PURPOSE: We analyzed the result of treatment for most distal extraarticular tibial fracture using interlocking intramedullary nail. MATERIALS AND METHODS: From January 1999 to April 2002, 8 patients who had most distal tibial fracture were treated by interlocking intramedullary nailing. The duration of follow-up was more than 12 months. The mean age was 41.5 years old. There were 5 males and 3 females. During follow-up period, we evaluated the bone union, range of motion of knee and ankle joint and gait pattern. RESULTS: The average distance from fracture line to ankle joint line was 1.1 cm. The bone union was achieved at average 18.6 weeks. At the last follow-up, there was no limited motion on knee. But at one case, ankle range of motion was limited from 5 degree extension to 35 degree flexion. There was no gait disturbance. CONCLUSION: Interlocking intramedullary nailing can be recommendable and useful in the most distal tibial fractures.
