osteophyte
Pronunciation: OS-tee-oh-fite
A bony outgrowth or spur that forms at joint margins as a response to cartilage degeneration and joint stress.
Full Definition
An osteophyte is an abnormal bony projection that develops at the periphery of joints as part of the degenerative process associated with osteoarthritis. These bone spurs form as the body attempts to stabilize joints affected by cartilage loss and altered biomechanics. Osteophytes can cause pain, limit joint range of motion, and contribute to joint stiffness. In sports medicine, they are commonly seen in weight-bearing joints of athletes with long careers or those who have sustained previous injuries. While often asymptomatic, large osteophytes may impinge on surrounding soft tissues or contribute to mechanical symptoms.
Usage
Usage note: Specify location and size when clinically significant for surgical planning.
