Background: The purpose of this study was to clarify the 2-year clinical and radiological outcomes of nonoperative treatment using foot orthosis for hallux valgus patients. Methods: Patients who underwent nonoperative treatment using foot orthosis were surveyed prospectively. Foot orthoses were made by one certified orthotist using the standardized method. Pain and quality of life were evaluated using subjective and objective assessment measures at 3, 6, 12, 18, and 24 months. Furthermore, radiological outcomes, patient satisfaction, and adherence to treatment were surveyed. Results: A total of 53 patients (50 women and 3 men; median age, 63 years) were included for analysis. The pain visual analogue scale score significantly decreased over time, with the lowest score observed at 12 months. The treatment effect was maintained over 24 months (median score, 52, 21, and 27 points at baseline, 12 months, and 24 months, respectively; P < .001). The Japanese Society for Surgery of the Foot hallux scale, American Academy of Orthopaedic Surgeons Foot and Ankle Scale, and 36-Item Short-Form Health Survey bodily pain subscale also improved, although the treatment effects were maximal at 6 months and decreased thereafter. At 24 months, 43 (81%) patients continued to use the orthosis, with the median visual analogue scale score for patient satisfaction of 76 points. The hallux valgus angle and intermetatarsal angle did not change during the 24-month period. Conclusion: Nonoperative treatment using foot orthoses decreased pain in patients with hallux valgus. The effect of treatment was maintained up to 2 years with a relatively high degree of patient satisfaction. However, treating physicians should inform patients to set realistic expectations and be aware that a limited degree of pain reduction is expected.
