title: Hallux valgus deformity associated with bilateral absence of the tibial and fibular hallucal sesamoids.
abstract: The absence of both tibial and fibular hallucal sesamoids is an extremely rare condition. It can present as hallux valgus, hallux varus, or metatarsalgia. It can result from primary mesenchymal differentiation failure or an ossification problem. Preoperative magnetic resonance imaging can help to differentiate the problem and assist preoperative planning in the case of surgical correction of the associated hallux valgus deformity.
