下肢不等长对于小儿骨科医生是一个极具挑战性的课题，可引起跛行、背痛、髋关节发育不良及脊柱侧弯等问题。传统的外固定架延长术存在许多并发症，如关节僵硬、肌肉挛缩、针道感染以及给不适体验感。目前髓内肢体延长术已经成为外固定装置之外的一个有价值的选择，可以消除临床上对于外固定装置的依赖性和减少并发症。本研究综述髓内延长装置临床应用经验，以期为儿童下肢畸形的矫正提供以参考。

Leg length discrepancy has remained a great challenge for pediatric orthopedic surgeons. Its major symptoms include lameness, back pain, hip dysplasia and scoliosis. Conventional limb lengthening with an external fixator is associated with joint stiffness, muscle contracture, pin site infection and uncomfortable experiences. Currently intramedullary limb lengthening has become a valuable alternative to external fixation so as to eliminate clinical dependence on external fixation and minimize complications. This review summarized clinical experiences of intramedullary lengthening for providing references for correcting lower limb deformity in children.
