Polydactyly is a condition where a person is born with more fingers or toes than the typical number. Hyperdactylies specifically focuses on cases where there is an exaggerated surplus of digits. This abnormality can manifest itself in various ways, such as having more than five fingers or toes on a single extremity, or possessing additional digits that lack full functionality. The additional digits may be fully formed, partially formed, or rudimentary, and their location can vary, although they are mainly observed on the hands or feet.
Hyperdactylies can occur as an isolated abnormality, without any underlying medical condition, or as part of a larger syndrome that affects other parts of the body. It can be inherited or result from spontaneous genetic mutations during fetal development. While the presence of extra digits generally does not cause major functional impairment, surgical intervention may be considered for cosmetic reasons or if the extra digits cause significant physical limitations.
In conclusion, hyperdactylies is a rare congenital condition characterized by the presence of excessive additional fingers or toes. It is known as polydactyly, which refers to any extra digits. This condition can occur in isolation or alongside other syndromes, and it can be surgically treated based on individual circumstances.
