摘要 目的探讨3D打印技术辅助跗骨窦入路钢板内固定治疗SandersⅡ、Ⅲ型跟骨骨折的临床疗效。方法观察组纳入自2013-10—2016-10经跗骨窦入路钢板内固定治疗的26例(26足)SandersⅡ、Ⅲ型跟骨骨折,术前采用3D打印技术打印骨折模型进行预复位和固定,并个体化裁剪解剖钢板。对照组选取同期23例(23足)跟骨骨折,采用跟骨外侧L形切口切开复位内固定。结果观察组2例失访,其余患者获得6~12个月随访。观察组术后至踝关节能主动屈伸时间较对照组短,切口并发症明显低于对照组,差异有统计学意义(P<0.05);但2组间术后6个月跟骨Bohler角、Gissane角、高度、宽度、长度,以及末次随访时Maryland评分比较差异无统计学意义(P>0.05)。结论 3D打印技术辅助经跗骨窦入路个体化解剖钢板内固定治疗SandersⅡ、Ⅲ型跟骨骨折可取得与外侧L形切口复位钢板内固定手术相同的疗效,同时可降低切口并发症发生率,促进患者早期功能恢复。
