Tibiocalcameal arthrodesis as a surgical option for Charcot ankle deformity

Abstract

Object. To assess the effectivity and safety of different tibiocalcaneal arthrodesis types in treatment of patients with Charcot ankle deformity depending on disease severity. Materials and methods. We have analyzed the outcomes after treatment of 16 patients with diabetic neuropathic ankle arthropathy (Charcot ankle) at the stage of septic complications in bones of ankle and subtalar joints. The observation period was more than 1 [1–3] year. Ilizarov fixator for TCA was used in 8 cases; internal fixation with cannulated screws was applied in 8 cases.Results. In the early periods (up to 1 month from the operation) no complications were revealed. Complications in later terms developed in 4 patients: three with internal fixation and one with external.Conclusion. In our opinion, when choosing foot fixation tactics for heel-tibial arthrodesis, risk groups should be considered stage D according to Rogers classification and stage 3 according to Wagner classification, and after resection of bones in these patients external fixation is preferable. In the remaining stages, internal fixation is advisable because of the patient's higher quality of life and shortening of the rehabilitation period.
