Sesamoid complex disruption as a cause of hallux valgus: report of three cases

Hallux valgus is perhaps the most common forefoot deformity, usually related to genetic factors, gender and footwear habits. The current cases represent an unusual etiology of the syndrome due to sesamoid ligamentary damage and inter-sesamoid ligament rupture. One of the cases was treated surgically by excision of the non-united lateral sesamoid and reconstruction of the intermetatarsal ligament. Another one was treated by a Wilson-like osteotomy. The third one was conservatively treated by casting. In these cases the hallux valgus angle declined following treatment.
