Mirror-image polydactyly is a rare congenital condition in which a person is born with extra fingers or toes on both sides of the body. The extra digits are usually symmetrical and mirror each other, hence the name. This condition is usually caused by a genetic mutation and is not usually associated with any other medical conditions.

The most common symptom of mirror-image polydactyly is the presence of extra fingers or toes on one side of the body. These extra digits may be fully formed or may be incompletely formed. Other symptoms may include webbing between the extra digits, a wide gap between the extra digits and the normal digits, and a curved shape to the extra digits.

Mirror-image polydactyly is a congenital condition caused by a genetic mutation. It is believed to be caused by a disruption in the development of the embryo, which results in the duplication of certain body parts. Other possible causes include environmental factors, such as exposure to certain chemicals or radiation, or a disruption in the mother's hormones during pregnancy.

The treatment for mirror-image polydactyly typically involves surgical removal of the extra digits. The surgery is usually done when the child is between 6 and 12 months old. The surgery is typically done under general anesthesia and involves removing the extra digits and then closing the wound with sutures. In some cases, the extra digits may be fused together and then removed as one piece. After the surgery, the child may need to wear a splint or cast for a few weeks to help protect the area and promote healing.

1. Family history of polydactyly
2. Maternal diabetes
3. Maternal use of certain medications during pregnancy
4. Maternal alcohol or tobacco use during pregnancy
5. Maternal exposure to certain environmental toxins during pregnancy
6. Genetic mutations or chromosomal abnormalities

At this time, there is no cure for mirror-image polydactyly. However, there are surgical options available to correct the extra digits. The surgery is typically done in infancy and is considered to be safe and effective. Additionally, there are medications available to help manage any pain or discomfort associated with the condition.
