1, Methods From 1988, 56 cases of congenital thumb polydactyly, trigger thumb and macrodactyly were treated surgically.

2, Research shows that polydactyly has a similar development mechanism, and this kind of polydactyly character seems to be controlled by homologous genes among species.

3, Conclusions: These findings show that central polydactyly , syndactyly, and central deficiencies have the same early morphological changes: abnormal clefts in the central part of the footplate.

4, To study the genes of polydactyly and molecular mechanism can help us to know how limbs form and reveal the producing process of limbs.

5, Mostly people go for plastic surgery. And sometimes when polydactyly is minimal, it can be cured normally, without an operation.

6, Doctors attending to the child said that it was a rare phenomenon and diagnosed it as polydactyly.

7, She said that, it is absolutely curable. Mostly people go for plastic surgery. And sometimes when polydactyly is minimal, it can be cured normally, without an operation.

8, His major systemic findings include cleft lip and palate, polydactyly , simian crease, congenital heart disease (V. S. D. ), inguinal hernia, hypotonicity of neck and low set ear.
