Ilizarov Ankle Arthrodesis: A Simple Salvage Solution for Failed and Neglected Ankle Fractures

Background Infection around the ankle joint after fracture fixation, or septic arthritis with active discharging sinuses is often challenging to manage with conventional procedures of arthrodesis. The Ilizarov method of arthrodesis gives a better alternative for salvage in such cases. Methods This was a retrospective study including 20 patients who were subjected to tibiotalar arthrodesis with Ilizarov method. The major pathologies included internal fixation of ankle fractures complicated by infection, posttraumatic infected ankle arthritis, and osteomyelitis. The patients were evaluated on the basis of Association for the Study and Application of the Method of Ilizarov (ASAMI) criteria. The aim of the surgery was to achieve plantigrade, stable, and painless foot with no signs of infection. Results A total of 20 patients were operated and reviewed at our institute. The study comprised of 15 male and 5 female patients with a mean age of 43.9 years (range 33-55 years). Out of 20 patients, 4 patients had complications of pin-tract infection and one had wire breakage of the forefoot ring. According to the ASAMI criteria, 17 patients had excellent bone scores and 18 patients had good functional scores. Union was achieved in all patients with resolution of infection and the mean limb length discrepancy was 1.92 cm (range 1-2.5 cm). Conclusions The Ilizarov fixator for ankle arthrodesis provides an excellent way for strong bone fusion, infection eradication, early weight-bearing, and the added benefits of compression at the arthrodesis site post-operatively.
