Syndactyly type 5 is a rare form of syndactyly, a congenital condition in which two or more digits are fused together. It is characterized by the fusion of the fourth and fifth digits of the hand or foot. This type of syndactyly is usually associated with other congenital anomalies, such as polydactyly, and is often seen in patients with genetic syndromes.

The symptoms of Syndactyly type 5 include webbing of the fingers and toes, fusion of the fingers and toes, and the presence of extra digits. Other symptoms may include abnormal nail formation, abnormal skin creases, and abnormal joint movement.

Syndactyly type 5 is a rare congenital condition caused by a genetic mutation. It is believed to be caused by a mutation in the HOXD13 gene, which is responsible for the development of the hands and feet. Other possible causes include environmental factors, such as exposure to certain chemicals or radiation, or a combination of genetic and environmental factors.

1. Surgery: Surgery is the most common treatment for syndactyly type 5. The goal of surgery is to separate the fused digits and create a more normal appearance. The surgery is usually done under general anesthesia and can involve skin grafts, tissue expansion, and tendon transfers.

2. Splinting: Splinting is another treatment option for syndactyly type 5. Splints can be used to help separate the fused digits and improve the range of motion.

3. Physical Therapy: Physical therapy can help improve range of motion and strength in the affected digits.

4. Occupational Therapy: Occupational therapy can help improve the function of the affected digits and help the patient adapt to any changes in their daily activities.

1. Family history of syndactyly
2. Maternal diabetes
3. Maternal use of certain medications during pregnancy
4. Maternal alcohol or drug 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 Syndactyly type 5. However, there are surgical options available to separate the fused digits. Medications are not typically used to treat Syndactyly type 5.
