Oligodactyly

Oligodactyly is a medical condition characterized by fewer than five fingers or toes on a hand or foot. This condition can occur as an isolated anomaly or as part of a syndrome. The term is derived from the Greek words oligos meaning "few" and daktylos meaning "finger".

Causes[edit | edit source]

The exact cause of oligodactyly is not known. However, it is believed to be caused by a combination of genetic and environmental factors. Some cases have been linked to mutations in specific genes, such as the SHH, GLI3, and HOXD13. These genes are involved in the development of limbs during embryonic growth.

Types[edit | edit source]

There are two main types of oligodactyly: postaxial and preaxial. In postaxial oligodactyly, the outermost digit (the little finger or toe) is missing. In preaxial oligodactyly, the innermost digit (the thumb or big toe) is missing.

Diagnosis[edit | edit source]

Oligodactyly can be diagnosed through a physical examination and imaging tests such as x-rays. Genetic testing may also be performed to identify any genetic mutations associated with the condition.

Treatment[edit | edit source]

The treatment for oligodactyly depends on the severity of the condition and the specific needs of the individual. Treatment options may include physical therapy, occupational therapy, and in some cases, surgery. The goal of treatment is to improve function and appearance.
