The word "sternopagus" refers to a medical condition where an embryo or fetus has developed inside of the chest cavity. The spelling of this word can be explained through International Phonetic Alphabet (IPA) transcription, which is /ˌstɜː.nəˈpeɪ.ɡəs/. The first syllable "ster" is pronounced with the vowel sound /ɜː/, while the second syllable "no" is pronounced with the vowel sound /ə/. The final syllable "pagus" is pronounced with the stress on the second syllable, and the vowel sounds /eɪ/ and /əs/.
Sternopagus is a medical term used to describe a specific condition known as conjoined twins or "thoracopagus twins" who are fused at the level of the sternum or breastbone. Conjoined twins are extremely rare occurrences where two babies are physically connected to one another, sharing vital organs and/or body structures. The term sternopagus specifically refers to the region around the sternum or the breastbone, which is the bone located in the center of the chest.
In the case of sternopagus twins, the fusion occurs in the chest area, typically involving the breastbone and possibly the heart and lungs. The exact nature of the fusion differs from case to case, and the extent of the connection between the twins can vary. This unique developmental anomaly can present significant challenges for medical professionals, as separating the twins often requires intricate surgical procedures and carries a high risk of complications.
The term sternopagus is specifically used within the medical field to indicate the anatomical connection between conjoined twins in the area of the sternum. It is important to note that sternopagus refers only to the physical fusion itself and does not encompass the broader medical or emotional implications associated with the condition.
