,smoking,displacement of the fracture and the presence of comminution for all(P<0.05). On multivariate analysis,smoking,fracture displacement and comminution of fracture were identified as independent predictive factors. Conclusions The risk factors for nonunion after nonoperative treatment in mid-shaft clavicular fractures are multifactorial. Smoking,fracture displacement and comminution of fracture are independently predictions for an individual likelihood of nonunion.更多还原
