Bone bruises occur due to impact forces or repetitive stress/force on the bone.

What Does Subchondral Mean In Relation To Cartilage?

Subchondral bone is the layer of bone just below the cartilage in a joint. the -chondral refers to cartilage, while the prefix sub means below. Subchondral bone is a shock absorber in weight-bearing joints. It has many blood vessels supplying it with nutrients and oxygen and taking away wastes.

What Kind Of Injury Is A Bone Bruise?

What Causes Cartilage Thinning And Denudation In Subchondral Bone?

Although cartilage thinning and denudation of subchondral bone are changes that characterize both degenerative and inflammatory diseases, the pathogenesis of these changes is different. Deterioration of the articular cartilage in degenerative disease is the result of dehydration and repetitive microtrauma of the cartilage,…

What Does It Mean To Have Subchondral Sclerosis?

In the case of bone, sclerosis means that an area of bone is making more new bone tissue than usual and becoming denser and thicker. So subchondral sclerosis is a thickening and hardening of bone that happens underneath cartilage in a joint. When Subchondral Sclerosis Occurs

What Happens To The Trabeculae Of The Bone?

Trabeculae are aligned with the directions of maximum stress on the bone and can change direction or grow larger in response to forces applied to them, such as those that result from exercise. If the bone isn’t subjected to mechanical stress, as is the case of the astronauts, the trabeculae can shrink and become very fragile.
