Addressing misperceptions about the ‘positive round sign’ and hallux valgus recurrence

Okuda and colleagues first described the “positive round sign,” which has become a primary indication for “frontal plane correction” of hallux abducto valgus deformity (HAV). The authors observed that patients with HAV deformity had a rounded appearance of the lateral edge of the first metatarsal on a dorsoplantar radiograph in comparison to healthy (non-HAV) control patients.
