Newborn baby has an extra thumb

A newborn baby with an extra thumb is a common congenital deformity, which is mainly manifested as six fingers. If it is not corrected and removed in advance, the extra fingers will cause a lot of inconvenience to the baby when he grows up, and it will be more difficult to correct when he grows up. Therefore, if you find that your baby has six fingers, you must perform surgery as soon as possible. Since the baby has a strong recovery ability, the wound can recover in a short time. Let's take a look at how to deal with a newborn baby with an extra thumb?

Six fingers are one of the most common congenital hand deformities among Chinese people. It is most common when the fingers grow next to the thumb. It is a genetically related disease. This condition is a developmental malformation and is generally not hereditary, and can be corrected with surgery.

Hexadactyly is a sex-chromosome dominant genetic disease. The disease-causing gene is located on the X chromosome. If the patient is a male, the probability of his offspring with a normal female getting the disease is 50% (the boy is normal and the girl is a hexadactyly patient). If the patient is a female, there are two types of phenotypes: complete dominance and incomplete dominance. The probability of children born to a complete dominant patient getting the disease is 100%, and the probability of children born to an incomplete dominant patient with a normal male is 50% (boys and girls have the same probability of getting the disease). Most of them are corrected by surgery after the age of 3. If it is corrected too early, it may damage the epiphysis and cause displacement, affecting joint movement, lateral instability and small fingertips. No other testing is required.

This is polydactyly. The exact cause is unknown. The disease may be related to environmental factors and has little to do with genetic factors, so the chance of it being passed on to offspring is very small. Generally, surgical treatment is performed after 6-12 months. Before the operation, the child will be evaluated to see if they have other malformations, and heart and abdominal ultrasound, chest X-ray, blood tests, etc. will be performed.

Six fingers is a common deformity that can be corrected through surgery. The earlier the correction, the faster the recovery. It is recommended to go to the orthopedics department of a tertiary hospital at or above the municipal level for further consultation. The operation is relatively simple. At the same time, do relevant examinations under the guidance of the doctor, so please don't worry too much.
