Comparison between resection arthroplasty alone and resection arthroplasty with arthrodesis of the first MTP joint for rheumatoid forefoot deformities.
It has been reported that nearly 90% of patients with rheumatoid arthritis (RA) have problems with their feet. Several methods of treating hallux valgus deformity in RA have previously been reported, including arthrodesis and joint resection, and good results have been observed with surgical procedures. In this report, we 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. On clinical assessment, the American Orthopaedic Foot and Ankle Society (AOFAS) scale score significantly improved in both methods; however, the second method gave better results than the first method in relation to the footwear and alignment components. On radiographic assessment, in the first method there were no significant changes in the valgus angle (H-V angle) and the fifth metatarsal bone (M1/5) angle between preoperation and last follow-up. In contrast, these angles were decreased in the second method. One of the most important issues in the treatment of forefoot deformities in RA patients is to correct splaying foot deformity. We believe that the second method, which can correct splaying foot deformity, is currently the most reliable treatment method.
