What was so bad about Jackson’s injury? His
hip dislocation wasn’t the problem. Instead, it was what happened in the aftermath of the injury.
During his recovery, Jackson developed a bone disease called
avascular necrosis (AVN). It’s what can happen when the blood supply to the bone is disrupted. When the ball is pulled from the socket, blood vessels are torn or stretched in a way that reduces blood flow.
As bone dies off, it leaves the hip ball with what are essentially potholes. Soon, the cartilage in the joint collapses, creating a bone-on-bone situation that creates significant pain when the hip moves. The only solution at that point is a hip replacement.
