Hallux valgus (HV) is defined as a lateral deviation of the great toe and medial deviation of the first metatarsal bone and might accompany with medial soft-tissue enlargement of the first metatarsal head (bunion). The causes of hallux valgus includes extrinsic and intrinsic factors. The extrinsic factors include wearing pointed and high-heeled shoes. And the intrinsic factors include structure change of foot, rheumatoid arthritis and gene et al.Pain and deformity are two major reasons that force patients with HV to visit doctors for medical intervention. Management of HV contains conservative and surgical interventions. The patients with juvenile hallux valgus seldom choose surgical intervention due to high recurrence unless the syndromes of HV seriously affect moving ability and the performance of activities of daily life. Although utilizing splint is often mentioned in conservative intervention of HV, there are few studies concerning with the benefits of the dynamic corrective splint. The purpose of this case report is to explore the clinical benefits of the new style dynamic corrective splint on reducing the deformity of moderate HV and its appropriateness.The precise findings of this study could be acquired from appearance picture, foot print and radiographic imaging of both feet. In this juvenile HV study, the improvement of HV is 9 to 11 degrees. The result indicates that the new style dynamic corrective splint can keep normal flexion and extension of the first metartasophalangeal joint and can provide continuing medial traction to prevent aggravation of HV. Also, the case and her parents are satisfied with this improvement. Our findings suggest that further studies have to be conducted such as the effects of the new style dynamic corrective splint and the clarification of the assessment criteria.
