Overview
Central polydactyly of toes is a rare congenital condition where a person is born with one or more extra toes in the middle part of the foot, typically involving the second, third, or fourth toes. This is different from having an extra toe on the outer edge (postaxial polydactyly) or on the inner edge near the big toe (preaxial polydactyly). The extra toe may be fully formed with its own bones, joints, and nail, or it may be a smaller, less developed digit. This condition is present at birth and is usually noticed right away. It is important to note that this specific Orphanet classification (295010) is labeled as 'OBSOLETE,' meaning it has been retired or merged into a broader or updated classification of polydactyly. Patients with this condition may now be classified under more general polydactyly categories. Central polydactyly of toes can occur on its own (isolated) or as part of a broader genetic syndrome. When it occurs in isolation, it is primarily a structural issue and does not typically affect overall health. Treatment usually involves surgical removal of the extra toe to improve foot function, shoe fitting, and appearance. The timing of surgery is often planned during early childhood. Outcomes after surgery are generally very good, and most children go on to walk and run normally.
