Abstract

PURPOSE: We analyzed the results and complications of the treatment of segmental fractures of the tibia associated with periarticular fracture by using Ilizarov external fixator.
MATERIALS AND METHODS
We reviewed 17 patients of segmental fractures of the tibia were treated by Ilizarov external fixator and were followed for a minimum one year. There were twelve closed fractures, three type 3A, and two type 3B open fractures. According to Melis classification, there were five type I, four type II, and eight type III. All closed fractures were reduced and fixed with Ilizarov external fixator within seven days. Open fractures were performed immediate wound irrigation and radical debridement and fixed with Ilizarov external fixator. Autogenous iliac bone graft was done in five severe comminuted fractures. Average time in bone graft was 7.5 weeks after operation. We analyzed bony union time according to configuration and site of the fractures, results of the treatment, and complications. The functional outome was assessed with rating system of Tucker.
RESULTS
In all cases, bony union was obtained, and average union time was 20.5 weeks. According to modified Melis classification, our results showed no difference between each criteria with respect to bony union and there was no difference bony union time between proximal and distal fracture site. There were two leg-length discrepancy less than 2 cm, one partial ankylosis of the knee joint, and ten pin tract infections. The functional results was excellent in 11 cases, good in 5 cases, and fair in one case.
CONCLUSION
Ilizarov external fixator can be useful method for the treatment of segmental fractures of the tibia associated with juxtaarticular fracture in respect of bony union and functional results.
