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
医疗成像医学成像

背景情况:

对失败的全关节置换术 (TAR) 的修订提出了重大挑战,并增加了患者的发病率.
对末期关节关节炎 (ESAA) 的 TAR 越来越受欢迎,需要有效的修订策略.
针对特定患者的定制3D打印全脚全骨 (TATR) 假肢为修改TAR提供了一个潜在的解决方案.

研究的目的:

评估定制3D打印TATR假肢的临床和放射性结果,这些假肢用于接受失败的初级TAT修复的患者.
在一个需要修订的独特患者子组中评估最低2年的结果.

主要方法:

对19名患有ESAA和失败的初级TAR的患者进行了回顾性分析,他们接受了TATR.
利用基于手术前CT分析的3D打印植入物进行定制组件设计.
使用PROMIS评估患者报告的结果,并通过MDTA,TTA和STA进行X射线对齐.

主要成果:

在TATR后的所有PROMIS领域的统计学上显著改善.
实现了100%的短期存活率,两名患者 (11.0%) 需要因并发症重新手术.
在术前与术后的放射学对齐 (MDTA,TTA,STA) 没有显著变化.

Ankle Joint

Ankle Joint

The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...
