Twenty nine cases of segmental tibial fracture were treated at Ewha Womans University Hopital, Department of Orthopedic Surgery, during the period from January, 1970 to December, 1984. The following results were obtained. 1. Most common fracture level was type I, high middle segment, occurred about 12 cases (41.4%). 2. In view of the higher incidence of open fracture (16 cases, 55.1%) and comminuted fracture (22 cases, 75.9%), fracture was caused by high velocity. 3. Various external and internal fixation methods were applied, but higher union rate was seen in the cases of Küntscher nailing and plating with bone graft. 4. Excluding the cases of type V, average union rate was 28.5 weeks and open fracture (ave. 29.6 weeks) required more longer union rate than closed fracture (ave. 26 weeks). 5. Higher rate of complication (21 cases, 72.4%) was noted than other types of tibial fracture. 6. Good result was obtained for treatment of 5 cases of delayed union or non-union by plating and bone graft than any other methods.
