Distraction Osteogenesis by Ring Fixator in Post Traumatic Tibial Bone Loss

Background: Reconstructing segmental bone loss defects presents a significant challenge within the field of orthopedics. The purpose of this study is to assess the clinical and radiological results of using the Ilizarov technique for tibia reconstruction following traumatic bone loss. Methods: This study was a prospective study involving 30 patients who experienced tibial bone loss in the diaphysis or metaphysis following trauma. These patients were treated with a ring fixator (Ilizarov) from March 2021 to February 2023. Unfortunately, five patients were lost to follow-up, leaving a cohort of 25 patients who were observed for a duration ranging from 9 to 12 months. Results: The current study involved 25 patients with post-traumatic tibial bone loss. The age range was 14 to 48 years, with a mean age of 28.4±8.8 years. Among the cases, 18 had a moderate defect (72%), which was significantly higher than those with a minor defect (20%) (P ≤ 0.05). Deformity was less than 7° in most cases (96%), while only one case had deformity greater than 7° (4%) (P ≤ 0.05(. Leg length discrepancy was less than 2.5 cm in the majority (96%), with only one case having a 3 cm length discrepancy (4%) (P ≤ 0.05). By the end of the follow-up period, all patients showed perfect union, enabling them to engage in daily activities post-operatively. Conclusion: The success of corticotomy and solid docking relies on well-vascularized bone and soft tissue. Soft tissue compromise at the corticotomy site can hinder healthy tissue regeneration.
