INTRODUCTION: A major complication of arthrodesis is non-union in patients with Charcot arthropathy. This study examined the bone union in joints affected arthrodesis for Charcot arthropathy of the foot and ankle.
METHODS: The current retrospective study enrolled 15 patients (20 feet) who underwent arthrodesis (performed in 47 joints) for Charcot arthropathy from 2014 to 2020. Post-operative radiographs were classified based on the Brodsky anatomical classification system at 6 months, 1 year, and 2 years post-operatively. The association with pre-operative and intra-operative data was determined.
RESULTS: Bone union was achieved in 28 % of patients at 6 months, 57 % at 1 year, and 66 % at 2 years post-operatively. The bone union rates according to the Brodsky anatomic classification at 6 months, 1 year, and 2 years were 50 %, 67 %, and 67 % for type 1; 20 %, 44 %, and 56 % for type 2; and 36 %, 86 %, and 86 % for type 3A, respectively. At 1 year after arthrodesis surgery, the odds ratio for non-union in Brodsky type 2 compared to that in type 3A joints was 8.727 (95 % CI: 1.623-46.935, p = 0.006).
CONCLUSION: Arthrodesis procedures in joints affected by Charcot arthropathy, especially in Brodsky type 2 joints, should ensure perfect bone-to-bone fitting, good adaptation, sufficient bone grafting, and strong fixation.
