If a nonunion fracture never heals and you are stuck with the same broken bones how can you stand up and cook for yourself how can you shower?

It appears that you basically keep asking the same question multiple different ways. A nonunion fracture CAN be treated and CURED by an orthopedic surgeon through surgery. This would return the bone back to its full functional baseline. If you leave the nonunion alone and don't treat, it will not return to its former functional level. You must see an orthopedist to treat this condition.
