osteophyte

It can be mistaken for a loose body or osteophyte.

This can be expected to improve and become less prevalent as the individual develops osteophyte formation around the discs.

A bone spur (osteophyte) is a bony growth formed on normal bone.

Early on there is flattening of articular surfaces, thinning of cartilage with osteophyte (spur) formation.

On 5 May 2010, Chan Siu Ki was diagnosed with Osteophyte.

Chronic compression of the nerve root by a persistent agent such as disc, bone (osteophyte) or scarring can also permanently damage the nerve root.

Additional radiographic findings include joint effusion and degenerative changes such as joint space narrowing, subchondral sclerosis, and osteophyte formation.

There may also be shrinkage of the nucleus pulposus that produces prolapse or folding of the annulus with secondary osteophyte formation at the margins of the adjacent vertebral body.

Osteophyte formation has been classically related to any sequential and consequential changes in bone formation that is due to aging, degeneration, mechanical instability, and disease (such as Diffuse Idiopathic Skeletal Hyperostosis).

This process leads to an increased stress transfer to the posterior facet joints, which accelerates cartilaginous degeneration, hypertrophy, and osteophyte formation; this is associated with thickening and buckling of the ligamentum flavum.

The combination of the ventral disk bulging, osteophyte formation at the dorsal facet, and ligamentum flavum hyptertrophy combine to circumferentially narrow the spinal canal and the space available for the neural elements.

"He had a CAT scan, X-rays, an m.r.i. and a bone scan," Hershon said, "and these imaging tests showed an osteophyte - a bone spur - and those don't grow overnight.

Calcaneal spur (heel spur) is a small calcified bone extension (osteophyte) located on the inferior aspect of the calcaneus or on the back of the heel at the insertion of the Achilles tendon.

Associated radiological findings include a vacuum phenomenon (in the nucleus pulposis of the adjacent intervertebral disc), reduction of disc height with corresponding loss of the disc space, marginal sclerosis of the adjacent vertebral bodies, osteophyte formation and apophyseal joint instability.
