克氏针阻挡螺钉技术治疗胫骨干骺端骨折

目的：探讨采用克氏针作为临时阻挡螺钉结合扩髓交锁髓内钉内固定技术治疗胫骨干骺端（AO 43A）骨折的临床疗效.方法：自2011年3月至2012年6月,采用胫骨交锁髓内钉结合阻挡螺钉（克氏针）技术治疗胫骨干骺端骨折患者9例,其中男7例,女2例;年龄23～54岁,平均37.4岁.术后观察患者的并发症及X线片表现,并于术后12周时采用美国与踝关节协会踝与后足评分（AOFAS）对功能进行评价.结果：所有患者术后获随访,时间6～40周,平均20.1周.术后所有伤口Ⅰ期愈合,未发生严重肿胀、感染及皮肤坏死等软组织并发症.术后第4、8周复查X线片未发现骨折不稳定、移位现象.术后12周时AOFAS评分95.2±4.6,优7例,良2例.结论：克氏针作为临时阻挡螺钉结合交锁髓内钉对胫骨干骺端骨折的畸形矫正及固定效果良好、方法简单,值得推广.
