Avascular Necrosis

When blood supply is cut off to the bone, leading to the death of bone tissue, this is known as avascular necrosis. This loss of bone tissue can have severe consequences for those impacted by it.


What causes avascular necrosis?

Injuries or accidents that impact a joint and nearby blood vessels are a frequent cause of avascular necrosis. It can also occur due to blood vessel blockages from fats or as a complication of certain diseases.


What are the symptoms of avascular necrosis?

Joint pain that gradually worsens over time is the most common symptoms of avascular necrosis. Eventually the pain can become severe and persistent.


What are avascular necrosis care options?

Early on, pain relievers and other medications can be used to treat avascular necrosis. As the disease progresses, it may require surgical procedures and other therapies to remove the damaged portion of bone and replace it with new bone.

April Patient of the Month: Lucky
04/09/2018 — Lucky started going to physical therapy when he was two because of the delays with sitting up and rolling over. His physical therapist noticed that the problem was not muscular but skeletal, a condition that she couldn't treat. The pediatrician told Janie and Greg, Lucky’s parents, about Nicklaus Children's Hospital. When Janie and Greg visited Nicklaus Children’s Hospital, they met Dr. Harry L Shufflebarger, Pediatric Spinal Surgery Director. He performed the necessary surgeries and now Lucky can enjoy a healthy life.
