heterotopic ossification
Pronunciation: het-er-oh-TOP-ik os-if-ih-KAY-shun
Abnormal formation of bone and cartilage in soft tissues where bone does not normally exist.
Full Definition
Heterotopic ossification is a pathological process characterized by the formation of mature bone and cartilage in soft tissues, particularly muscles, tendons, ligaments, and joint capsules, where bone tissue does not normally develop. This complication commonly occurs after orthopedic trauma, surgery, or spinal cord injuries, and can significantly limit joint range of motion and functional mobility. Early recognition and intervention are crucial for preventing permanent functional limitations.
