Introduction: To date, arthrodesis and resection arthroplasty of the first MTP joint are major procedures for the hallux valgus in rheumatoid arthritis (RA) patients. Good clinical results of these procedures have been reported, however, arthrodesis or resection arthroplasty sacrificed the function of the first MTP joint. Recently, because of the introduction of biologics, RA can be well controlled and the function of joints can be preserved. We operate for hallux valgus in RA patients using Scarf osteotomy (joint-preserving surgery) and investigated clinical results of Scarf osteotomy for hallux valgus in RA patients. Methods: Between April 2011 and September 2013, a total of 44 RA patients (55 feet) who underwent Scarf osteotomy for hallux valgus were followed up for a mean duration of 28 months. All patients were available for follow-up for at least 2 years. X-rays of feet were taken pre and postoperatively at the final follow-up. The angle of the hallux valgus (HVA), M1M2 (M1M2A) and M1M5 (M1M5A) were examined. And the deviation of sesamoid bone was scored using Hardy�s classification. Results: The mean HVA were 48.7 degrees preoperatively and 14.1 degrees at final follow-up. The mean M1M2A were 13.8 degrees preoperatively and 8.8 degrees at final follow-up. The mean M1M5A were 32.4 degrees preoperatively and 22.0 degrees at final follow-up. The position of the sesamoid bone was improved in all cases at final follow-up using Hardy�s classification. Conclusions: Our results show that Scarf osteotomy is a beneficial procedure for hallux valgus in RA patients.
