全距骨置换术的研究进展△

Advances in the study of total talus replacement

摘要:

随着3D 打印技术在临床实践中的广泛应用，使用定制假体进行全距骨置换（total talar replacement, TTR） 已成为治疗踝关节疾病，如距骨缺血性坏死（avascular necrosis, AVN） 和骨关节炎的有效选择。过去20 年来，TTR 手术已取得成功，并且总体存活率令人满意。然而，目前对于距骨置换的研究仍处于初级阶段，需要长期评估其效果。本综述旨在总结有关TTR的文献，并提供历史调查、适应证和禁忌证的变化、3D 打印技术在距骨假体中的应用、存活率以及功能结果方面最新进展。

Abstract:

With the widespread use of 3D printing technology in clinical practice, total talar replacement (TTR) using customized pros-theses has become an effective option for the treatment of ankle disorders, such as talar avascular necrosis (AVN) and osteoarthritis. Overthe past 20 years, TTR procedures have been conducted successfully with a satisfactory overall survival rate. However, the TTR is still in itsinfancy and need to be evaluated over time. The aim of this review is to summarize the literature on TTR and provide an recent advances onhistorical survey, indications and contraindications, the use of 3D printing technology in talar prosthetic manufacture, survival rates, andfunctional outcomes.
