Iatrogenic hallux varus treatment algorithm.

Iatrogenic hallux varus is a relatively rare complication of corrective hallux valgus surgery that has multiple pathologic facets. It requires a comprehensive assessment that focuses on joint flexibility, joint integrity, soft tissue balance, and bony deformity. A step-wise treatment approach is used to address all elements of the deformity. The literature on hallux varus treatments consists mainly of retrospective case series, with several proposed procedures addressing various degrees of deformity. Comparison of these procedures is a challenging endeavor and each case should be considered on an individual basis.
