Intramedullary magnetic lengthening nails represents a marked advance in the process of limb lengthening, reducing the complications associated with other methods, and improving patient's comfort. However, one important limitation is its lengthening ability, especially when it comes to short bones. Previous reports have shown techniques that may allow further lengthening but at a cost of having to carry out repeated procedures, requiring the use of other devices, and submitting the patient to long-winded surgical procedures. This report presents a novel technique to achieve lengthening beyond the initial reach of the nail, in a simple and quick procedure, without the need of implanting any additional devices.
髓内磁伸缩钉在肢体延长过程中代表了显著的进步,减少了与其他方法相关的并发症,并提高了患者的舒适度。然而,其延长能力是一个重要的局限性,尤其是在涉及短骨时。之前的报告已经显示了一些技术,这些技术可能允许进一步的延长,但代价是需要进行重复的手术,需要使用其他设备,并使患者接受冗长的手术过程。本报告介绍了一种新的技术,可在简单、快速的手术过程中,在不植入任何附加装置的情况下,实现超出初始钉长度的延长。
