Clinic
- Also known as a bone spur, is the formation of new bone on the surface of a bone.
- Exostoses can cause chronic pain ranging from mild to debilitatingly severe, depending on the shape, size, and location of the lesion. It is most commonly found in places like the ribs, where small bone growths form, but sometimes larger growths can grow on places like the ankles, knees, shoulders, elbows and hips. Very rarely are they on the skull.
- Exostoses are sometimes shaped like spurs, such as calcaneal spurs.
- Osteomyelitis may leave the adjacent bone with exostosis formation.
- Charcot foot, the neuropathic breakdown of the feet seen primarily in diabetics, can also leave bone spurs.
- They normally form on the bones of joints, and can grow upwards. For example, if an extra bone formed on the ankle, it might grow up to the shin.
- Cartilaginous exostosis = Osteocartilaginous exostosis = Osteochondroma
- Osteophytes are bone spurs that develop on the margins of joints secondary to external stimuli such as osteoarthritis.
