Interlocking nails for displaced metaphyseal fractures of the distal tibia.

Metaphyseal fractures of the distal tibia near the ankle joint are difficult to manage. Poor soft tissue coverage and comminution of the fracture complicate open reduction. This prospective study aims to evaluate the practicability of using interlocking nails to treat such fractures. Using the method of closed reduction and internal fixation with a shortened tibial interlocking nail, 20 consecutive cases of distal tibial metaphyseal fractures within 4 cm of the ankle joint line were enrolled from 1997 to 2001. All patients received regular post-operative radiographic check-up and the ankle function was evaluated with the Iowa Ankle-Evaluation rating system. Our result was satisfactory and all of the fractures united solidly with a mean union time of 17.2 weeks. No major complication occurred. We conclude that tibial interlocking nailing is a reliable and safe method for managing metaphyseal fractures of the distal tibia near the ankle joint.
