Syndactyly can be divided into two types zygosyndactyly and polysyndactyly. Zygosyndactyly consists of complete or incomplete webbing between the toes usually the second or third. It is rarely symptomatic and rarely requires treatment. In polysyndactyly there is often duplication of the fifth toe with webbing between it and the original toe. Surgery may be indicated to amputate the duplicated toe to narrow the foot.
