Broke my femurs, ankles, ltwrist, fractured hip & dislocated my shoulder in a motorcycle accident. What are some potential issues I should look out 4?

Arthritis. That many bony injuries, you are lucky to be alive. Any fracture associated with joints may become arthritic prematurely over time. Chronic pain is another potential issue. Give up the bike and stay alive.
Everyone heals up. At different rates.Be sure to get proper physical therapy, be consistent and determined to go to all your pt sessions.If your recovery is less than 100%, discus this with the physical therapist, and if necessary, see your treating physician, and develop a plan on how to get you to 100%.Good luck.
