However, removing the extra "inside" digit does not narrow the foot in any way and reconstruction of the middle of the foot in a cosmetically acceptable fashion can be very difficult. In patients that exhibit central polydactyly where the extra digit is in the middle of the foot, it becomes more difficult to determine which digit to surgically remove. In instances where you have a polydactyly (extra digit), if it occurs on the medial or lateral side of the foot, then amputation of the extra digit is the treatment of choice, assuming once again the extra digit does not share a common blood supply with the adjacent digit. If the two adjacent bones are fused separation becomes more difficult because many times there is only a single tendon and vascular system supplying the two toes and once separated obviously the two toes would no longer be able to share the tendon and blood supply.
Partially webbed toes skin#
Simple syndactaly involves skin grafts to separate the toes. Perhaps the number one reason for surgical intervention is cosmetic disapproval by the patient, rather than loss of function, at least in the foot. Surgical intervention for simple syndactaly of the foot is rarely indicated as the webbing causes minimal loss of function of the toes, it is more of an issue with the fingers. Type 3, associated with metatarsal fusion. Type 2 (synpolydactyly), syndactyly of the lateral two toes and polydactaly of the fifth toe in the syndactyly web. Type 1 (zygodactyly), partial or complete webbing of the second and third toes hands may also be affected. In the foot three types of webbing are seen.
The "location" of the extra digit goes a long way in determining treatment, if treatment is necessary. "Polysyndactyly" describes both webbing and the presence of an extra number of fingers or toes. Bilateral involvement is found in 50% of patients. The web connections usually run up to the first joint of the finger or toe, but may run the entire length. In fact webbing of the toes may be associated with over 300 syndromes. Syndactyly can also occur along with other birth defects involving the skull, face, and bones. This form is often inherited and is not unusual. In its most common form, it is seen as webbing between the 2nd and 3rd toes. Webbing may be discovered during an examination of an infant or child. Webbing occurs once in every 2000-2500 births and is three times more common in males than females. What occurs here is a failure of two or more adjacent digits to fully segmentalize during development. Webbing usually only involves a skin connection between the two areas, but in rare cases may involve the fusion of bones. It refers to the connection of two or more fingers or toes.
Webbing of the fingers and toes is called syndactaly.
