Can you get avascular necrosis in your ankle?
Can you get avascular necrosis in your ankle?
Avascular necrosis is an uncommon condition that can affect the bones of the foot or ankle. It is due to a loss of blood supply to the bone or a portion thereof. Loss of blood supply causes death of the bone cells, which may predispose the bone and joint to collapse.
Does avascular necrosis cause inflammation?
When the blood supply is disrupted, the bone tissues begin to break down (necrosis). This can weaken the bone and eventually result in its collapse. If this occurs near a joint, it can lead to the collapse of the joint surface, resulting in pain and inflammation (arthritis).
What is AVN in ankle?
Avascular necrosis of the talus (AVN) refers to a cutoff of the blood supply to the talus, which is a bone of the ankle. It typically results from a fracture in the area that damages the blood vessels. When AVN takes place, the bone may soften and begin to break down.
Where does avascular necrosis hurt?
Pain associated with avascular necrosis of the hip might center on the groin, thigh or buttock. Besides the hip, the areas likely to be affected are the shoulder, knee, hand and foot. Some people develop avascular necrosis on both sides (bilaterally) — such as in both hips or in both knees.
What is the treatment for ankle arthritis with AVN?
Total ankle replacement: Total ankle replacement is now an accepted treatment for ankle arthritis, but cannot always be performed if AVN is present. The ankle replacement must have a good bone to sit on, and if the AVN is extensive, it cannot be performed.
What is talus avicularis (AVN)?
In the case of the talus, 3 joints can be affected; the ankle joint, the talonavicular joint (a joint in the middle of the foot), and the subtalar joint (the joint below the ankle). AVN in the ankle can be caused by one of two main reasons; trauma and non-traumatic.
What is the pathophysiology of ankle pain?
The ankle mortise, which is the articulation of the tibia and talus may both be affected. The talus may be solely affected, or the tibia alone. The navicular bone, adjacent to the talus, may be affected alone, resulting in more foot than ankle pain. Additionally, the metatarsals may be affected, giving rise to forefoot pain.
What bone is affected by ankle fracture?
The ankle mortise, which is the articulation of the tibia and talus may both be affected. The talus may be solely affected, or the tibia alone. The navicular bone, adjacent to the talus, may be affected alone, resulting in more foot than ankle pain.
