Ilizarov技术联合内置物治疗骨不连的应用进展

Application of Ilizarov technique combined with internal implants for bone nonunion

骨不连是骨折术后常见并发症，也是临床医生所面临的难题之一。Ilizamv技术已被证明是治疗感染性骨不连或伴有骨缺损的有效方法，然而，依然存在着患者带架时间长、依从性差等缺点。为解决这一问题，许多学者提出Ilizarov技术联合内置物治疗骨不连，极大缩短患者带架时间，允许患者早期下床活动，取得了良好的效果。本文就Ilizarov技术的牵张成骨机制及Ilizarov技术联合内置物治疗骨不连的应用进展作一综述。

Bone nonunion, a common complication after fracture surgery, is one of the most challenging problems an orthopedist has to face. Although Ilizarov technique has been proved an effective treatment of infected nonunions or bone defects, it bears such shortcomings as long frame-wearing time and poor compliance. In order to tackle them, many scholars have suggested a combination of Ilizarov technique and internal implants for bone nonunion which greatly shortens the time a patient wears the frame and allows for early ambulation, leading to good outcomes. This article reviews the mechanisms of distraction osteogenesis for Ilizarov technique and advances in application of Ilizarov technique combined with internal implants for treatment of bone nonunions.
