治疗胫骨骨折不愈合的正中植骨方法介绍

摘要

引起胫骨骨折不愈合的原因较多,主要有局部感染、软组织缺损、骨缺损、骨折对位不良、骨端髓腔闭塞以及损伤的严重程度等.正中植骨方法(Central bone grafting)治疗选择性胫骨骨折不愈合优于其他治疗方法,并发症较低.该方法采用外侧入路,经腓骨的前侧进入,将取自髂骨的新鲜自体骨植在胫腓骨之间和胫骨不愈合平面的上下端.应用内固定有利于纠正骨折畸形和促进骨折愈合.正中植骨技术是治疗胫骨不愈合安全有效的方法.%Nonunion of the tibia fracture may be caused by local infection,soft tissue defect,bone defect,fracture malaignment, bone marrow cavity block and degree of injury and so on. For less complications, central bone grafting is better than other methods for the treatment of selected nonunions of the tibia fracture. This procedure is performed through lateral approach, anterior to the fibula. Fresh autogenous bone from the iliac crest is used to form a central bridge between the tibia and fibula and the nonunion of the tibia at top and below. Application of internal fixation is beneficial to correct deformity and promote fracture healing. Central bone grafting is a safe and effective treatment for nonunions of the tibia.
