heterotopic ossification
Pronunciation: HET-er-oh-TOP-ik os-ih-fih-KAY-shun
Abnormal bone and cartilage formation in soft tissues outside the skeletal system.
Full Definition
Heterotopic ossification refers to the pathological development of bone and cartilage in tissues where bone formation does not normally occur, such as muscles, tendons, and ligaments. This condition is particularly relevant in orthopedic surgery as a potential complication following trauma, burns, or surgical procedures. It can significantly impact joint mobility and function, requiring specific preventive measures and treatment protocols.
Usage
Usage note: Not to be confused with dystrophic calcification, which involves calcium deposits rather than true bone formation.
