callus formation
Pronunciation: KAL-us for-MAY-shun
The natural healing process where new bone tissue develops around a fracture site during repair.
Full Definition
Callus formation is the biological process by which the body creates new bone tissue to bridge and heal a fracture. This occurs in stages, beginning with soft callus (cartilage and fibrous tissue) that gradually mineralizes into hard callus (new bone). In orthopedic trauma documentation, proper assessment of callus formation is crucial for determining healing progress and treatment success.
Usage
Usage note: Distinguish from 'callous' (adjective meaning unfeeling); the medical term is always 'callus' (noun).
