What options are available to someone who broke their hand and did not seek treatment until 5 weeks later, was told it was basically to late to treat?

Well...: That is a tough one. Essentially the healing process of bone growth and re-structuring around the fracture site would have taken place already. I would recommend you see a hand surgeon, have them do a full assessment of your hand and review all and any x-rays, and then depending on how the hand healed, your options for any treatments will be forthcoming. Best wishes.
