Abstract
Purpose
Arthrodesis of the ankle joint is an accepted treatment option in patients with end-stage ankle arthritis. The goal is to achieve fusion between the tibia and the talus, thereby stabilizing the joint and alleviating pain. There might be associated limb length discrepancy, especially in post-traumatic and post-infectious cases. These patients require limb lengthening and arthrodesis. The purpose of this study is to report our experience with simultaneous ankle arthrodesis and lengthening using external fixation in adolescent and young adult patients.
Methods
This retrospective case series included all patients treated in our hospital by concomitant ankle arthrodesis and tibial lengthening procedures on the same limb, using ring external fixation system. All surgeries included distal tibial joint surface resection and the talar dome, thereby correcting any associated deformity at the ankle. The arthrodesis was fixed and compressed using ring external fixator. A concurrent proximal tibial osteotomy was done, and limb lengthening, or bone transport was performed.
Results
Eight patients operated between the years 2012–2020 were included in this study. Median patient age was 20.4 years (range 4–62 years), 50% women. Median limb lengthening was 20 mm (range 10–55 mm), and median final leg length discrepancy (LLD) was 7.5 mm (range 1–72 mm). The most common complication recorded was pin tract infection, which resolved with empiric antibiotics in all cases.
Conclusion
Based on our experience, combined arthrodesis and proximal tibial lengthening is efficient solution that provides stable ankle and restores length of the tibia even in complex and challenging situations.
