Fracture of the tibia is the most common fracture of all long bones, and due to its anatomical property, higher complication rates were reported during treatment. Many treatment modalities were introduced and recent trends in treatment is closed reduction and intramedually nailings. Especially, segmental fracture of the tibia occurs in high energy mechanism. Due to massive soft tissue damage, severe displacement, severe communition, and lack of blood supply at fracture site, treatment will lead to many difficulties. Treating the segmental fracture with plate and screw, massive dissection and periosteal stripping will lead to infection, delayed union, non-union etc., while with external fixator, malunion due to loss of reduction and delayed union and non-union due to lack of stability will likely occur. Treating with intramedullay nails, destruction of endosteal blood supply due to reaming, rotation of middle fragment, and displacement of the comminuted fragments were the problems, but in using Ender nails with closed or minimally open methods, were obtained a good result only preventing the rotation of middle fragment. Authors reported 15 cases of segmental fractures of the tibia treated with Ender nails from July, 1987 to December, 1989. The results were as follows;l. Eleven cases were male and average age was 45.3 years. 2. Eleven cases were closed fractures and most common type was type I as classification by Melis and his associates15). 3. Most common cause of injury was traffic accident (11/15; 73.3%). 4. The most common associated injury was pelvic fracture. 5. Nine complication showed but, only two were clinically significant (1 with non-union and 1 with severe middle fragment rotation). 6. Duration of union of the fracture was 18.2 weeks in clinical and 23.2 weeks in radilogical.
