To summarize the research and clinical application progress of foot lengthening surgery.
Relevant research literature on foot lengthening surgery in recent years at home and abroad was reviewed, and a summary was made from aspects such as the types of lengthening surgery, the types of foot diseases treated by clinical application, effectiveness, and complications.
Bone defects and shortening deformities of the foot are relatively common clinically. As an innovative treatment method, foot lengthening surgery has gradually attracted attention, mainly including the Ilizarov technique and one-stage bone grafting lengthening surgery. The former promotes bone regeneration based on the tension-stress principle and is widely used in the treatment of calcaneal defects and congenital metatarsal brachymetatarsia, achieving good curative effects. However, there are also complications such as pin-tract infection, joint stiffness and contracture, non-union and delayed union of bone, re-fracture, and alignment deviation. The latter has a short treatment cycle, but the lengthening length is limited. Bone graft resorption and soft tissue complications are its main complications.
Foot lengthening surgery will develop towards the direction of personalization, intelligence, and precision. With the help of multi-center research, biological materials, and intelligent technologies, the effectiveness and safety will be further improved to better restore the function and appearance of the foot.
总结足延长手术的研究及临床应用进展。
回顾近年来国内外足延长手术的相关研究文献，从延长手术类型、临床应用治疗的足部疾病类型、疗效及并发症等方面进行总结。
足部骨缺损及短缩畸形在临床上较为常见。足延长手术作为一种创新治疗方法逐渐受到关注，主要包括伊里扎洛夫技术和一期骨移植延长手术。前者基于张力 - 应力原理促进骨再生，广泛应用于跟骨缺损及先天性跖骨短小症的治疗，取得了良好疗效。但也存在诸如针道感染、关节僵硬和挛缩、骨不连和延迟愈合、再骨折及对线偏差等并发症。后者治疗周期短，但延长长度有限。骨移植吸收及软组织并发症是其主要并发症。
足延长手术将朝着个性化、智能化、精准化方向发展。借助多中心研究、生物材料及智能技术，其有效性和安全性将进一步提高，以更好地恢复足部功能及外观。
