    Abstract:
    We investigated the midterm results of resection arthroplasty of all 5 metatarsal heads in patients with rheumatoid arthritis and forefoot deformity and analyzed the factors that affect patient satisfaction levels. Of 64 patients (1 male, 63 females), 107 feet were treated with resection arthroplasty for forefoot deformity at our hospital from January 1992 to December 2005. The mean follow-up period was 5.8 ± 3.1 years, with all patients having at least 1 year of follow-up. Of the 64 patients, 75% were satisfied with the surgery. The mean score for the postoperative Japanese Society for Surgery of the Foot lesser metatarsophalangeal-interphalangeal scale was 75.0 ± 15.8 points. Multivariate logistic regression analysis showed that patient-reported dissatisfaction was significantly associated with the recurrence of hammer toe deformity (odds ratio 2.66, 95% confidence interval 1.07 to 6.97), shortening of the resection arthroplasty space (odds ratio 0.85 for a 1-unit increase, 95% confidence interval 0.74 to 0.96), and the recurrence of hallux valgus (odds ratio 1.04 for a 1-unit increase, 95% confidence interval 1.00 to 1.09) during the postoperative period. From our results, interventions to prevent recurrence of hammer toe deformity, especially in toes with preoperative metatarsophalangeal joint dislocations, have been shown to be important in preventing complications and patient dissatisfaction after resection arthroplasty.
