A chest or thorax bound or constricted, possibly by tight connective tissue or a medical condition affecting the ribcage.
From Greek 'desmos' (bond) and 'thorax' (chest). This is a rare anatomical or medical term combining the root for binding with the term for the chest cavity.
This word is so specialized that even many doctors have never heard it—it's the kind of term that might appear in 19th-century medical textbooks describing rare chest conditions that we'd now diagnose with modern imaging.
