Abstract: Objective:To explore the clinical effects of Ilizarov bone shortening-lengthening in the treatment of the tibia complicated with soft tissue defect.Methods:Ninety-five patients with tibia complicated with soft tissue defect were randomly divided into the observation group(48 cases) and control group(47 cases).The control group was treated with Ilizarov bone transport,and the observation group was treated with Ilizarov bone shortening-lengthening.The operation index and clinical curative effect between two groups were compared.Results:The hospital stay,and healing time of bone defect and wound closure time in observation group were less than those in control group(P<0.01).The clinical total effective rate in observation group(97.9%) was higher than that in control group(83.0%)(P<0.05).The postoperative infection rate in observation group was significantly lower than that in control group(P<0.05).Conclusions:The Ilizarov bone shortening-lengthening in the treatment of the tibia complicated with soft tissue defect has good effect,less complication and short healing time of bone defect,which can quicken the recovery of patients,and worthy of clinical popularization and application.
