OBJECTIVE
To review the research progress of intramedullary lengthening nail technology.
METHODS
The foreign literature on the development history, types, advantages and disadvantages, indications and contraindications, complications, and effectiveness of intramedullary lengthening nail were reviewed and analyzed.
RESULTS
The intramedullary lengthening nail system mainly includes mechanical type, electric motor drive type, and magnetic drive type. Compared with traditional external fixation and lengthening technology, the intramedullary lengthening nail technology has certain advantages in incidence of complications, bone healing, postoperative functional rehabilitation, incision aesthetics, convenience, and patient satisfaction. However, there are also shortcomings, such as pain, uncontrollable distraction rate, device failure, etc. In the clinical application of intramedullary lengthening nails for limb lengthening, the indications should be grasped reasonably, and the related complications should be prevented and treated.
CONCLUSION
Intramedullary lengthening nails provide a new option for limb lengthening, and the initial effectiveness is good. It is one of the development direction of limb lengthening technology.
目的
回顾髓内延长钉技术的研究进展。
方法
对髓内延长钉的发展历史、类型、优缺点、适应证与禁忌证、并发症及有效性等方面的国外文献进行回顾分析。
结果
髓内延长钉系统主要包括机械型、电动驱动型和磁驱动型。与传统外固定延长技术相比，髓内延长钉技术在并发症发生率、骨愈合、术后功能康复、切口美观度、便利性及患者满意度等方面具有一定优势。但也存在疼痛、牵伸速率不可控、装置故障等缺点。在临床应用髓内延长钉进行肢体延长时，应合理把握适应证，并预防和处理相关并发症。
结论
髓内延长钉为肢体延长提供了一种新选择，初期效果良好，是肢体延长技术的发展方向之一。
