How to Pronounce Legg-Calve-Perthes Disease

Say it like this: LEG kal-VAY PER-teez dih-ZEEZ. The first part rhymes with "leg," the second part sounds like "cal" (rhymes with "pal") plus "VAY" (like the letter V), then "PER" (rhymes with "her") plus "teez" (rhymes with "please"), and finally "dih-ZEEZ" (like "disease"). The stress falls on the second syllable: kal-VAY.

The stressed syllable is VAY in "Calve." Many people mistakenly stress the first syllable and say "LEG-cal-vay," but the correct way puts the emphasis on the middle: leg kal-VAY Perthes. Think of it like "kal-VAY" is the most important part to emphasize.

Break it into five syllables: Legg (1) - Cal (2) - ve (3) - Per (4) - thes (5). It's easier to say if you pause slightly between each part: Legg... Cal-ve... Per-thes. This helps you hear each sound clearly.

"Perthes" comes from Georg Perthes, a German surgeon who helped describe this condition in the early 1900s. In medical naming tradition, doctors often name conditions after the doctors who discovered or studied them, so this disease is named partly in his honor.

In everyday terms, it's a hip condition that occurs in children where the round top part of the thighbone loses its blood supply temporarily. The bone weakens and changes shape, but the body can rebuild it over time. It's often shortened to just "Perthes disease" in casual conversation.

The abbreviation is LCPD, pronounced by saying each letter: "L-C-P-D." Doctors and medical professionals often use this short form in written notes and charts to save time, but the full name is still commonly used when speaking.

While "Perthes" itself comes from a doctor's name, the word "femoral" (relating to the thighbone) often appears alongside it in medical descriptions. You might hear "femoral head" when doctors discuss this condition, since "femoral" comes from the Latin word for thighbone.

Here's an example: "The pediatric orthopedist explained that the child's diagnosis was Legg-Calve-Perthes disease." Or simply: "Her doctor mentioned Perthes disease as a possibility for the hip problem." The term is used when discussing or identifying this specific childhood hip condition.
