Tibiotalar arthrodesis: surgical method and effects on distal joints in 11 cases Volume 23, issue 1, Avril 2007


The aim of our work was to evaluate our tibiotalar arthrodesis technique and its effects on distal joints in treating ankle arthrosis secondary to a neglected injury or septic arthritis. From January 1996 to June 1999, we performed 26 tibiotalar arthrodeses. The inclusion criteria were arthrosis caused by a neglected injury or sequelae of osteoarthritis, a complete clinical and radiological evaluation, a normal subtalar joint, internal fixation by X cancellous bone screws and follow-up greater than six months. The series presented 11 cases (7 men and 4 women). The average age was 46. The average follow-up was 21 months (6 to 54 months). Using an anterior approach to the ankle, our arthrodesis technique consisted of joint surface resection and fixation by X cancellous bone screws. We maintained the ankle in neutral position. A plaster cast was applied for 12 weeks, with weight bearing allowed at week 10. Our patients were clinically evaluated according to the Duquennoy scoring system, the radiological determination of bone fusion and the appearance of the subtalar joint. The outcomes were good in 81.8% of the cases, with fusion in 9 cases obtained over on average period of 12.4 weeks. Two cases of pseudarthrodesis were observed. Posterior subtalar arthrosis occurred in 45.4% of the cases after an average of 12 months. Tibiotalar arthrodesis is a safe alternative for the treatment of neglected injuries and septic arthritis of the ankle after the occurrence of subtalar arthrosis in the long-term.
