Methods: The operators used one of two treatment strategies: neutral fixation without compression or continued compression. The following were assessed: rates of union, ASAMI bone scores, ASAMI functional scores, treatment time, complications, duration of hospital stay. It is prospective study of treatment of aseptic nonunion of shaft tibia. As we have taken 35 patients of tibial nonunion. All relevant pre and perioperative information and complications were recorded. Also assessment of functional outcome was made.

Results: We also analyzed the differences in time to union in the subgroup of patients with at least one risk factor for disturbances in fracture healing. The following risk factors were considered: diabetes mellitus, corticosteroid therapy, smoking, advanced lower extremity vascular disease, and alcohol dependence. Sample size in our study was of 32 out of 35 cases has united, about 91% success rate. The average duration of nonunion was about 14.5 months, average union time (fixator removal) is about 6.2 months. Two of our patient were showing poor tolerance to ilizarov external fixator changed to other modality.

Conclusion: The Ilizarov method offers a greater extent of correction in posttraumatic deformities and helps better correct posttraumatic limb shortening in comparison to the results achieved with internal osteosynthesis methods. Therefore Ilizarov technique is very helpful in treating nonunion of long bones and has advantage of early wt. Bearing, movements of nearby joints encouraged which reduces edema and joint stiffness.
