RESUMO
BACKGROUND: Hindfoot arthrodesis is used in patients with advanced-stage acquired flatfoot, usually associated with degenerative joint disease. The objective of the present study was to evaluate the clinical and radiographic results of hindfoot arthrodesis using the single-incision medial approach. METHODS: A case series of 18 consecutive patients undergoing surgical correction between 2015 and 2018 with hindfoot arthrodesis using the medial approach was evaluated. The clinical assessment used the visual analog pain scale, AOFAS hindfoot score, SF-36, and foot function index. Radiographs and personal satisfaction criteria were also analyzed. RESULTS: All radiographic parameters evaluated showed a significant improvement (p < .05), except the calcaneal pitch. Pain decreased by 5.1 points (p < .001), and the mean final AOFAS score was 72.6. In three feet, a new surgery was required. Two feet developed talar necrosis. None of the cases presented surgical wound dehiscence, and two presented with superficial infection, which was resolved with the use of oral antibiotics. CONCLUSION: Double arthrodesis (subtalar and talonavicular) to correct adult-acquired valgus flatfoot using a medial approach has a low risk of soft tissue complications and presents satisfactory functional results. Avascular necrosis is a serious complication that was present in 11% of cases.

BACKGROUND: Bunionette is a common foot disorder, and several types of corrective surgery have been described. With the popularization of minimally invasive surgeries, the forefoot region has become a suitable area for this type of technique. The aim of this study was to evaluate the results of oblique distal osteotomy of the fifth metatarsal adapted for a percutaneous approach. METHODS: We prospectively evaluated 31 consecutive tailor's bunion patients who underwent operative correction on a total of 42 feet between 2017 and 2019 after failure of conservative treatment. Clinical outcomes such as pain (visual analog scale [VAS]), function (American Orthopaedic Foot & Ankle Society [AOFAS] Lesser Toe Metatarsophalangeal-Interphalangeal Scale scoring system), personal satisfaction, and complications were evaluated. Radiographic aspects were also examined. Shapiro and Mann-Whitney statistical tests were conducted. The average age of the patients was 69.5 years, and the average follow-up was 13.1 months. RESULTS: After the operative procedure, there was a decrease of 6.6 points on the VAS for pain (P < .001) and an increase of 34.9 in the AOFAS score (P < .001). Radiographic correction was achieved for both the fifth metatarsophalangeal angle (P < .001) and the intermetatarsal angle (P < .001), which showed decreased values. There was 1 case of superficial infection and 2 cases of nonunion (asymptomatic). A large majority of patients regarded the procedure outcome as satisfactory. CONCLUSION: This percutaneous oblique distal osteotomy of the fifth metatarsal for bunionette deformity produced improvements in pain and function and a high rate of satisfaction, with a low incidence of complications and a high capacity for correcting the deformity. LEVEL OF EVIDENCE: Level II, prospective cohort study.
