Avascular necrosis (AVN) is a condition where the blood supply to the bones is disrupted, leading to bone death and eventually, in some cases, joint destruction. The likelihood of developing AVN depends on a number of factors, including age, underlying medical conditions, and lifestyle.
Older age is a risk factor for developing AVN. As the body ages, the blood vessels that supply the bones with oxygen and nutrients can become stiffer and narrower, making it harder for the bone to receive the necessary nourishment. Additionally, medical conditions such as diabetes, cancer, and lupus can increase the risk of AVN, as can lifestyle choices such as smoking, excessive alcohol use, and steroid use.
The exact likelihood of developing AVN is difficult to predict, as it depends on the individual’s particular circumstances. However, it is estimated that between 10-25% of people with underlying medical conditions such as diabetes, cancer, or lupus will develop AVN. Additionally, those with a history of steroid use, smoking, or excessive alcohol use are at higher risk of developing the condition.
Overall, the likelihood of avascular necrosis depends on several factors, including age, underlying medical conditions, and lifestyle choices. While the exact likelihood is difficult to predict, it is estimated that between 10-25% of those with underlying medical conditions may develop the condition, and those with a history of steroid use, smoking, or excessive alcohol use are at higher risk.
