Torikai E et al. - In this report, the authors compare the clinical and radiological outcomes of resection arthroplasty alone (the first method) and resection arthroplasty with arthrodesis of the first MTP joint (the second method) for the treatment of forefoot deformities of RA patients. One of the most important issues in the treatment of forefoot deformities in RA patients is to correct splaying foot deformity. The authors believe that the second method, which can correct splaying foot deformity, is currently the most reliable treatment method.
