INTRODUCTION: Incidence of open fractures of the long bones is increasing due to the increase in road traffic accidents (RTA) which leads to an increased incidence of complex non-unions of long bones. Patients are usually operated many times for fracture fixation (and healing) or to eradicate infection, which causes soft tissue scarring and devitalization of any surviving bone. OBJECTIVE: In this study, we assess the outcome of the Limb reconstruction system in tibial infected non-union and open tibial diaphyseal fracture with bone loss. METHOD: It is a prospective study conducted on 15 patients and patients included in this study having compound fractures of shaft tibia with bone loss classified by Gustilo-Anderson open fracture classification. With the defect in the distal tibia, proximal corticotomy 1.5 cm distal to the last screw in the proximal clamp and proximal to distal transports were done and vice versa. All patients were evaluated with the ASAMI scoring system into bone results and functional results. RESULTS: In the majority of patients, the injury was caused by road traffic accidents 80% of cases. Out of 15 cases, 2 belong to the upper 3rd, 9 cases belong to the middle 3rd and 4 cases belong to the lower 3rd of shaft tibia. The union time ranges from 4 to 11 months but the maximum union was achieved in 7-9 months in 8 (53.33%). Pin tract infection was reported in two (13.33%) patients who became better with regular dressing. Ankle stiffness was present in one case (6.67%), most probably due to improper physiotherapy.According to ASAMI Criteria excellent radiological results were present in 11 (73.33%) cases, good results were found in 4 (26.67) cases and excellent functional results were observed in 7 cases (46.67%) and good results were found in 8 (53.33%) cases. Infection was cured in all patients and did not recur till the last follow-up. CONCLUSIONS: Advantages of rail fixator include less invasive surgery, early weight-bearing, less infection, less blood loss, prevention of diffuse osteoporosis and atrophy, preservation of limb function, no need for bone grafting, correction of deformity during the process of healing, thus no need for a second surgery. Non-union, bone defect, and deformity can be corrected simultaneously. Hence, we recommend the use of this system (rail fixator) especially for infected non-union of long bones and compound fractures with bone loss.
