Ectrodactyly[edit]
Introduction[edit]
Ectrodactyly, also known as split hand/split foot malformation (SHFM), is a rare congenital disorder. This condition is characterized by the absence of one or more central digits of the hands and feet.
Classification[edit]
Ectrodactyly is categorized into several types based on its phenotypic manifestations and genetic causes.
Types[edit]
- Type 1: Simple Ectrodactyly
- Type 2: Ectrodactyly associated with other limb anomalies
- Type 3: Ectrodactyly associated with syndromes
Causes[edit]
Ectrodactyly is caused by genetic mutations. It can be inherited in an autosomal dominant pattern or can occur due to new mutations.
Diagnosis[edit]
Diagnosis is often made through physical examination and imaging techniques like X-rays. Genetic testing can confirm the diagnosis.
Treatment[edit]
Treatment options include surgical reconstruction and the use of prosthetics to improve function and appearance.
Epidemiology[edit]
Ectrodactyly affects approximately 1 in 90,000 live births worldwide.
Society and Culture[edit]
See Also[edit]
