Osteophytes are cartilage-capped bony proliferations (spurs) that develop at the margins of a synovial joint as a response to articular cartilage damage, as seen very commonly in degenerative joint disease. They are considered a hallmark of osteoarthritis and can be confused with syndesmophytes and enthesophytes.
Currently it is unknown if osteophytes are a functional adaptation to joint disease or a pathological phenomenon in their own right 1.
Small osteophytes are sometimes referred to as osteophytic lipping.
