Extra digit (Polydactyly) is usually a small piece of soft tissue; occasionally it may contain bone without joints; rarely it may be a complete, functioning digit. The extra digit is most common on the ulnar (little finger) side of the hand, less common on the radial (thumb) side, and very rarely within the middle three digits. The extra digit is most commonly an abnormal fork in an existing digit, or it may rarely originate at the wrist like a normal digit does.

Reasons for considering surgery

The goals of surgery are to improve the appearance of the hand and to prevent progressive deformity from developing as the child grows. Surgery is generally successful in both of these areas, largely correcting the appearance and social stigmata of congenitalism.

In many cases, surgery results in a greatly improved but not perfectly normal appearance, and in some situations a normal appearance can not be expected.

General Procedure

Extra digit correction is often more than simply removing the extra digits. The surgeon may also need to balance the tendons of the hand and stabilize the remaining finger joints so that the hand functions as normally as possible.

 Recovery

Home care is required, inspection of the incision to make sure that appropriate healing is taking place and to change the dressing.
