Correcting Severe Relapsed Hallux Varus Using Hexapod Circular External Fixator

Congenital hallux varus is an unusual condition in which the big toe is medially angulated at the metatarsophalangeal joint. Different surgical methods have been described to correct it; however, there is always a risk of recurrence. The multiplanar nature of the deformity and the disrupted anatomy from a previous surgery make recurrent cases difficult to treat. A 16-year-old adolescent boy presented with a recurrent hallux varus deformity after a previous surgical correction. This case report describes its successful treatment using a hexapod circular external fixator as a salvage procedure.
