Syndactyly is a hand deformity where two or more fingers (or toes) are fused together. Polydactyly is a condition where the hand (or foot) has additional fingers/toes (most often the little finger/toe). These two conditions are the most common hand and foot conditions seen by pediatric plastic surgeons. While some can be treated non surgically, most require surgical treatment.
Polydactyly ranges from an extra piece of soft tissue (skin) that has no bone inside to a complete duplication of a finger or toe.
There are different levels of duplication depending which bone in the thumb is split. The thumb may have 3 bones instead of two, this is called a triphalangeal thumb.
Occasionally occurs with syndactyly (webbed/fused fingers).
Duplication more common in the ring finger, then the long finger, then the index finger (which is rarely duplicated) Central duplication often occurs on both hands and often occurs in conjunction with syndactyly Many patients have polydactyly or syndactyly involving the feet as well
Surgical options exist for each type of polydactyly. A functional hand assessment by an occupational therapist, X-rays and consultation with a plastic surgeon Dr. Rahul Goyal is required to determine the best possible option for your child.
