Nonsurgical treatment for hallux abducto valgus with botulinum toxin A.

Hallux abducto valgus is a frequently seen abnormality of the first metatarsophalangeal joint. Limited conservative treatment options exist, making surgery the only definitive treatment option for a mild-to-moderate deformity. A problem arises if the patient is not a surgical candidate owing to comorbidities, noncompliance, or personal reasons, such as work or family obligations. We describe a case in which the use of botulinum toxin A injection reduced not only the hallux abducto valgus deformity clinically and radiographically but also its associated pain.
