Additionally, the outer shell of the long bone is compact bone, then a deeper layer of cancellous bone ( spongy bone ) which contains in the medullary cavity the bone marrow.

Today a growing body of scientific evidence indicate that this disease process, in the cancellous bone and bone marrow, is caused by bone infarcts mediated by a range of local and systemic factors.

The hypothesis was that harvesting a mixture of articular cartilage and cancellous bone would combine pluripotent cells of the cancellous bone with cartilage extracellular matrix and growth factors and when exposed to continuous motion, hyaline-like cartilage would be stimulated to form.

Water has an attenuation of 0 Hounsfield units ( HU ), while air is " 1000 HU, cancellous bone is typically + 400 HU, cranial bone can reach 2000 HU or more ( os temporale ) and can cause artifacts.
36.
Paste grafting involves replacing damaged cartilage with autologous cartilage and cancellous bone from the intercondylar notch in the center of the knee that is first morselized into a paste ( typically with hydroxyapatite ) to better fill the defect and more successfully promote chondrocyte activity and cartilage formation.
37.
While there he continued his active participation at the Sun Valley Workshops where he interacted with participants to develop cancellous bone histomorphomety ( 1977 ), generate and refine the mechanostat hypothesis ( 1987 ), and the ever-evolving Utah Paradigm of Bone Physiology ( 1997 ), and many, many more.
