Application of Ilizarov technique combined with internal implants for bone nonunion

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.
