Subchondral lucences are clear-appearing areas under the cartilage.
"Lucency" is a technical term for an area that lets x-rays through tissue and appears darker on the picture. "Peri-screw lucency" is a result of having had a peri-screw inserted into the bone, possibly due to an accident.
ageing or degenertive enthesopathy
it is a fluid filled sac under the cartilage
A lucency on an X-ray image represents an area absorbing less radioactive energy than the surrounding tissue. Lucent areas appear dark compared to the surrounding area.
Lucency on medical imaging, such as X-rays, is caused by the passage of X-rays through less dense tissues like air or fluid. This results in those areas appearing darker on the image. Lucency can be seen in conditions like pneumothorax (air in the chest cavity) or pulmonary nodules (small round growth in the lung).
Skull tumor c shaped lucency describes appearance in x-ray.
Helps transmitting loads from the cartilage into the underlying cancellous bone.
yes
There is some thinning of the bone in the pelvis.
Ask again, saying which body part is being imaged.
Related to bone condyles that have swelling beneath the surface. The condyles are the rounded lumpy bits at the end of long thin bones: finger bones (phalanges) or thigh (femur). Subchondral odema occurs commonly when thes bones are forced together sometimes with repeated running on hard surfaces sub femoral or tibial chondral/plataeu or when staving your finger during basket ball straight finger compression. Can take a long time to settle but can settle to no symptoms.
