My nose was broken in a fight. It is now flat on the upper ridge. Can my nose be fixed?

 A rhinoplasty can accomplish fixing a broken nose. Osteotomies are performed to straighten the broken and crooked nasal bones. Cartilage grafting techniques, such as a spreader graft are also used when the upper lateral cartilages have been fractured off the nasal bones. Also important to evaluate the internal portion of the nose since many times the septum becomes fractured, also known as a deviated nasal septum. Repairing a broken nose is very difficult procedure, so choose your surgeon very widely based on experience

Fixing a nose that was just broken versus one that was injured weeks, months, or years ago are very different things.  If you had your nose injured recently (days), get in immediately to a plastic surgeon or ENT facial plastic surgeon, as the correction now will usually be quick, cheap, and predictable.  If this is not a fresh injury, a secondary rhinoplasty will be needed: not quick, not cheap, and less predictable.
