Hallux Flexus: Sequela of Residual Clubfoot

Peter Andrew Crisologo, Darren M Woodruff and Erik K Monson

A dorsal bunion, also known as hallux flexus, is a deformity where the 1st metatarsal is in a dorsiflexed position and the proximal phalanx of the hallux is in a plantarflexed position usually articulating with the plantar aspect of the 1st metatarsal head. Multiple etiologies exist for this condition; the one most evaluated has been the occurrence of hallux flexus following clubfoot surgery. The following is a case report on a patient that is skeletally mature and developed hallux flexus following soft tissue correction of a clubfoot. This deformity was surgically corrected with an arthrodesis of the 1st metatarsal phalangeal joint (MTPJ). The patient was followed for 3 years following surgery and has returned to all activities. This case report illustrates that an arthrodesis of the 1st MTPJ can be performed as a corrective procedure of hallux flexus.
