Abstract

Background: Schatzker type VI fractures of the proximal tibia are complex injuries often associated with extensive soft tissue damage. Effective management is critical to restoring limb function, preventing complications, and ensuring optimal recovery. The Ilizarov external fixator has been widely used in such cases due to its ability to provide stable fixation, allow early mobilization, and promote bone healing. A Aim: This study aimed to evaluate the functional outcomes of the Ilizarov external fixator in the management of Schatzker type VI fractures of the proximal tibia. Methods: A prospective study was conducted at Ayub Medical Hospital, Abbottabad, from December 2023 to February 2025. A total of 100 patients diagnosed with Schatzker type VI fractures of the proximal tibia were included. The Ilizarov external fixator was applied, and patients were assesse postoperatively for union time, range of motion, complications, and functional outcomes using the Knee Society Score (KSS) and Oxford Knee Score (OKS). Results: The mean fracture union time was 16.2 ± 3.4 weeks. Significant improvement in knee function was observed, with a mean KSS of 85.6±7.2 and a mean OKS of 40.3 ± 5.8 at the final follow-up. Complications included pin-site infections in 12% of cases, knee stiffness in 8%, and delayed union in 5%. Overall, 82% of patients reported good to excellent functional outcomes, while 14% had fair results, and 4% had poor outcomes. Conclusion: The Ilizarov external fixator proved to be an effective treatment for Schatzker type VI fractures of the proximal tibia, offering stable fixation, early weight-bearing, and satisfactory functional recovery. Despite some complications, the overall success rate was high, making it a viable option for managing these complex fractures.
