What is Syndactyly?
A congenital condition in which two or more fingers or toes are fused together, either by skin only (simple syndactyly) or by bone as well (complex syndactyly), caused by failure of the tissue between developing digits to fully separate during fetal development. Surgical separation is performed between 6 months and 2 years, particularly when adjacent digits of different lengths are involved (as between the ring and middle fingers), to prevent growth distortion.
Questions About Syndactyly
How do you pronounce syndactyly?
+
Syndactyly is pronounced sin-DAK-tih-lee. The stress falls on the second syllable, DAK, which rhymes with "back." Think of it as saying "sin" (like the word for wrongdoing), then "DACK" (hard k sound), then "tih-lee" to finish.
What's the most common mispronunciation of syndactyly?
+
Many people accidentally stress the first syllable and say SIN-dak-tih-lee, but that's incorrect. The correct stress is on the middle syllable: sin-DAK-tih-lee. Another common mistake is pronouncing the 'd' and 'c' separately, but they blend together into one "dack" sound.
How do you break syndactyly into syllables?
+
Syndactyly breaks into four syllables: syn-DAC-ty-ly. When you say it out loud, each syllable gets its own short sound, with DAC being the loudest part.
What do the word parts of syndactyly mean?
+
Syndactyly comes from two Greek roots: "syn-" meaning "together" and "dactyly" from "daktylos" meaning "finger" or "toe." So the word literally means "fingers or toes together," which describes exactly what the condition involves.
What's a simple way to explain what syndactyly means?
+
Syndactyly is a medical term for when two or more fingers or toes are fused or joined together. In everyday language, you might hear it called "webbed fingers" or "webbed toes," though that's a simplification of what doctors mean by the full term.
What are some related medical words that use the 'dactyly' root?
+
You might hear other medical terms using the "dactyly" root, such as polydactyly (having extra fingers or toes) and arachnodactyly (unusually long, slender fingers). All three words share the Greek root for fingers or toes.
Can you use syndactyly in a simple sentence?
+
Here's an example: "The doctor explained that her patient had syndactyly affecting two fingers on the left hand." Or: "Syndactyly is a condition present from birth in which digits grow fused together."
Is there a shorter way to write or say syndactyly?
+
Medical professionals sometimes shorten it to just "syndactyly" without an abbreviation, since the full word is already fairly concise. You won't typically see it shortened to initials like some other medical terms are.
