科学领域:

  • 整形外科手术 整形外科手术
  • 生物材料工程 生物材料工程
  • 3D打印技术的使用

背景情况:

  • 骨和月球骨折很常见,传统治疗手骨硬化导致并发症.
  • 使用患者特定植入物的手腕骨置换是一种新兴的替代方案.
  • 三维 (3D) 打印的提供了出色的生物相容性和解剖学定制性.

研究的目的:

  • 用3D打印假肢替换骨后评估手功能和与假肢相关的结果.
  • 评估这种新治疗手腕骨髓缩的疗效.

主要方法:

  • 七名患有手腕骨髓缩的患者使用3D打印的假肢进行了手腕骨置换.
  • 术前和术后的手腕功能使用DASH,梅奥手腕得分和视觉模拟尺度 (VAS) 来评估疼痛.
  • 测量了运动范围 (ROM),握力和捏力;X射线图评估了假肢的稳定性.

主要成果:

  • 随访时间平均为19.6个月;手术手腕与对方手腕相比,握力/捏力或ROM没有显著差异.
  • 在手术后的VAS,DASH和Mayo手腕得分中观察到显著的改善,表明疼痛减少和功能增强.
  • 所有的假肢都保持稳定,没有并发症.

结论:

  • 3D打印的假肢是有效的手骨替代,恢复功能和稳定性在患有手骨缩的患者.
  • 这项技术有可能对复杂的解剖结构和手腕以外的不规则骨缺陷进行个性化治疗.
  • 3D打印代表了个性化医学和精确的骨科干预的重大进步.
