Preaxial polydactyly is a condition where a person is born with extra fingers or toes on the thumb or big toe side of their hands or feet. In this article, we’ll explore what preaxial polydactyly is, its types, causes, symptoms, diagnostic tests, treatments, and related medications, all explained in simple, easy-to-understand language.
Types of Preaxial Polydactyly:
- Type I: Extra digit(s) with a small, soft bump.
- Type II: Extra digit(s) attached by skin and bones.
- Type III: Extra digit(s) fully formed with separate bones.
Causes of Preaxial Polydactyly
- Genetics: Often runs in families due to inherited genes.
- Environmental Factors: Exposure to certain substances during pregnancy.
- Teratogens: Harmful substances causing abnormal fetal development.
