Osteophyte formation has classically been related to sequential and consequential changes in such processes. Often osteophytes form in osteoarthritic joints as a result of damage and wear from inflammation. Calcification and new bone formation can also occur in response to mechanical damage in joints. [5]
An exostosis, also known as a bone spur, is the formation of new bone on the surface of a bone. [1] Exostoses can cause chronic pain ranging from mild to debilitatingly severe, depending on the shape, size, and location of the lesion.
Heberden's nodes are hard or bony swellings that can develop in the distal interphalangeal joints (DIP) (the joints closest to the end of the fingers and toes). [1] They are a sign of osteoarthritis and are caused by formation of osteophytes (calcific spurs) of the articular (joint) cartilage in response to repeated trauma at the joint.
The word cheilectomy comes from the Greek word Cheilos, meaning "lip." A cheilectomy removes the bone spurs, or lip of bone, that forms as a result of arthritis of the joint. Removing the bone spurs, eases pain and lessens stiffness of the big toe. [citation needed]
A bone spur (osteophyte) in the knee is mainly caused by wear and tear of the joint, leading to pain and stiffness. Learn more about the causes and treatment.
New bone outgrowths, called "spurs" or osteophytes, can form on the margins of the joints, possibly in an attempt to improve the congruence of the articular cartilage surfaces in the absence of the menisci. The subchondral bone volume increases and becomes less mineralized (hypo mineralization). [47] All these changes can cause problems ...
The resorption bays are created by the erosive action of osteoclasts on the underlying bone. The border of the lower part of an osteoclast exhibits finger-like processes due to the presence of deep infoldings of the cell membrane; this border is called ruffled border. The ruffled border lies in contact with the bone surface within a resorption bay.
This morphology is typical of a tibial bone spur. Osteochondromas are benign lesions and do not affect life expectancy. [13] Complete excision of osteochondroma is curative and the reoccurrences take place when the removal of tumor is incomplete. Multiple reoccurrences in a well-excised lesion indicate that it may be malignant. [4]
