Avascular Necrosis Of Tarsal Navicular Bone
Cysts in bone: Cystic changes or erosions in bone post trauma can indicate that the bone matrix was disrupted from the injury and cystic changes have resulted. It does not mean that you have avascular necrosis, but it can mean that there are changes in the trabecular patterns of the bone due to the trauma. Bone injuries can cause many different bone patterns to occur as a result of the bone trying to heal itsel ...Read more
Also known as osteonecrosis, avascular necrosis is the death of bone from interruption of blood supply. This can result in tiny bone fractures and eventual destruction of the entire bone. It can be caused by trauma, blockage of circulation with lipids in the blood, certain diseases like sickle cell disease, Gaucher, and occasionally after exposure to corticosteroids. Sometimes, there ...Read more
Doctor told me my images were consistent with avascular necrosis in the navicular/midfoot. 4 months post injury. What's this mean for me?
After an MRI and X-Ray I was told I likely have avascular necrosis in my navicular following an injury 4 mos ago. Not in much pain though. This norm?
Yes: You need to see an orthopedic surgeon. ...Read more
Subchondral linear focus of hypointense signal at proximal aspect of navicular, which may be subchondral fracture or avascular necrosis. Explain?
Is this an MRI?: It sounds like you are reading an MRI report, what they are describing is abnormal signal on the MRI in your Navicular ( one of the bones in your foot) It sounds like there could be a fracture - maybe you had an injury, or if there was no injury but you have had pain and there is an area just below the surface of the joint that the bone has died (Avascular necrosis- AVN) hope that helps ...Read more
MRI report said either subchondral fracture of navicular or avascular necrosis. If it's a fracture, does that mean it went necrotic? Very confused
Let me explain: Avascular necrosis (and avn) is a disease where there is cellular death (necrosis) of bone components due to interruption of the blood supply.] without blood, the bone tissue dies and the bone collapses. If avascular necrosis involves the bones of a joint, it often leads to destruction of the bone, the bone will there but deformed. ...Read more
Possible: Possible but highly unlikely.Get a more detailed answer ›
Bone is a living growing tissue made mostly of collagen (protein that provides soft framework) & the mineral calcium phosphate that adds strength & hardens the framework. Two types of bone are found in the body; cortical (dense compact outer layer) & trabecular (makes up inner layer, ...Read more
Osteonecrosis is a condition in which part of a person's bone dies due to lack of blood flow to the area. The hip and shoulder are more likely to be affected, but osteonecrosis can also involve the knee, elbow, wrist, or ankle. Trauma to the bone can cause osteonecrosis, often there ...Read more
