Osteonecrosis of the jaw fatty degeneration and/or necrosis, often with pooled fat from destroyed adipose cells (oil cysts) and with marrow fibrosis (reticular fatty degeneration)"" are seen. These changes are present even if ""most bony trabeculae appear at first glance viable, mature and otherwise normal, but closer inspection demonstrates focal loss of osteocytes and variable micro cracking (splitting along natural cleavage planes). The microscopic features are similar to those of ischaemic or aseptic osteonecrosis of long bones, corticosteroid-induced osteonecrosis, and the osteomyelitis of caisson (deep-sea diver's) disease"". In the cancellous portion of femoral head it is not uncommon to find trabeculae with apparently intact
Generative tissue and has a unique cellular and biochemical make-up that make it distinct from other tissues of the body. gTissue was discovered through research in the fields of Tissue Engineering and Regenerative Medicine and first created as a dense connective tissue between the brain and skull during the repair of canine dura mater. It has since been successfully created in humans for a wide range of clinical applications in soft tissue healing and repair. Essentially, the gTissue is created by implanting certain types of non-inflammatory ECM biomaterials that are adopted by the host, including repopulation with host cells and blood vessels,
