[Triple arthrodesis of the foot after treated talar fracture--report of 3 cases].

Fracture of the talus, especially talar neck associated with talar dome necrosis, due to serious disorders of the ankle and subtalar joints. Disorders are so great that they often suggest to perform arthrodesis of the ankle joint. Disorders of subtalar joint are not so much visible on standard X-rays. Results of triple arthodesis performed in 3 patients (3 feet) because of talar fracture sequele were reported. In 1 femal talar fracture was combined with calcaneal fracture in the same foot. Age at trauma ranged from 22 do 31 years (mean 27). Indications for secondary operative treatment were mainly clinical criterias as subtalar pain and in 1 male additionaly varus deformity of the foot. Feet were stabilized by K wires going both through Chopart and ankle joints. Follow-up ranged from 35 to 50 months. Functional results in modyfied AOFAS scale ranged from 43 to 81 points (mean 65) of 94. Subjective results ranged from 7 to 10 points (mean 8) of 10. At follow-up examination no one reported restricted range of motion in the ankle joint in comparison to pre operation as well no any progression of osteoarthritis was visible on x-rays.
