How to Pronounce Sesamoiditis

Say it like this: ses-ah-moyd-EYE-tis. Break it into four syllables, and put the strongest emphasis on the third syllable (EYE). The first part rhymes with "mess," the second part sounds like "uh," the third part sounds like "void" with an EYE sound, and the last part sounds like "tis."

Stress the third syllable: ses-ah-moyd-EYE-tis. A common mistake is putting the stress on the second syllable (ses-AH-moyd-eye-tis), which sounds wrong. Remember: the emphasis goes on EYE.

The word has two main parts: "sesamoid" (the name of small bones in your foot) and "-itis" (a suffix meaning inflammation). So sesamoiditis literally means "inflammation of the sesamoid bones."

The suffix "-itis" comes from Greek and always means inflammation. You'll see it in lots of medical words: bronchitis (inflamed airways), arthritis (inflamed joints), and tendonitis (inflamed tendons). When you see "-itis" at the end of a word, you know inflammation is part of the meaning.

A sesamoid bone is a small bone that is embedded in or attached to a tendon (a cord that connects muscle to bone). The word "sesamoid" comes from Greek and means "shaped like a sesame seed" because these bones are tiny and round. In your foot, you have two sesamoid bones under the big toe joint.

Sesamoiditis means the tiny sesamoid bones under your big toe are inflamed and irritated. If someone asks what it is, you can say: "It's inflammation of small bones in the ball of the foot near the big toe."

Many medical conditions use "-itis." Some examples are bursitis (inflamed bursa), gastritis (inflamed stomach lining), and meningitis (inflamed membranes around the brain and spinal cord). All of these words follow the same pattern: the body part, plus "-itis" for inflammation.

There isn't a commonly used abbreviation for sesamoiditis like there is for some other conditions. Doctors usually write or say the full word sesamoiditis, though they might shorten it to "sesamoid" when talking about the bones themselves.

Here's an example: "Her doctor said she had sesamoiditis, which explained the pain in the ball of her foot." Another example: "The physical therapist explained that sesamoiditis affects the small bones under the big toe."
