CASE
We present a case report documenting the retrieval and histological analysis of a porous tantalum (P-Ta) total ankle replacement (TAR) from a 50-year-old woman after a below-knee transtibial amputation. This rare opportunity to examine an intact TAR may help to better understand the implant-bone relationship because it would be in situ.
CONCLUSION
In this case study, we demonstrate bone ingrowth to the first layer of the P-Ta and organized trabecular orientation, suggesting that equal bone load was achieved on the base and the rails in both components using a transfibular surgical approach.
病例报告
我们报告了一例 50 岁女性因膝下小腿截肢后，从其体内取出多孔钽（P-Ta）全踝关节置换（TAR）假体的病例。这是一个难得的机会，可以检查一个完整的 TAR，这有助于更好地了解植入物与骨骼的关系，因为它是原位的。
结论
在本病例研究中，我们发现 P-Ta 的第一层有骨长入，并且骨小梁排列有序，这表明使用经腓骨手术入路，在两个组件的基底和轨道上都实现了相等的骨负荷。
