Summary
Brief summary
Hallux valgus presents with pain and a progressive valgus deformity of the first ray. The newly designed silicone toe separators fabricated by 3D printing technology are used for 12-week treatment. The pain score and foot function index (FFI) are rated, and hallux valgus angle are measured before and after intervention to investigate the treatment effectiveness.
