As the number of primary and revision arthroplasties performed each year increases, the complexity of the reconstructive efforts also increases. A case of a patient with a total knee arthroplasty complicated with infection, deficient extensor mechanism, bone loss and limb shortening of 5.5 cm is reported. We describe an alternative surgical technique of reconstruction of the knee and lengthening of the limb using the Stanmore Non-Invasive Growing-Distal Femoral Prosthesis. The prosthesis had a magnetic disc attached to a gearbox. The generation of an external electromagnetic field caused the magnetic disc to rotate and lengthen the prosthesis. This reconstructive technique has not been described in the literature.
随着每年初次和翻修关节成形术数量的增加，重建手术的复杂性也在增加。本文报告了一例全膝关节置换术后并发感染、伸肌机制缺陷、骨丢失以及肢体短缩5.5厘米的病例。我们描述了一种使用斯坦莫尔无创股骨远端生长假体进行膝关节重建和肢体延长的替代手术技术。该假体有一个附着在变速箱上的磁碟。外部电磁场的产生使磁碟旋转并延长假体。这种重建技术在文献中尚未有描述。
