subkondraalinen

Subkondraalinen is a medical term derived from Latin, meaning "beneath the cartilage." It refers to the bone located directly below the articular cartilage of a joint. This subchondral bone plays a crucial role in the overall health and function of the joint. It acts as a weight-bearing surface and helps to distribute stress across the joint. The subchondral bone is also characterized by a dense, mineralized outer layer and a more porous inner structure.

Conditions affecting the subchondral bone can significantly impact joint health. For example, subchondral bone cysts are fluid-filled sacs that can form within this layer, often associated with osteoarthritis. These cysts can cause pain and further damage to the joint. Osteonecrosis, also known as avascular necrosis, can affect the subchondral bone if blood supply is compromised, leading to bone death. Stress fractures can also occur in the subchondral bone due to repetitive or excessive forces. Understanding the structure and common pathologies of the subchondral bone is important for diagnosing and managing various joint disorders. Imaging techniques such as X-rays and MRI are commonly used to visualize and assess the condition of the subchondral bone.
