{Reference Type}: Case Reports {Title}: Triple osteotomy for erosive first metatarsal in a patient with rheumatoid arthritis: a case report. {Author}: Tobimatsu H;Ikari K;Yano K;Okazaki K; {Journal}: Mod Rheumatol Case Rep {Volume}: 5 {Issue}: 1 {Year}: 01 2021 暂无{DOI}: 10.1080/24725625.2020.1789303 {Abstract}: Recently, over the half of the patients with rheumatoid arthritis achieved clinical remission with beneficial effects of disease modifying anti-rheumatic drugs, including biological disease modifying anti-rheumatic drugs. Because the patients in remission should have no/reduced progression of joint damage, there is a trend towards joint-preserving surgery in the treatment of rheumatoid forefoot deformities. Here we report a 76-year-old woman with rheumatoid arthritis developed a severe forefoot deformity including a large bony erosion of the first metatarsal head. She showed near remission for rheumatoid arthritis without having clinically active synovitis in her MTP joints. To preserving her metatarsophalangeal joint, a double first metatarsal osteotomy was planned to remove the bony erosion and simultaneously correct the hallux valgus. Thirty-month follow-up demonstrated excellent radiographical and patient-reported outcomes. To the best of our knowledge, this is the first case of a double first metatarsal osteotomy to remove the bony erosion and simultaneously correct the hallux valgus in a patient with rheumatoid arthritis with a large erosion of the first metatarsal head.
