Purpose To develop and investigate the results of a new, simple and versatile method of tibia- calcaneal arthrodesis that reduces limb shortening. Materials and methods This prospective study was conducted in patients who voluntarily agreed to a new operation. Informed consent was obtained from all individual participants included in the study. For 17 years, we have observed 14 patients with various forms of osteomyelitis, fractures and septic necrosis of the talus, who underwent a new method of tibio-calcaneal-navicular arthrodesis (TCNA). The age of the patients ranged from 23 to 75 years, (42 years on average). 2 patients were female, 12 were male. The Ilizarov apparatus was used as a fixator. The average time of immobilization in the apparatus was 4.9 months (from 3.5 to 6 months). The operations were performed by one surgeon. Results In all patients the wounds healed by primary intention. The average limb shortening 1.9 ± 0.5 cm. AOFAS Ankle-Hindfoot score (n=14) in all patients came up to 77,9 ± 6,8 (min 68, max 86) SD 12,8. Patients wore ordinary footwear without arch supporter and heels till 2cm. Only two female patients over 70 years used a stick. 2 patients had minor pain during prolonged walking. Conclusion Excellent and good results were obtained in all patients. The new TCNA method allows restoring the support ability of a limb, reduces shortening and improves the quality of life for patients.
