Congenital Third Foot Deformity: A Case Report

A congenital accessory limb is a rare condition that may be associated with predisposing factors such as drug or alcohol or toxin exposure, trauma, and deformities such as spina bifida. This article describes a case involving an accessory foot in an otherwise healthy 33-year-old male. It is likely that the etiology of this case was an early embryologic exposure to amniotic constriction bands that affected the development of the distal limb. Level of Clinical Evidence: 4
