Ludloff stain
The Ludloff spot is named after the physician Karl Ludloff . It describes a circular brightening in the X-ray image with a lateral beam path , which is projected as a so-called epiphyseal triangle ( Ludloff's triangle ) on the two (distal) articular processes of the thigh bone , the femoral condyles , which are far from the center of the body .
It is not a pathological process, so it is harmless and can be seen most clearly around the age of 16 in the growth phase of the body.
This brightening can be used to detect bone tear injuries as the skeleton grows.
Visibility of the Ludloff spot
This brightening is visible on the abdomen ( ventral ) and distal through the bone indentation between the two articular cusps of the distal thighbone (corticalis of the intercondylic fossa). The x-ray shows the epiphyseal line towards the head ( cranial ). Towards the back ( dorsal ) the stain is only vaguely noticeable.
