Bilateral tibial hallux sesamoid agenesis and fibular hallux sesamoid hypoplasia in a patient with bilateral hallux valgus.

We report the clinical features, radiographic findings, management, and results of a patient with bilateral hallux valgus and associated bilateral tibial hallux sesamoid agenesis and fibular hallux sesamoid hypoplasia. Our patient was managed operatively with good clinical results. Combined tibial sesamoid agenesis and fibular sesamoid hypoplasia do not seem to negatively influence the management of hallux valgus.
