Background: Management of open tibia shaft fractures is frequently laden with complications. Hence this places an enormous burden on the patient and the surgeon alike. The study objective is to determine the union and non-union rate, and associated complications encountered in the management of open tibia shaft fractures using the Ilizarov frame fixator and Linear rail system [LRS] in Ibadan, Nigeria. Research Method: This is a follow up study to our previous prospective study involving thirty (30) patients of both sexes, divided into two (2) groups; Ilizarov frame fixator group and LRS group. All patients had open tibia shaft fractures of Gustillo-Anderson Class [GA II-IIIB]. The union rate, non-union rate, associated complications noted while on the respective devices as well as the mean total cost implication of managing these open tibia fractures using the Ilizarov frame fixator and LRS respectively were all assessed. Result: The union rate in the LRS group was 86.7% while the non-union rate was 13.3%. In the Ilizarov group, the union rate was 93.3% while the non-union rate was 6.7%. The mean total cost implication for the management of open tibia shaft fractures using LRS and Ilizarov frame fixators were N455,960.0±46,967.3 and N505,614.3±113,345.9 respectively. There is no significant difference noted in the union rate, non-union rate. Conclusion: This study has shown that management of open tibial shaft fractures using either Ilizarov frame fixator or Linear rail system [LRS] is very cost effective especially in a resource poor country like Nigeria.
