科学领域:

  • 整形外科手术 整形外科手术
  • 生物医学工程 生物医学工程
  • 医疗器械创新 医疗器械创新

背景情况:

  • 在复杂的肘部损伤中,三维 (3D) 打印的引导板有助于定位外部固定器的旋转轴.
  • 之前的研究表明这些指南的安全性和有效性.

研究的目的:

  • 为了比较有和没有3D打印指导板辅助旋转轴定位的患者之间的手术结果.
  • 评估对针放置时间,光学曝光和肘部运动范围 (ROM) 的影响.

主要方法:

  • 一项涉及20名患有复杂肘部骨折脱位或创伤后肘部硬 (PTES) 的患者的比较研究.
  • 患者被分为自由手组 (n=10) 和指导模板组 (n=10).
  • 伤害包括体后中旋转不稳定性 (VPMRI),可怕的三合体损伤 (TTI) 和PTES.

主要成果:

  • 导航模板组显示了显著更短的引脚放置时间 (6.80±1.32分 vs 26.00±9.44分,P<0.0001).
  • 在指导模板组中记录的光照射次数较少 (3.60±1.27比41.90±14.80,P<0.0001).
  • 肘部关节的ROM在两组之间是可比的 (137.40±4.40°对132.60±6.48°,P=0.069).

结论:

  • 3D打印的指南模板显著减少了钉子放置时间和光照射.
  • 这些指南提高了复杂的肘部伤害治疗中的手术效率和安全性.
  • 使用3D打印指南不会影响手术后的肘部关节ROM.
