| Summary: | Category: Hindfoot Introduction/Purpose: Hindfoot arthrodesis is used in patients with flat feet acquired in advanced stages, usually associated with degenerative joint disease. The objective of the study is to evaluate the clinical and radiographic results of hindfoot arthrodesis using the medial approach. Methods: A prospective cohort of 23 consecutive patients who underwent surgical correction between the years 2012 and 2018 through the hindfoot modeling arthrodesis was evaluated. Clinical assessment was performed using the visual analogue pain scale (VAS), AOFAS score for the hindfoot, SF-36 and FFI (Foot Function Index). Radiographic images were also analyzed, as well as satisfaction criteria. Results: In six procedures, calcanecuboid arthrodesis was included, with a small lateral access route. The average pain score decreased by 6.04 points (p <0.001), with an average final AOFAS of 75.63. Two cases presented talus necrosis, in three there was no consolidation of talonavicular arthrodesis, and in three others, synthesis material was removed. No case presented wound dehiscence and only one needed to treat superficial infection with antibiotics. Conclusion: Arthrodesis to correct adult acquired valgus flat feet can be performed using the medial approach with good clinical results and low rates of healing complications. However, about 25% of the patients had other complications that led to the need for a surgical approach.
