Clinical Efficacy of the Ilizarov Technique in the Treatment of Infected Non Union And Bone Defects Results of at least 2 Years of Follow-up.

Background: Surgical technique and preliminary clinical results using the Ilizarov Technique in the Treatment of Infected Non Union and Bone Defects. In order to address the issues related to non-union, including bone gap, bone defect and infection an Ilizarov external fixator was used. In order to achieve nonunion, bone defects and repair the limb length difference, stable fixation, corticotomy, and bone transfer were used to decrease or eradicate infection. Methods: Clinical data were collected on patients with infected bone defects and bone shortening deformities treated with Ilizarov bone transfer technology at Wuhan University Zhongnan Hospital from January 2021 to December 2023. The clinical data of 24 cases 16 males and 8 females with bone defect treated by Ilizarov bone transport were analyzed prospective observational research. The results were analyzed using the ASAMI scoring system. Results: Out of 24 Patient the results of skeletal outcomes 14 cases had Excellent,7cases result good 3 cases had moderate results. In terms of functional outcome. The results of 10 patients had an outstanding performance, 8 patients had a good performance, 4 patients had average performance and 2 patients had poor performance. The average fixed period was 11.16 months (min 8 months, max 14 months). The average length of regrowth is 5.67 cm (min 3.98cm, max 6.97cm). The survey found that the average elongation index was 1.94 months/cm. Conclusion: The Ilizarov bone transfer technique can achieve satisfactory results in the treatment of infected Nonunion and bone defects. Ilizarov bone transfer technique can safely and effectively shorten bone healing time, improve the healing index, and significantly improve a patient’s quality of life.
