儿童JacobⅡ型肱骨外髁骨折关节造影临床应用

Clinical application of arthrography in JacobⅡhumeral lateral condylar fracture in children

探讨关节造影亚型在儿童JacobⅡ型肱骨外髁骨折的临床应用价值。收集符合纳入标准的患儿资料,共85例。术中根据造影软骨铰链情况将患儿分为JA、JB、JC、JD四个亚组。采用方差分析和t检验对性别、侧别、年龄、受伤距手术时间进行统计学分析。不同治疗方式的性别、侧别、年龄、受伤距手术时间等差异无统计学意义(P>0.05),t检验显示JA组骨折移位程度(2.58±0.41)mm明显小于JB组(3.32±0.50)mm,差异有统计学意义(P<0.05)。术中关节造影亚型可为儿童JacobⅡ型肱骨外髁骨折手术治疗提供参考价值,且在X线上骨折移位程度<3.2 mm时,可行闭合复位克氏针固定。

To explore the clinical value of arthrography in children with JacobⅡtype humeral humeral lateral condylar fracture.A retrospective collection of eligible children with a total of 85 patients was recorded in this study.According to the arthrography results,the children were divided into JA-JD four groups.The variance analysis and t text analyzed the correlation between gender,side,age,time from injury to operation,fracture displacement degree and treatment.There was no significantly difference between gender,side,age,time from injury to operation and treatment(P>0.05).The degree of fracture displacement in group JA was significantly lower than group JB[(2.58±0.41)vs(3.32±0.50),P<0.05].The intraoperative arthrography adds valuable information for the surgical treatment of children with Jacob II humeral lateral condylar fracture.When the fracture displacement below 3.2 mm in X-ray,it is feasible to perform closed reduction and percutaneous pinning.
