What does trabecular markings mean?

Trabecular markings refer to the patterns of bony striations or trabeculae observed in bone structures, particularly in the cancellous (spongy) bone. These markings are indicative of the internal architecture of the bone, providing insight into its strength and structural integrity. They can be visualized through imaging techniques such as X-rays or MRI, and their appearance can vary with age, disease, or mechanical loading. In clinical contexts, analyzing trabecular markings can help assess bone health and the risk of fractures.
