经皮克氏针撬拨复位内固定治疗儿童跟骨关节内骨折的疗效分析

目的：介绍经皮克氏针撬拨复位内固定治疗儿童跟骨骨折,评估该方法的临床疗效。方法：2001年3月至2009年2月,采用经皮克氏针撬拨复位内固定治疗儿童跟骨关节内骨折12例（13足）,其中男8例,女4例;年龄3～14岁,平均8.7岁。骨折按Essex-Lopresti分型：舌型骨折5足,压缩型骨折8足。按Sanders分型：Ⅱ型9足,Ⅲ型4足。手术前后摄X线片,比较跟骨B觟hler角和Gissane角的恢复情况,疗效评价采用Maryland足部评分系统。结果：所有患者均获随访,时间16～71个月,平均35.9个月。骨折均获愈合,无创口愈合不良、坏死感染发生。术前B觟hler角为（19.7±5.3）°,术后为（32.6±3.7）°;术前Gissane角为（137.3±7.5）°,术后为（125.4±2.9）°,上述影像学测量结果与术前比较差异均有统计学意义（P〈0.01）。Maryland评分92～100分,平均（96.3±2.4）分。结论：经皮克氏针撬拨复位内固定术,软组织损伤小、固定可靠、疗效满意,是儿童跟骨关节内骨折有效的微创治疗方法。
