Ectrodactyly is a medical condition characterized by the absence or malformation of one or more fingers or toes. It is also known as "lobster claw syndrome". The word "ectrodactyly" is spelled with four syllables: /ɛk.trə.dæk.tɪl.i/. The initial "e" is pronounced as "eh", the "o" is silent and the "y" at the end is pronounced as "ee". The root of the word, "dactyl", meaning finger or toe, is derived from the Greek language. The spelling of this word shows similarities to the pronunciation, however, the sounds must be memorized.
Ectrodactyly is a rare congenital malformation characterized by the absence or malformation of one or more fingers or toes. Also known as split hand/foot malformation, it is a genetic disorder that affects the development of the limbs during fetal development.
In individuals with ectrodactyly, the hand or foot appears cleft-like, with a deep separation or absence of central digits. This results in a distinct appearance known as "lobster claw" deformity, as the hand or foot may resemble the claws of a lobster. The condition can affect one or both hands and/or feet and may vary in severity.
Ectrodactyly is caused by mutations in certain genes involved in limb development, disrupting the signals that regulate the formation of fingers or toes. It can occur sporadically or be inherited in an autosomal dominant or autosomal recessive manner, depending on the specific genetic mutation.
While ectrodactyly is primarily a physical anomaly, it may be associated with other abnormalities or syndromes like Ectrodactyly-Ectodermal Dysplasia-Clefting Syndrome (EEC syndrome). Treatment for ectrodactyly involves supportive care, including surgery to improve the function and appearance of the affected limb. Prosthetic devices or orthopedic interventions may be used to enhance mobility and grip strength.
Overall, ectrodactyly is a congenital condition characterized by the absence or malformation of fingers or toes, requiring medical intervention and support to optimize limb function and reduce functional limitations.
The word "ectrodactyly" is derived from two Greek roots: "ek" (meaning "out" or "away") and "daktylos" (meaning "finger" or "toe"). Therefore, "ectrodactyly" literally translates to "out or away from the fingers or toes". It is a term used in medicine to describe a congenital condition characterized by the absence or malformation of fingers or toes.
