数字化技术辅助手术治疗 Pilon 骨折疗效分析

摘要

目的研究数字化技术辅助手术治疗 Pilon 骨折的疗效。方法选取30例 Pilon 骨折患者，随机分为 A 组和 B 组（各15例）。A 组采用数字化技术辅助手术，将患者计算机断层扫描（CT）数据导入Mimics10．01软件进行三维重建，选择合适术式行模拟复位手术，再进行手术治疗；B 组则采用传统的非数字化技术辅助手术。术后第2天，采用放射学疗效评价标准（Burwell-Charnley 标准）评估患者术后骨折复位情况；术后6个月、12个月，采用临床疗效评价标准（Olerud-Molander 主观评分标准）评估患者术后踝关节功能恢复情况。结果术后第2天，A 组解剖复位及功能复位例数多于 B 组，差异有统计学意义（P＜0．05）；术后6个月、12个月，A 组踝关节功能评分高于 B 组，差异有统计学意义（P＜0．05）。结论数字化技术辅助手术治疗 Pilon 骨折可使骨折块更好复位，术后踝关节功能恢复更好。%Objective To study the effects of digital technology in the adjuvant treatment for Pilon fractures.Methods 30 cases of Pilon fractures were col ected and randomly divided into two groups.Group A received operation with auxiliary digital technology including three-dimensional reconstruction and surgery simulation;group B received traditional treatment without digital technology.On the second day after the operation,postoperative fracture reduction was evaluate according to the radiological evaluation criteria (Burwel-Charnley standard).At 6 months and 12 months after the operation,ankle joint function was evaluate according to the clinical evaluation criteria (Olerud-Molander subjective scoring standard).Results The anatomic and functional reduction rate in group A was higher than group B (P<0.05),the ankle function scored higher in group A than group B (P<0.05).Conclusions The perfect reductions and functional recovery of Pilon fractures can be reached by operation with auxiliary digital technology.
