Background: Hypertrophic nonunion often develops due to improper fracture immobilization or failed internal fixation. Gross mobility at the fracture site interferes with the normal healing process with the formation of fibrocartilage, which fails to mature into solid callus. Aim of the study: The aim of this study was to evaluate distraction osteogenesis by ilizarov ring fixator for hypertrophic nonunion of tibia with deformity and shortening. Methods: This was a quasi-experimental study conducted at National Institute of Traumatology & Orthopaedic Rehabilitation (NITOR), Dhaka, Bangladesh in the period from June 2011 to December 2012. Study population were all the patients with hypertrophic nonunion of tibia with shortening and deformity, attending out-patient department in NITOR. A total of 10 patients were included for evaluation from which 8 patients were selected using purposive sampling method. Surgery was with detailed preoperative x-ray analysis and measurement of magnitude of deformity and LLD. Other necessary investigations were done if clinically indicated and to prepare the patient for anesthesia. Statistical analysis of the results was obtained by using window-based computer software devised with Statistical Packages for Social Sciences (SPSS-22). Results: The mean age of patients was 32.62 years and the lowest and the highest ages were 14and 55 years respectively. Type of deformity out of 08 patients, 07 patients had only angulation deformity and 01 had angulation translation deformity. Distribution of patients with the Plane of deformity reflects that 2 patients had sagittal plane and 6 had oblique plane. Conclusion: As the outcome evaluation was done 5-11 months after operation, changes in outcome beyond 3-11 months like Knee, ankle arthritis and symptom status, recurrence of deformity, collapse of lengthen segment could not be ascertained.
