As we know that Bo Jackson was a baseball and football player and sustained an injury in 1991, which ended his career. I watched the video of the injury and although there’s a feeling that Bo Jackson dislocated his hip, it’s more likely that he injured his hip or fractured his hip.
This injury probably cut off the blood supply to the head of the femur leading to avascular fitness. It’s unlikely for a native hip to be relocated without anesthesia. A native hip is a very stable joint and if dislocated it needs anesthesia, and a surgical maneuver to relocate the hip. I therefore feel that in the case of Bo Jackson, it was a break in his bone that cut off the blood supply that led to avascular necrosis and a subsequent end to his career.
