Abstract
Introduction
Tibiocalcaneal (TC) arthrodesis is a limb salvage method for patients with severe deformities combined with necrosis and/or luxation of the talus. The aim of this study was to examine the clinical and radiological outcome of TC arthrodesis.
Materials and methods
This retrospective study identified 12 patients with luxation and/or necrosis of the talus, due to charcot neuroarthropathy (83.3 %) or traumatic injuries (16.7 %). All patients underwent TC arthrodesis by an external fixator or nail arthrodesis. The mean follow up was 18 (6–36) months with a mean age of 51.3 (30–66) years. The data were collected using the AOFAS score as well as clinical and radiological examination during regular follow up.
Results
Seven (58.3 %) patients were treated with an external fixator, four (33.3 %) with nail arthrodesis and one (8.3 %) patient rejected both fixation methods. Four (100 %) patients achieved radiological and clinical bone union after nail arthrodesis and four (57.1 %) patients after external fixation. Three (42.9 %) patients treated by an external fixator showed a radiological moderate bone fusion, but a stable, asymptomatic non-union. One (8.3 %) case ended up in transfemoral amputation. Eleven patients (91.7 %) regained independent mobilization. The mean AOFAS score improved from 24.3 preoperatively to 66.7 postoperatively (p < 0.05). The postoperative satisfaction rate was good to excellent in 83.3 %.
Conclusion
TC arthrodesis is a promising and effective method for the treatment of severe ankle deformities with talus luxation. It allows patient’s return to mobility with good to excellent patient satisfaction.
